    Item 1. Business

    (a) General Development of Business

        Thermo Sentron Inc. (the Company or the Registrant) designs,
    develops, manufactures, and sells high-speed precision-weighing and
    inspection equipment for industrial production and packaging lines. The
    Company serves two principal markets: packaged goods and bulk materials.
    The Company's products for the packaged-goods market include a broad
    line of checkweighing equipment and metal detectors that can be
    integrated at various stages in production lines for process control and
    quality assurance. The Company's bulk-materials product line includes
    conveyor-belt scales, solid level-measurement and conveyor-monitoring
    systems, and sampling systems. 

        The Company was incorporated in Delaware in November 1995 as a wholly
    owned subsidiary of Thermedics Inc. (Thermedics), a publicly traded
    subsidiary of Thermo Electron Corporation (Thermo Electron). The Company
    was operated as Ramsey Technology Inc., a wholly owned subsidiary of
    Baker Hughes Incorporated (Baker Hughes), prior to its March 16, 1994,
    acquisition by Thermedics. In January 1996, the Company acquired Hitech
    Electrocontrols Limited (Hitech), a U.K.-based manufacturer of metal-
    detection equipment and specialty checkweighing equipment for the baking
    industry, and in April 1996, the assets of the solids flow-measurement
    product line of Endress + Hauser, Inc. (Endress + Hauser).

        In April 1996, the Company sold 2,875,000 shares of its common stock
    in an initial public offering at $16.00 per share for net proceeds of
    $42.3 million. As of December 28, 1996, Thermedics owned 7,000,000 shares
    of the Company's common stock, representing 71% of such stock
    outstanding. In addition to the Company's products, Thermedics develops,
    manufactures, and markets product quality- assurance systems,
    electrochemistry and microweighing products, electronic-test instruments,
    explosives-detection devices, and moisture-analysis systems, as well as
    implantable heart-assist systems and other biomedical products. As of
    December 28, 1996, Thermo Electron owned 250,000 shares of the Company's
    common stock, representing 3% of such stock outstanding. These shares
    were purchased during 1996* in the open market for a total price of
    $4,006,000. Thermo Electron is a world leader in environmental monitoring
    and analysis instruments, papermaking and recycling equipment, biomedical
    products such as heart-assist devices and mammography systems, biomass
    electric power generation, and other specialized products and
    technologies. Thermo Electron also provides a range of services related
    to environmental quality.

    * References to 1996, 1995, and 1994 herein are for the fiscal years
      ended December 28, 1996, December 30, 1995, and December 31, 1994,
      respectively. The fiscal year ended December 31, 1994, includes the
      Company's financial results for the period from March 16, 1994, the
      date Ramsey Technology Inc. was acquired by Thermedics, through
      December 31, 1994.

    (b)  Information About Industry Segments

        The Company is engaged in one business segment: the design,
    manufacture, and marketing of precision-weighing and inspection
    equipment.

    (c) Description of Business

    Products for Packaged Goods

        Sales of products for the packaged-goods market represented
    approximately 37% of the Company's total revenues in 1996 and account
    for an increasing portion of the Company's business. These products are
    sold primarily to customers in the food-processing and pharmaceutical
    industries.

        Checkweighing Equipment. The Company's checkweighing products weigh,
    classify, and reject packages moving at high speeds (more than 600
    packages per minute) with accuracy to the three-gram level. The Company
    also offers checkweighing products that are accurate to the 50-milligram
    level for pharmaceutical and other high-accuracy applications. By
    assuring that packages contain designated quantities of materials, the
    Company's checkweighing equipment is used to satisfy customer demand and
    regulatory requirements for quality standards and to improve
    productivity by minimizing product giveaway.

        The Company has developed a proprietary database of methodologies
    and designs that it uses to create custom weighing solutions for
    particular applications, such as retrofitting packaging lines in
    response to changes in package size, type, and design. The Company
    believes that its proprietary database provides it with a competitive
    advantage by allowing it to deliver customized weighing equipment on a
    timely and cost-effective basis.

        The Company produces a complete line of electronic in-line
    checkweighing products ranging from devices designed solely to reject
    underweight products, to sophisticated machines with comprehensive
    statistical data-collection and production-monitoring capabilities,
    allowing customers to monitor the deviation from target weight, the

                                        3PAGE
<PAGE>
    number of rejections, and the amount of product giveaway. The Company
    also produces the only checkweighing products specifically designed to
    satisfy the Good Manufacturing Practices (GMP) requirements of the
    pharmaceutical industry.

        Metal Detectors. Metal detectors are used to inspect packaged
    products for metal contaminants. The Company offers metal detectors
    capable of detecting a small metal particle (approximately one
    millimeter in diameter) in a package moving on a conveyor belt at speeds
    in excess of 300 feet per minute.

        In connection with its acquisition of Hitech, the Company acquired
    patented self-testing technology for use with metal-detection products.
    This technology allows an operator to program a metal detector to
    automatically route a metal object through the device at preset
    intervals without operator assistance or interruption to the production
    process. The results of these tests can be tracked by computer and
    incorporated into quality- and process-control reports. The Company
    introduced this new patented feature as part of its metal-detection
    product line in 1996.

        Other Products for Packaged Goods. Other complementary packaged-
    goods products offered by the Company include canned-goods label
    inspectors and various conveying and product-handling devices to assist
    in the presentation of products to the Company's checkweighing equipment
    and metal detectors and the rejecting and handling of unacceptable
    products from the customer's production line.

        Revenues from products for packaged goods were $25,861,000,
    $23,700,000, and $17,321,000 in 1996, 1995, and the period from March
    16, 1994, through December 31, 1994, respectively.

    Products for Bulk Materials

        Sales of products for the bulk-materials market represented
    approximately 63% of the Company's total revenues in 1996. These
    products are sold primarily to customers in the mining and
    material-processing industries, as well as to electric utilities,
    chemical, and other manufacturing companies.

        Conveyor-Belt Scales. The Company offers a wide variety of
    conveyor-belt scales for use in industrial and other applications. A
    conveyor-belt scale is a device that measures the speed at which bulk
    material is being conveyed and delivered on a moving conveyor belt, as
    well as the total mass of material conveyed over a given time.

        The Company's conveyor-belt scales are typically used to measure
    production rates and monitor inventory, to control the speed of flow of
    measured materials or other related materials for blending purposes, and
    to monitor process performance. Conveyor-belt scales are used in many
    industries, including mining, construction materials, power, food-
    processing, pulp and paper, chemicals, and solids recycling. By
    eliminating a separate weighing procedure from the production process,
    conveyor-belt scales are used to streamline operations in these
    industries.
                                        4PAGE
<PAGE>
        The Company's conveyor-belt scales are well-suited for the weighing
    of materials traveling at high speeds and for processes requiring high
    accuracy. These products make use of the Company's proprietary
    algorithms and applications expertise to measure material moving at
    speeds in excess of 10,000 tons per hour with accuracy to within the
    0.125% level. The Company's conveyor-belt scales may also be linked to a
    computer for system process-control. This communications capability is
    designed to assist customers in monitoring inventory, preparing quality-
    control reports, and operating production lines more efficiently.

        The Company incorporates its conveyor-belt scales into short-length
    conveyors called weigh belt-feeders. These products are used both to
    weigh materials in motion and to adjust the speed of the conveyor belt
    to control the amount of material fed in connection with a production
    process.

        The Company's conveyor-belt scales include models for process
    monitoring (with accuracy to within 1%), models for plant-control and
    inventory and stock piling services (with accuracy to within 0.5%), and
    high-precision models for use in the transfer of custody of goods
    requiring government agency certification and approvals (with accuracy
    to within 0.125%).

        Sampling Systems. The Company provides a number of different systems
    that extract and collect statistically representative samples of bulk
    materials for quality-control purposes. Sampling systems are typically
    used to mechanically extract a small amount of material (the sample)
    from a moving conveyor so that the material can be taken to an
    analytical laboratory for testing. The Company's sampling systems are
    used at mine sites, shipping facilities, transfer stations, steel mills,
    cement plants, and coal-fired power plants. The Company's sampling
    systems are used by manufacturers and their customers to ensure that
    products conform to desired specifications at the time of both shipment
    and delivery.

        The Company offers a variety of sampling solutions, including
    "sweep" samplers, which extract samples from any location on a moving
    conveyor belt, and self-contained sampling units, which provide a
    modular approach to sampling without expensive integration into the
    user's material-handling system.

        Other Bulk-Material Products. The Company's solid level-measurement
    and conveyor-monitoring products include safety pull, belt run-off, and
    tilt switches; speed-monitoring devices; contents-monitoring systems;
    and grade, slope, and material feed controls for asphalt paving
    machines. The Company's other complementary bulk-material products
    include tramp metal detectors, front-end loader scales, and static
    weighing and batching equipment. These products are often incorporated
    into complete weighing solutions the Company provides to its customers.

        Revenues from products for bulk materials were $44,166,000,
    $43,774,000, and $32,795,000 in 1996, 1995, and the period from March
    16, 1994, through December 31, 1994, respectively.
                                        5PAGE
<PAGE>
    Distribution of Products

        The Company markets and distributes its products primarily through
    manufacturer's representatives. It also relies upon a direct sales
    force, distributors, and original equipment manufacturers.

    Raw Materials

        The C-level sensor used as a component of one of the Company's
    bulk-materials products is supplied by a sole-source vendor. Although
    the Company has not experienced any difficulty in obtaining adequate
    supplies from this vendor, there can be no assurance that the licensor
    will be able to furnish the Company with a suffiencient number of
    C-level sensors to meet customer demand. The Company believes that the
    unanticipated loss of this vendor would not result in a material adverse
    effect on the Company's business.

    Patents, Licenses, and Trademarks

        The Company's proprietary methodologies, designs, and other
    proprietary intellectual rights are important to the Company's
    operations. The Company relies upon a combination of patent, trade
    secret, nondisclosure, and other contractual arrangements, as well as
    copyright and trademark laws, to protect its proprietary rights. The
    Company seeks to limit access to and distribution of its proprietary
    information. There can be no assurance that the steps taken by the
    Company in this regard will be adequate to deter misappropriation of its
    proprietary information, that the Company will be able to detect
    unauthorized use and take appropriate steps to enforce its intellectual
    property rights, or that competitors will not be able to develop similar
    technology independently.

        The Company currently holds issued U.S. patents expiring at various
    dates ranging from December 1997 to September 2010. The Company also has
    applications pending for additional U.S. patents and a number of foreign
    counterparts for its patents in various foreign countries. In addition,
    the Company has certain registered and other trademarks and is a licensee
    of a patent for its C-level sensors. The Company believes that its
    products, trademarks, and other proprietary rights do not infringe the
    proprietary rights of third parties. There can be no assurance, however,
    that third parties will not assert infringement claims in the future.

    Backlog

        The Company's backlog of unfilled orders was $14.2 million and $11.2
    million as of December 28, 1996, and December 30, 1995, respectively. The
    Company anticipates that substantially all of the backlog at December 28,
    1996, will be shipped during 1997. The Company does not believe that the
    size of its backlog is necessarily indicative of intermediate or
    long-term trends in its business.

                                        6PAGE
<PAGE>
    Competition

        The Company encounters and expects to continue to encounter intense
    competition in the sale of its products. The Company's principal
    competitors in the packaged-goods market are Ishida Scales Mfg. Co., Ltd.
    and Mettler-Toledo AG. In the more fragmented bulk-materials market, the
    Company competes on a worldwide basis primarily with Carl Schenck AG and
    Milltronics Corporation. The Company believes that the principal
    competitive pressures affecting the market for precision-weighing and
    inspection equipment include customer service and support, quality and
    reliability, price, accuracy, ease of use, distribution channels,
    technical features, compatibility with customers' manufacturing
    processes, and regulatory approvals. Certain of the Company's competitors
    have greater resources, manufacturing and marketing capabilities,
    technical staff, and production facilities than those of the Company. As
    a result, they may be able to adapt more quickly to new or emerging
    technologies and changes in customer requirements, or to devote greater
    resources to the promotion and sale of their products, than can the
    Company. Competition could increase if new companies enter the market or
    if existing competitors expand their product lines.

    Research and Development

        Research and development expenses for the Company were $1,881,000,
    $1,920,000, and $1,228,000 in 1996, 1995, and the period from March 16,
    1994, through December 31, 1994, respectively.

    Environmental Protection Regulations

        The Company believes that compliance by the Company with federal,
    state, and local environmental protection regulations will not have a
    material adverse effect on its capital expenditures, earnings, or
    competitive position.

    Number of Employees

        As of December 28, 1996, the Company employed approximately 425
    people.

    (d) Financial Information About Exports by Domestic Operations and About
        Foreign Operations

        Financial information about exports by domestic operations and about
    foreign operations is summarized in Note 10 to Consolidated Financial
    Statements in the Registrant's 1996 Annual Report to Shareholders and is

    To the Shareholders and Board of Directors of Thermo Sentron Inc.:

        We have audited, in accordance with generally accepted auditing
    standards, the consolidated financial statements included in Thermo
    Sentron Inc.'s Annual Report to Shareholders incorporated by reference in
    this Form 10-K, and have issued our report thereon dated February 6,
    1997. Our audits were made for the purpose of forming an opinion on those
    statements taken as a whole. The schedule listed in Item 14 on page 11 is
    the responsibility of the Company's management and is presented for
    purposes of complying with the Securities and Exchange Commission's rules
    and is not part of the basic consolidated financial statements. This
    schedule has been subjected to the auditing procedures applied in the
    audits of the basic consolidated financial statements and, in our
    opinion, fairly states in all material respects the consolidated
    financial data required to be set forth therein in relation to the basic
    consolidated financial statements taken as a whole.

        first business day of each fiscal quarter and shall be in effect
        for the entirety such fiscal quarter;
         
             (g)  "Purchase Price", the price at which Purchased

        3.   Transactions

             (a)  A Transaction may be initiated by Buyer upon the

<PAGE>
        aggregate Repurchase Price for such Purchased Securities, then
        Seller shall transfer to Buyer additional Securities ("Additional
        Purchased Securities"), so that the aggregate Market Value of
        such Purchased Securities, including any such Additional
        Purchased Securities, will thereupon equal or exceed 103% of such
        aggregate Repurchase Price.

             (b)  If at any time the aggregate Market Value of all
        Purchased Securities then owned by Buyer exceeds 103% of the
        aggregate Repurchase Price for such Purchased Securities, then
        Seller may transfer Purchased Securities to Seller, so that the
        aggregate Market Value of such Purchased Securities will
        thereupon not exceed 103% of such aggregate Repurchase Price.

        5.   Interest Payments

             If during any fiscal month Buyer owned Purchased Securities,
        then on the first day of the next following fiscal month Seller
        shall pay to Buyer an amount equal to the sum of the aggregate
        Repurchase Prices of the Purchased Securities owned by Buyer at
        the close of each day during the preceding fiscal month divided
        by the number of days in such month and the product multiplied by
        the Pricing Rate times the number of days in such month divided
        by 360.

        6.   Income Payments and Voting Rights

             Where a particular Transaction's term extends over an Income
        payment date on the Purchased Securities subject to that
        Transaction, Buyer shall, on the date such Income is payable,
        transfer to Seller an amount equal to such Income payment or
        payments with respect to any Purchased Securities subject to such
        Transaction.  Seller shall retain all voting rights with respect
        to Purchased Securities sold to Buyer under this Agreement.


        7.   Security Interest

             Although the parties intend that all Transactions hereunder
        be sales and purchases and not loans, in the event any such
        Transactions are deemed to be loans, Seller shall be deemed to
        have pledged to Buyer as security for the performance by Seller
        of its obligations under each such Transaction and this
        Agreement, and shall be deemed to have granted to Buyer a
        security interest in, all of the Purchased Securities with
        respect to all Transactions hereunder and all proceeds thereof.

        8.   Payment and Transfer

             Unless otherwise mutually agreed, all transfers of funds
        hereunder shall be in immediately available funds.  As used
        herein with respect to Securities, "transfer" is intended to have

                                        3PAGE
<PAGE>
        the same meaning as when used in Section 8-313 of the
        Massachusetts Uniform Commercial Code or, where applicable, in
        any federal regulation governing transfers of the Securities.

        9.   Substitution

             Buyer hereby grants Seller the authority to manage, in
        Seller's sole discretion, the Purchased Securities held in
        custody for Buyer by Seller in the Repurchase Collateral Account.
        Buyer expressly agrees that Seller may (i) substitute other
        Securities for any Purchased Securities and (ii) commingle
        Purchased Securities with other Securities held in the Repurchase
        Collateral Account.  Substitutions shall be made by transfer to
        Buyer of such other Securities and transfer to Seller of the
        Purchased Securities for which substitution is being made.  After
        substitution, the substituted Securities shall be deemed to be
        Purchased Securities.  Securities which are substituted for
        Purchased Securities shall have a Market Value at the time of
        substitution equal to or greater than the Market Value of the
        Purchase Securities for which such Securities were substituted.

        10.  Representations

             Each of Buyer and Seller represents and warrants to the
        other that (i) it is duly authorized to execute and deliver this
        Agreement, to enter into the Transactions contemplated hereunder
        and to perform its obligations hereunder and has taken all
        necessary action to authorize such execution, delivery and
        performance, (ii) the person signing this Agreement on its behalf
        is duly authorized to do so on its behalf, (iii) it has obtained
        all authorizations of any governmental body required in
        connection with this Agreement and the Transactions hereunder and
        such authorizations are in full force and effect and (iv) the
        execution, delivery and performance of this Agreement and the
        Transactions hereunder will not violate any law, ordinance,
        charter, by-law or rule applicable to it or any agreement by
        which it is bound or by which any of its assets are affected.  On
        the date for any Transaction Buyer and Seller shall each be
        deemed to repeat all the foregoing representations made by it.

        11.  Events of Default

             In the event that (i) Seller fails to repurchase or Buyer
        fails to transfer Purchased Securities upon demand for repurchase
        from either Buyer or Seller, (ii) Seller or Buyer fails, after
        one business day's notice, to comply with Paragraph 4 hereof,
        (iii) Buyer fails to make payment to Seller pursuant to Paragraph
        6 hereof, (iv) Seller fails to comply with Paragraph 5 hereof,
        (v) an Act of Insolvency occurs with respect to Seller or Buyer,
        (vi) any representation made by Seller or Buyer shall have been
        incorrect or untrue in any material respect when made or repeated
        or deemed to have been made or repeated, or (vii) Seller or Buyer
        shall admit to the other its inability to, or its intention not

                                        4PAGE
<PAGE>
        to, perform any of its obligations hereunder (each an "Event of
        Default"):

             (a)  At the option of the nondefaulting party, exercised by
        written notice to the defaulting party (which option shall be
        deemed to have been exercised, even if no notice is given,
        immediately upon the occurrence of any Act of Insolvency), Seller
        shall become obligated to repurchase, and Buyer shall become
        obligated to sell, all Purchased Securities then owned by Buyer
        for the Repurchase Price of such Purchased Securities.

             (b)  If Seller is the defaulting party and Buyer exercises
        or is deemed to have exercised the option referred to in
        subparagraph (a) of this Paragraph, (i) the Seller's obligations
        hereunder to repurchase all Purchased Securities in such
        Transactions shall thereupon become immediately due and payable,
        (ii) all Income paid after such exercise or deemed exercise shall
        be retained by Buyer and applied to the aggregate unpaid
        Repurchase Prices owed by Seller, and (iii) Seller shall
        immediately deliver to Buyer any Purchased Securities subject to
        such Transactions then in Seller's possession.

             (c)  In all Transactions in which Buyer is the defaulting
        party, upon tender by Seller of payment of the aggregate
        Repurchase Prices for all such Transactions, Buyer's right, title
        and interest in all Purchased Securities subject to such
        Transactions shall be deemed transferred to Seller, and Buyer
        shall deliver all such Purchased Securities to Seller.

             (d)  After one business day's notice to the defaulting party
        (which notice need not be given if an Act of Insolvency shall
        have occurred, and which may be the notice given under
        subparagraph (a) of this Paragraph or the notice referred to in
        clause (ii) of the first sentence of this Paragraph), the
        nondefaulting party may: 

                  (i)  as to Transactions in which Seller is the
        defaulting party, (A) immediately sell, in a recognized market at
        such price or prices as Buyer may reasonably deem satisfactory,
        any or all Purchased Securities subject to such Transactions and
        apply the proceeds thereof to the aggregate unpaid Repurchase
        Prices and any other amounts owing by Seller hereunder or (B) in
        its sole discretion elect, in lieu of selling all or a portion of
        such Purchased Securities, to give Seller credit for such
        Purchased Securities in an amount equal to the price therefor on
        such date, obtained from a generally recognized source or the
        most recent closing bid quotation from such a source, against the
        aggregate unpaid Repurchase Prices and any other amounts owing by
        Seller hereunder; and

                  (ii)  as to Transactions in which Buyer is the
        defaulting party, (A) purchase securities ("Replacement
        Securities") of the same class and amount as any Purchased
        Securities that are not delivered by Buyer to Seller as required

                                        5PAGE
<PAGE>
        hereunder or (B) in its sole discretion elect, in lieu of
        purchasing Replacement Securities, to be deemed to have purchased
        Replacement Securities at the price therefor on such date,
        obtained from a generally recognized source or the most recent
        closing bid quotation from such a source.

             (e)  As to Transactions in which Buyer is the defaulting
        party, Buyer shall be liable to Seller (i) with respect to
        Purchased Securities (other than Additional Purchased
        Securities), for any excess of the price paid (or deemed paid) by
        Seller for Replacement Securities therefor over the Repurchase
        Price for such Purchased Securities and (ii) with respect to
        Additional Purchased Securities, for the price paid (or deemed
        paid) by Seller for the Replacement Securities therefor.  

             (g)  The defaulting party shall be liable to the
        nondefaulting party for the amount of all reasonable legal or
        other expenses incurred by the nondefaulting party in connection
        with or as a consequence of an Event of Default.

             (h)  The nondefaulting party shall have, in addition to its
        rights hereunder, any rights otherwise available to it under any
        other agreement or applicable law.

        12.  Single Agreement

             Buyer and Seller acknowledge that, and have entered hereinto
        and will enter into each Transaction hereunder in consideration
        of and in reliance upon the fact that, all Transactions hereunder
        constitute a single business and contractual relationship and
        have been made in consideration of each other.  Accordingly, each
        of Buyer and Seller agrees (i) to perform all of its obligations
        in respect of each Transaction hereunder, and that a default in
        the performance of any such obligations shall constitute a
        default by it in respect of all Transactions hereunder, (ii) that
        each of them shall be entitled to set off claims and apply
        property held by them in respect of any Transaction against
        obligations owing to them in respect of any other Transactions
        hereunder and (iii) that payments, deliveries and other transfers
        made by either of them in respect of any Transaction shall be
        deemed to have been made in consideration of payments, deliveries
        and other transfers in respect of any other Transactions
        hereunder, and the obligations to make any such payments,
        deliveries and other transfers may be applied against each other
        and netted.

        13.  Entire Agreement; Severability

             This Agreement shall supersede any existing agreements
        between the parties containing general terms and conditions for
        repurchase transactions.  Each provision and agreement and
        agreement herein shall be treated as separate and independent
        from any other provision or agreement herein and shall be

                                        6PAGE
<PAGE>
        enforceable notwithstanding the unenforceability of any such
        other provision or agreement.

        14.  Non-assignability; Termination

             The rights and obligations of the parties under this
        Agreement and under any Transactions shall not be assigned by
        either party without the prior written consent of the other
        party.  Subject to the foregoing, this Agreement and any
        Transactions shall be binding upon and shall inure to the benefit
        of the parties and their respective successors and assigns.  This
        Agreement may be canceled by either party upon giving written
        notice to the other, except that this Agreement shall,
        notwithstanding such notice, remain applicable to any
        Transactions then outstanding.

        15.  Governing Law

             This Agreement shall be governed by the laws of the
        Commonwealth of Massachusetts without giving effect to the
        conflict of law principles thereof.

        16.  No Waivers, Etc.

             No express or implied waiver of any Event of Default by
        either party shall constitute a waiver of any other Event of
        Default and no exercise of any remedy hereunder by any party
        shall constitute a wavier of its right to exercise any other
        remedy hereunder.  No modification or waiver of any provision of
        this Agreement and no consent by any party to a departure
        herefrom shall be effective unless and until such shall be in
        writing and duly executed by both of the parties hereto. 

        17.  Intent

             (a)  The parties recognize that each Transaction is a
        "repurchase agreement" as that term is defined in Section 101 of
        Title 11 of the United States Code, as amended (except insofar as
        the type of Securities subject to such Transaction or the term of
        such Transaction would render such definition inapplicable), and
        a "securities contract" as that term is defined in Section 741 of
        Title 11 of the United States Code, as amended.

             (b)  It is understood that either party's right to liquidate
        Securities delivered to it in connection with Transactions
        hereunder or to exercise any other remedies pursuant to Paragraph
        11 hereof, is a contractual right to liquidate such Transaction
        as described in Sections 555 and 559 of Title 11 of the United
        States Code, as amended.

        By:  Jonathan W. Painter           By:  Lewis J. Ribich
        Name:     Jonathan W. Painter      Name:     Lewis J. Ribich
        Title:    Treasurer                Title:    President  


                                                        EXHIBIT 10.11

                               THERMO SENTRON INC.

                      RESTATED STOCK HOLDING ASSISTANCE PLAN

        SECTION 1.   Purpose.

             The purpose of this Plan is to benefit Thermo Sentron Inc.
        (the "Company") and its stockholders by encouraging Key Employees
        to acquire and maintain share ownership in the Company, by
        increasing such employees' proprietary interest in promoting the
        growth and performance of the Company and its subsidiaries and by
        providing for the implementation of the Stock Holding Policy.  

        SECTION 2.     Definitions.

             The following terms, when used in the Plan, shall have the
        meanings set forth below:

             Committee:   The Human Resources Committee of the Board of
        Directors of the Company as appointed from time to time.

             Common Stock:   The common stock of the Company and any
        successor thereto.

             Company:   Thermo Sentron Inc., a Delaware corporation.

             Stock Holding Policy:   The Stock Holding Policy of the
        Company, as adopted by the Committee and as in effect from time
        to time.

             Key Employee:   Any employee of the Company or any of its
        subsidiaries, including any officer or member of the Board of
        Directors who is also an employee, as designated by the
        Committee, and who, in the judgment of the Committee, will be in
        a position to contribute significantly to the attainment of the
        Company's strategic goals and long-term growth and prosperity.

             Loans:   Loans extended to Key Employees by the Company
        pursuant to this Plan.

             Plan:   The Thermo Sentron Inc. Stock Holding Assistance
        Plan, as amended from time to time.

        SECTION 3.     Administration.

             The Plan and the Stock Holding Policy shall be administered
        by the Committee, which shall have authority to interpret the
        Plan and the Stock Holding Policy and, subject to their
        provisions, to prescribe, amend and rescind any rules and
        regulations and to make all other determinations necessary or
        desirable for the administration thereof.  The Committee's
        interpretations and decisions with regard to the Plan and the
        Stock Holding Policy and such rules and regulations as may be
PAGE
<PAGE>
        established thereunder shall be final and conclusive.  The
        Committee may correct any defect or supply any omission or
        reconcile any inconsistency in the Plan or the Stock Holding
        Policy, or in any Loan in the manner and to the extent the
        Committee deems desirable to carry it into effect.  No member of
        the Committee shall be liable for any action or omission in
        connection with the Plan or the Stock Holding Policy that is made
        in good faith.

        SECTION 4.     Loans and Loan Limits.

             The Committee has determined that the provision of Loans
        from time to time to Key Employees in such amounts as to cause
        such Key Employees to comply with the Stock Holding Policy is, in
        the judgment of the Committee, reasonably expected to benefit the
        Company and authorizes the Company to extend Loans from time to
        time to Key Employees in such amounts as may be requested by such
        Key Employees in order to comply with the Stock Holding Policy.
        Such Loans may be used solely for the purpose of acquiring Common
        Stock (other than upon the exercise of stock options or under
        employee stock purchase plans) in open market transactions or
        from the Company.

             Each Loan shall be full recourse and evidenced by a
        non-interest bearing promissory note substantially in the form
        attached hereto as Exhibit A (the "Note") and maturing in
        accordance with the provisions of Section 6 hereof, and
        containing such other terms and conditions, which are not
        inconsistent with the provisions of the Plan and the Stock
        Holding Policy, as the Committee shall determine in its sole and
        absolute discretion.

        SECTION 5.     Federal Income Tax Treatment of Loans.

             For federal income tax purposes, interest on Loans shall be
        imputed on any interest free Loan extended under the Plan.  A Key
        Employee shall be deemed to have paid the imputed interest to the
        Company and the Company shall be deemed to have paid said imputed
        interest back to the Key Employee as additional compensation.
        The deemed interest payment shall be taxable to the Company as
        income, and may be deductible to the Key Employee to the extent
        allowable under the rules relating to investment interest.  The
        deemed compensation payment to the Key Employee shall be taxable
        to the employee and deductible to the Company, but shall also be
        subject to employment taxes such as FICA and FUTA.

        SECTION 6.     Maturity of Loans.

             Each Loan to a Key Employee hereunder shall be due and
        payable on demand by the Company.  If no such demand is made,
        then each Loan shall mature and the principal thereof shall
        become due and payable in five equal annual installments from the
        payment of annual cash incentive compensation (referred to as
        bonus) to the Key Employee by the Company, beginning with the

                                        2PAGE
<PAGE>
        first such bonus payment to occur after the date of the Note
        evidencing the Loan, and on each of the next four bonus payment
        dates, provided that the Committee may, in its sole and absolute
        discretion, authorize such other maturity and repayment schedule
        as the Committee may determine.  Each Loan shall also become
        immediately due and payable in full, without demand, upon  the
        occurrence of any of the events set forth in the Note; provided
        that the Committee may, in its sole and absolute discretion,
        authorize an extension of the time for repayment of a Loan upon
        such terms and conditions as the Committee may determine.

        SECTION 7.     Amendment and Termination of the Plan.

             The Committee may from time to time alter or amend the Plan
        or the Stock Holding Policy in any respect, or terminate the Plan
        or the Stock Holding Policy at any time.  No such amendment or
        termination, however, shall alter or otherwise affect the terms
        and conditions of any Loan then outstanding to Key Employee
        without such Key Employee's written consent, except as otherwise
        provided herein or in the promissory note evidencing such Loan.

        SECTION 8.     Miscellaneous Provisions.

             (a)  No employee or other person shall have any claim or
        right to receive a Loan under the Plan, and no employee shall
        have any right to be retained in the employ of the Company due to
        his or her participation in the Plan.

             (b)  No Loan shall be made hereunder unless counsel for the
        Company shall be satisfied that such Loan will be in compliance
        with applicable federal, state and local laws.

             (c)  The expenses of the Plan shall be borne by the Company.

             (d)  The Plan shall be unfunded, and the Company shall not
        be required to establish any special or separate fund or to make
        any other segregation of assets to assure the making of any Loan
        under the Plan.

             (e)  Except as otherwise provided in Section 7 hereof, by
        accepting any Loan under the Plan, each Key Employee shall be
        conclusively deemed to have indicated his acceptance and
        ratification of, and consent to, any action taken under the Plan
        or the Stock Holding Policy by the Company, the Board of
        Directors of the Company or the Committee.

             (f)  The appropriate officers of the Company shall cause to
        be filed any reports, returns or other information regarding
        Loans hereunder, as may be required by any applicable statute,
        rule or regulation.

        SECTION 9.     Effective Date.

        $_________                                                       
                                                Dated:____________


             For value received, ________________, an individual whose
        residence is located at _______________________ (the "Employee"),
        hereby promises to pay to Thermo Sentron Inc. (the "Company"), or
        assigns, ON DEMAND, but in any case on or before [insert date
        which is the fifth anniversary of date of issuance] (the
        "Maturity Date"), the principal sum of [loan amount in words]
        ($_______), or such part thereof as then remains unpaid, without
        interest.  Principal shall be payable in lawful money of the
        United States of America, in immediately available funds, at the
        principal office of the Company or at such other place as the
        Company may designate from time to time in writing to the
        Employee. 

              Unless the Company has already made a demand for payment in
        full of this Note, the Employee agrees to repay the Company  an
        amount equal to 20% of the initial principal amount of the Note
        from the payment of annual cash incentive compensation (referred

                   Notes to Consolidated Financial Statements

    1.  Nature of Operations and Summary of Significant Accounting Policies

    Nature of Operations
        Thermo Sentron Inc. (the Company) designs, develops, manufactures,
    and sells high-speed precision-weighing and inspection equipment for
    industrial production and packaging lines. The Company serves two
    principal markets: packaged goods and bulk materials. Products for the
    packaged-goods market represent 37% of the Company's revenues and are
    sold to customers in the food-processing, pharmaceutical, mail-order, and
    other diverse industries. Products for the bulk-materials market
    represent 63% of the Company's revenues and are sold primarily to
    customers in the mining and material-processing industries, as well as to
    electric utilities, chemical, and other manufacturing companies. 

    Relationship with Thermedics Inc. and Thermo Electron Corporation
        On March 16, 1994, Thermedics Inc. (Thermedics) acquired the Ramsey
    Technology Inc. business (Ramsey, or the Predecessor) of Baker Hughes
    Incorporated (Baker Hughes) for a cash purchase price of $41.9 million.
    The Company was incorporated in November 1995 as a wholly owned
    subsidiary of Thermedics. On January 2, 1996, Thermedics transferred to
    the Company the assets, liabilities, and businesses of Ramsey and certain
    related companies in exchange for 7,000,000 shares of the Company's
    common stock. As of December 28, 1996, Thermedics owned 7,000,000 shares
    of the Company's common stock, representing 71% of such stock
    outstanding. Thermedics is a 55%-owned subsidiary of Thermo Electron
    Corporation (Thermo Electron). As of December 28, 1996, Thermo Electron
    owned 250,000 shares of the Company's common stock, representing 3% of
    such stock outstanding.

    Principles of Consolidation
        The accompanying financial statements include the accounts of the
    Company and its wholly owned subsidiaries. All material intercompany
    accounts and transactions have been eliminated.

    Fiscal Year
        The Company has adopted a fiscal year ending the Saturday nearest
    December 31. References to 1996 and 1995 are for the fiscal years ended
    December 28, 1996, and December 30, 1995, respectively. The accompanying
    financial statements also include the Company's financial results for the
    period from March 16, 1994, the date Ramsey was acquired by Thermedics,
    through December 31, 1994.

    Revenue Recognition

    Company provides a reserve for its estimate of warranty and installation
    costs at the time of shipment.

                   Notes to Consolidated Financial Statements

    1.  Nature of Operations and Summary of Significant Accounting Policies
        (continued)

    Stock-based Compensation Plans
        The Company applies Accounting Principles Board Opinion (APB) No. 25,
    "Accounting for Stock Issued to Employees" and related interpretations in
    accounting for its stock-based compensation plans (Note 5 ). Accordingly,
    no accounting  recognition is  given  to stock  options granted  at  fair
    market value  until  they are  exercised.  Upon   exercise,  net  proceeds,
    including tax benefits realized, are credited to equity.

    Income Taxes
        In the periods prior to its initial public offering, the Company was
    included in Thermedics' consolidated federal and certain state income tax
    returns. Subsequent to the Company's initial public offering in April
    1996, Thermedics' equity ownership of the company was reduced below 80%
    and, as a result, the Company is required to file its own federal income
    tax return.
        In accordance with Statement of Financial Accounting Standards (SFAS)
    No. 109, "Accounting for Income Taxes," the Company recognizes deferred
    income taxes based on the expected future tax consequences of differences
    between the financial statement basis and the tax basis of assets and
    liabilities, calculated using enacted tax rates in effect for the year in
    which the differences are expected to be reflected in the tax return.

    Earnings per Share
        Earnings per share has been computed based on the weighted average
    number of shares outstanding during the period. Pursuant to Securities
    and Exchange Commission requirements, earnings per share for the Company
    have been presented for all periods. Weighted average shares for all
    periods include the 7,000,000 shares issued to Thermedics in connection
    with the initial capitalization of the Company and, for periods prior to
    the Company's initial public offering, the effect of the assumed exercise
    of stock options issued within one year prior to the Company's initial
    public offering. Because the effect of the assumed exercise of stock
    options would be immaterial, they have been excluded from the calculation
    of weighted average shares subsequent to the Company's initial public
    offering.

    Cash and Cash Equivalents
        As of December 28, 1996, $24,732,000 of the Company's cash
    equivalents were invested in a repurchase agreement with Thermo Electron.
    Under this agreement, the Company in effect lends excess cash to Thermo
    Electron, which Thermo Electron collateralizes with investments
    principally consisting of U.S. government agency securities, corporate
    notes, commercial paper, money market funds, and other marketable
    securities, in the amount of at least 103% of such obligation. The
    Company's funds subject to the repurchase agreement are readily
    convertible into cash by the Company. The repurchase agreement earns a
    rate based on the 90-day Commercial Paper Composite Rate plus 25 basis

    Property, Plant, and Equipment
        The costs of additions and improvements are capitalized, while

    provides for depreciation and amortization using the straight-line and
    declining balance methods over the estimated useful lives of the property
    as follows: buildings, 30 years; machinery and equipment, 2 to 10 years;
    and leasehold improvements, the shorter of the term of the lease or the

                   Notes to Consolidated Financial Statements

    1.  Nature of Operations and Summary of Significant Accounting Policies
        (continued)

    Cost in Excess of Net Assets of Acquired Companies
        The excess of cost over the fair value of net assets of acquired
    companies is amortized using the straight-line method over 40 years.
    Accumulated amortization was $2,517,000 and $1,576,000 at year-end 1996
    and 1995, respectively. The Company assesses the future useful life of
    this asset whenever events or changes in circumstances indicate that the
    current useful life has diminished. The Company considers the future
    undiscounted cash flows of the acquired businesses in assessing the
    recoverability of this asset. If impairment has occurred, any excess of
    carrying value over fair value is recorded as a loss.

    Foreign Currency
        All assets and liabilities of the Company's foreign subsidiaries are
    translated at year-end exchange rates, and revenues and expenses are
    translated at average exchange rates for the year in accordance with SFAS
    No. 52, "Foreign Currency Translation." Resulting translation adjustments
    are reflected as a separate component of shareholders' investment titled
    "Cumulative translation adjustment." Foreign currency transaction gains
    are included in other income (expense) in the accompanying statement of
    income and are not material for 1996 and 1995. The Company recorded
    foreign currency transaction gains of $635,000 on the repayment of
    borrowings, denominated in U.S. dollars, for the period from March 16,
    1994, through December 31, 1994, which was included in other income
    (expense) in the accompanying statement of income.

    Fair Value of Financial Instruments
        The Company's financial instruments consist mainly of cash and cash
    equivalents, available-for-sale investments, accounts receivable, notes
    payable, accounts payable, and due to parent company and affiliated
    companies. Available-for-sale investments are carried at fair value in
    the accompanying balance sheet (Note 2). The fair values were determined
    based on quoted market prices. The carrying amounts of the Company's
    remaining financial instruments approximate fair value due to their
    short-term nature. 

    Use of Estimates
        The preparation of financial statements in conformity with generally
    accepted accounting principles requires management to make estimates and
    assumptions that affect the reported amounts of assets and liabilities,
    disclosure of contingent assets and liabilities at the date of the
    financial statements, and the reported amounts of revenues and expenses
    during the reporting period. Actual results could differ from those
    estimates.

    2.  Available-for-sale Investments

        In accordance with SFAS No. 115, "Accounting for Certain Investments
    in Debt and Equity Securities," the Company's debt securities are
    considered available-for-sale investments in the accompanying balance
    sheet and are carried at market value, with the difference between cost
    and market value, net of related tax effects, recorded currently as a
    component of shareholders' investment. The aggregate market value, cost
    basis, and gross unrealized gains of available-for-sale investments by
    major security type at December 28, 1996, are as follows:

                                             ======      ======      ======

        Available-for-sale investments in the accompanying 1996 balance sheet
    includes $5,045,000 with contractual maturities of one year or less and
    $1,549,000 with contractual maturities of more than one year through five
    years. Actual maturities may differ from contractual maturities as a
    result of the Company's intent to sell these securities prior to maturity
    and as a result of put and call options that enable either the Company,
    the issuer, or both to redeem these securities at an earlier date.
        The cost of available-for-sale investments that were sold was based
    on specific identification in determining realized gains of $37,000
    recorded in other income (expense) in the accompanying statement of
    income.

    3.  Acquisitions

        In April 1996, the Company purchased the assets of the solids
    flow-measurement product line of Endress + Hauser, Inc. (Endress +
    Hauser) for $4,437,000 in cash. The acquisition was financed with an
    advance from Thermo Electron that was repaid in April 1996. The product
    line purchase has been accounted for using the purchase method of
    accounting. Allocation of the purchase price was based on an estimate of
    the fair value of assets purchased.
        In January 1996, the Company acquired Hitech Electrocontrols Limited
    (Hitech), a U.K.-based manufacturer of metal-detection equipment and
    specialty checkweighing equipment for the baking industry, for $4,464,000
    in cash. The acquisition was financed with a credit facility, denominated
    in British pounds sterling, that was repaid in April 1996.

    3.  Acquisitions (continued)

        In July 1994, the Company acquired Tecno Europa Elettromeccanica
    S.r.1. (Tecno Europa), an Italian manufacturer of precision-weighing
    equipment with expertise in pharmaceutical applications. The Company
    acquired Tecno Europa for $945,000 in cash and the assumption of $605,000
    of debt.
        The acquisitions of Hitech and Tecno Europa have been accounted for
    using the purchase method of accounting, and their results of operations
    have been included in the accompanying financial statements from their
    respective dates of acquisition. The aggregate cost of Hitech and Tecno
    Europa exceeded the estimated fair value of the acquired net assets by
    $6,105,000, which is being amortized over 40 years. Allocation of the
    purchase price was based on an estimate of the fair value of the net
    assets acquired. Pro forma data is not presented since these acquisitions
    were not material to the Company's results of operations.

    4.  Common Stock

        In April 1996, the Company sold 2,875,000 shares of its common stock
    in an initial public offering at $16.00 per share, for net proceeds of
    $42,335,000. The Company used part of those proceeds to repay
    approximately $12,600,000 in advances and short-term borrowings from
    Thermo Electron and third parties (Note 3).
        At December 28, 1996, the Company had reserved 825,000 unissued
    shares of its common stock for possible issuance under stock-based
    compensation plans.

    5.  Employee Benefit Plans

    Stock-based Compensation Plans

    Stock Option Plans
    ------------------
        On January 30, 1996, the Company adopted a stock-based compensation
    plan for its key employees, directors, and others, which permits the
    grant of a variety of stock and stock-based awards as determined by the
    human resources committee of the Company's Board of Directors (the Board
    Committee), including restricted stock, stock options, stock bonus
    shares, or performance-based shares. To date, only nonqualified stock
    options have been awarded under this plan. The option recipients and the
    terms of options granted under this plan are determined by the Board
    Committee. Options granted through the date of the Company's initial
    public offering became exercisable on September 28, 1996. All options are
    subject to certain transfer restrictions and the right of the Company to
    repurchase shares issued upon exercise of the options at the exercise
    price, upon certain events. The restrictions and repurchase rights
    generally lapse ratably over a five to ten year period, depending on the
    term of the option, which generally ranges from ten to twelve years.
    Nonqualified stock options may be granted at any price determined by the
    Board Committee, although incentive stock options must be granted at not
    less than the fair market value of the Company's common stock on the date
    of grant. To date, all options have been granted at fair market value.
    The Company also has a directors' stock option plan, adopted on January
                                        14PAGE

    5.  Employee Benefit Plans (continued)

    30, 1996, that provides for the grant of stock options to outside
    directors pursuant to a formula approved by the Company's shareholders.
    Options granted under this plan have the same general terms as options
    granted under the stock-based compensation plan described above, except
    that the restrictions and repurchase rights generally lapse ratably over
    a four-year period and the option term is five years. In addition to
    participating in the Company's stock-based compensation plans, certain
    officers and key employees may also participate in the stock-based
    compensation plans of Thermo Electron and Thermedics.

    Employee Stock Purchase Program
    -------------------------------
       Substantially all of the Company's full-time U.S. employees are
    eligible to participate in an employee stock purchase program sponsored
    by Thermedics and Thermo Electron. Under this program, shares of
    Thermedics' and Thermo Electron's common stock can be purchased at the
    end of a 12-month period at 95% of the fair market value at the beginning
    of the period, and the shares purchased are subject to a six-month resale
    restriction. Prior to November 1, 1995, the applicable shares of common
    stock could be purchased at 85% of the fair market value at the beginning
    of the period, and the shares purchased were subject to a one-year resale
    restriction. Shares are purchased through payroll deductions of up to 10%
    of each participating employee's gross wages.

    Pro Forma Stock-based Compensation Expense
        In October 1995, the Financial Accounting Standards Board issued SFAS
    No. 123, "Accounting for Stock-Based Compensation," which sets forth a
    fair-value based method of recognizing stock-based compensation expense.
    As permitted by SFAS No. 123, the Company has elected to continue to
    apply APB No. 25 to account for its stock-based compensation plans. Had
    compensation cost for awards granted in 1996 under the Company's
    stock-based compensation plans been determined based on the fair value at
    the grant dates consistent with the method set forth under SFAS No. 123,
    the effect on the Company's net income and earnings per share would have
    been as follows:

    (In thousands except per share amounts)                             1996
    ------------------------------------------------------------------------
    Net income:

      Pro forma                                                       4,989
    Earnings per share:

        Pro forma compensation expense for options granted is reflected over
    the vesting period, therefore future pro forma compensation expense may
    be greater as additional options are granted.

                   Notes to Consolidated Financial Statements

    5.  Employee Benefit Plans (continued)

        The fair value of each option grant was estimated on the grant date
    using the Black-Scholes option-pricing model with the following
    weighted-average assumptions:
                                                                       1996
    -----------------------------------------------------------------------
    Volatility                                                          29%
    Risk-free interest rate                                            6.1%
    Expected life of options                                        8 years

        The Black-Scholes option-pricing model was developed for use in
    estimating the fair value of traded options which have no vesting
    restrictions and are fully transferable. In addition, option-pricing
    models require the input of highly subjective assumptions including
    expected stock price volatility. Because the Company's employee stock
    options have characteristics significantly different from those of traded
    options, and because changes in the subjective input assumptions can
    materially affect the fair value estimate, in management's opinion, the
    existing models do not necessarily provide a reliable single measure of
    the fair value of its employee stock options.

    Stock Option Activity
       A summary of the Company's stock option activity is as follows:

    income differs from the provision calculated by applying the statutory
    federal income tax rate of 35% to income before provision for income
    taxes due to the following:

        A provision has not been made for U.S. or additional foreign taxes on
    $3,655,000 of undistributed earnings of foreign subsidiaries that could
    be subject to taxation if remitted to the U.S. because the Company
    currently plans to keep these amounts permanently reinvested overseas.
    The Company believes that any additional U.S. tax liability due upon
    remittance of such earnings would be immaterial.

    7.   Commitments

        The Company leases portions of its office and operating facilities
    under various operating lease arrangements expiring between 1997 and
    2013. The accompanying statement of income includes expenses from
    operating leases of $1,759,000, $1,940,000, and $1,516,000 in 1996, 1995,
    and for the period from March 16, 1994, through December 31, 1994,
    respectively. Future minimum payments due under noncancelable operating
    leases at December 28, 1996, were $1,060,000 in 1997; $1,009,000 in 1998;
    $477,000 in 1999; $120,000 in 2000; $94,000 in 2001; and $754,000 in 2002
    and thereafter. Total future minimum lease payments of $3,514,000 have
    not been reduced by minimum sublease rentals of $264,000 due through 1999
    under noncancelable operating leases.

    8.  Related Party Transactions

    Corporate Services Agreement
        The Company and Thermo Electron have a corporate services agreement
    under which Thermo Electron's corporate staff provides certain
    administrative services, including certain legal advice and services,
    risk management, certain employee benefit administration, tax advice and
    preparation of tax returns, centralized cash management, and certain
    financial and other services, for which the Company pays Thermo Electron
    annually an amount equal to 1.0% of the Company's revenues. The Company
    paid an annual fee equal to 1.20% and 1.25% of the Company's revenues in
    1995 and 1994, respectively. The annual fee is reviewed and adjusted
    annually by mutual agreement of the parties. For these services, the
    Company was charged $700,000, $810,000, and $626,000 in 1996, 1995, and
    for the period from March 16, 1994, through December 31, 1994,
    respectively. The corporate services agreement is renewed annually but
    can be terminated upon 30 days' prior notice by the Company or upon the
    Company's withdrawal from the Thermo Electron Corporate Charter (the
    Thermo Electron Corporate Charter defines the relationship among Thermo
    Electron and its majority-owned subsidiaries). Management believes that
    the service fee charged by Thermo Electron is reasonable and that such
    fees are representative of the expenses the Company would have incurred
    on a stand-alone basis. For additional items such as employee benefit
    plans, insurance coverage, and other identifiable costs, Thermo Electron
    charges the Company based upon costs attributable to the Company.

    Other Related Party Transactions
        In connection with the acquisition of the Company by Thermedics, the
    Company ceased to distribute a line of alloy analyzers. In January 1995,
    this distributorship (TN Technologies or TN) was transferred to Thermo
    Instrument Systems Inc. (Thermo Instrument), a publicly traded,
    majority-owned subsidiary of Thermo Electron, for book value. 
        The Company acts as a distributor in Europe for process measurement
    instruments manufactured by TN. In 1996 and 1995, the Company purchased
    such products from TN for $563,000 and $998,000, respectively.
        In 1996 and 1995, the Company sold meters to TN pursuant to purchase
    orders resulting in revenues of $114,000 and $23,000, respectively.

    8.  Related Party Transactions (continued)

    Short-term Obligations
        In connection with the acquisition of the Company by Thermedics, the
    Company's foreign subsidiaries borrowed $6,325,000 from Thermedics at
    interest rates ranging from 6.0% to 9.5%. Prior to December 31, 1994, the
    debt with Thermedics was repaid and refinanced with third parties in the
    local currency of the foreign subsidiaries, resulting in an exchange gain
    of $635,000. During the period from March 16, 1994, through December 31,
    1994, the Company recorded interest expense of $415,000 relating to the
    debt with Thermedics.

    Repurchase Agreement
        The Company invests excess cash in a repurchase agreement with
    Thermo Electron as discussed in Note 1.

    9.  Short-term Obligations

        Notes payable at December 30, 1995, includes $1,889,000 principal
    amount of a 12.6% note payable denominated in Italian lira. The Company
    repaid the obligation in 1996.
        The Company's foreign subsidiaries have lines of credit outstanding
    of $3,500,000 and $6,001,000 as of year-end 1996 and 1995, respectively.
    The weighted average interest rate for these borrowings was 6.4% and 7.8%
    as of year-end 1996 and 1995, respectively. Unused lines of credit were
    $9,690,000 as of December 28, 1996. Amounts borrowed under these
    arrangements are included in notes payable in the accompanying balance
    sheet.

                    Report Of Independent Public Accountants


    To the Shareholders and Board of Directors of Thermo Sentron Inc.:

        We have audited the accompanying consolidated balance sheet of Thermo
    Sentron Inc. (a Delaware corporation and 71%-owned subsidiary of
    Thermedics Inc.) and its subsidiaries as of December 28, 1996, and
    December 30, 1995, and the related consolidated statements of income,
    shareholders' investment, and cash flows for the years ended December 28,
    1996, and December 30, 1995, and for the period from March 16, 1994,
    through December 31, 1994. These consolidated financial statements are
    the responsibility of the Company's management. Our responsibility is to
    express an opinion on these consolidated financial statements based on
    our audits.
        We conducted our audits in accordance with generally accepted
    auditing standards. Those standards require that we plan and perform the
    audit to obtain reasonable assurance about whether the consolidated
    financial statements are free of material misstatement. An audit includes
    examining, on a test basis, evidence supporting the amounts and
    disclosures in the financial statements. An audit also includes assessing
    the accounting principles used and significant estimates made by
    management, as well as evaluating the overall financial statement
    presentation. We believe that our audits provide a reasonable basis for
    our opinion.
        In our opinion, the consolidated financial statements referred to
    above present fairly, in all material respects, the financial position of
    Thermo Sentron Inc. and its subsidiaries as of December 28, 1996, and
    December 30, 1995, and the results of their operations and their cash
    flows for the years ended December 28, 1996, and December 30, 1995, and
    for the period from March 16, 1994, through December 31, 1994, in
    conformity with generally accepted accounting principles.

                  Financial Condition and Results of Operations

        Forward-looking statements, within the meaning of Section 21E of the
    Securities Exchange Act of 1934, are made throughout this Management's
    Discussion and Analysis of Financial Condition and Results of Operations.
    For this purpose, any statements contained herein that are not statements
    of historical fact may be deemed to be forward-looking statements.
    Without limiting the foregoing, the words "believes," "anticipates,"
    "plans," "expects," "seeks," "estimates," and similar expressions are
    intended to identify forward-looking statements. There are a number of
    important factors that could cause the results of the Company to differ
    materially from those indicated by such forward-looking statements,
    including those detailed immediately after this Management's Discussion
    and Analysis of Financial Condition and Results of Operations under the
    caption "Forward-looking Statements."

    Overview

        The Company designs, develops, manufactures, and sells high-speed
    precision-weighing and inspection equipment for industrial production and
    packaging lines. The Company serves two principal markets: packaged goods
    and bulk materials. The Company's products for the packaged-goods market
    include a broad line of checkweighing equipment and metal detectors that
    can be integrated at various stages in production lines for process
    control and quality assurance. These products are sold to customers in
    the food-processing, pharmaceutical, mail-order, and other diverse
    industries. The Company's bulk-materials product line includes
    conveyor-belt scales, solid level-measurement and conveyor-monitoring
    devices, and sampling systems. These products are sold primarily to
    customers in the mining and material-processing industries, as well as to
    electric utilities, chemical, and other manufacturing companies.
        Prior to March 16, 1994, the Company was operated as a wholly owned
    subsidiary of Baker Hughes Incorporated (Baker Hughes). During the time
    that Baker Hughes owned the Company, the Company's European subsidiaries
    had a high cost structure relative to their sales. This high cost
    structure resulted in losses at the Company's European subsidiaries which
    could not be offset with income from the United States and other sources
    for tax purposes. Consequently, the Company's tax rate was significantly
    higher than statutory rates. Shortly after its purchase by Thermedics
    Inc. (Thermedics) in March 1994, the Company's management initiated a
    restructuring program to reduce its costs. This restructuring involved
    reducing the Company's manufacturing overhead through the outsourcing of
    noncritical manufacturing, as well as staff reductions, particularly at
    its European subsidiaries. In 1996 and 1995, the Company's foreign
    operations contributed income before provision for taxes at levels
    comparable to those of the Company's domestic operations (Note 10). In
    connection with the acquisition of the Company by Thermedics, the Company
    ceased to distribute a line of alloy analyzers (the TN product line). In
    January 1995, this distributorship was transferred to Thermo Instrument
    Systems Inc. (Thermo Instrument), a majority-owned subsidiary of Thermo
    Electron Corporation (Thermo Electron), at book value. The Company
    recorded $3.1 million of revenues from the TN product line in the twelve
    months ended December 31, 1994.

                     Management's Discussion And Analysis of

    Overview (continued)

        A portion of the Company's revenues are generated from large orders
    for the Company's sampling systems. This equipment has a high percentage
    of subcontracted costs, particularly for steel and steel fabrication,
    which results in lower gross profit margins than for the Company's other
    products. The timing of the sales of this equipment can lead to
    variability in the Company's quarterly revenues and income. In addition,
    over 60% of the Company's revenues in 1996 were derived from sales of
    products outside the United States, through export sales and sales by the
    Company's foreign subsidiaries. The Company expects an increase in the
    percentage of its revenues derived from international operations.
    Although the Company seeks to charge its customers in the same currency
    as its operating costs, the Company's financial performance and
    competitive position can be affected by currency exchange rate
    fluctuations affecting the relationship between the U.S. dollar and
    foreign currencies.

    Results of Operations

    1996 Compared With 1995
        Revenues were $70.0 million in 1996, compared with $67.5 million in
    1995, an increase of 4%. The increase in revenues primarily reflects the
    inclusion of $6.7 million in revenues from Hitech Electrocontrols Limited
    (Hitech), acquired in January 1996, and the solids flow-measurement
    product line of Endress + Hauser (Endress + Hauser), purchased in April
    1996. This increase was offset in part by a $3.2 million decrease in U.S.
    revenues from existing product lines. U.S. revenues decreased due to
    lower demand resulting from a reduction in capital spending by major food
    suppliers, caused by higher grain prices and breakfast cereal price wars,
    and the inclusion of $1.8 million in revenues in 1995 from the sale of a
    large sampling system to a customer in Taiwan.
        The gross profit margin increased to 40% in 1996 from 39% in 1995,
    primarily due to sales from the higher-margin Endress + Hauser product
    line.
        Selling, general, and administrative expenses as a percentage of
    revenues increased to 27% in 1996 from 26% in 1995, primarily due to
    increased selling and marketing expenses for newly introduced products
    and the Endress + Hauser products. Research and development expenses were
    relatively unchanged at 2.7% of revenues in 1996 and 2.8% of revenues in
    1995.
        Interest income increased to $1.5 million in 1996 from $0.2 million
    in 1995, primarily due to interest earned on the invested proceeds from
    the Company's April 1996 initial public offering of common stock       
    (Note 4). Interest expense decreased to $0.6 million in 1996 from $0.9
    million in 1995 due to the repayment of a note payable and a reduction in
    short-term borrowings. Interest expense includes interest on borrowings
    at the Company's foreign subsidiaries and on a credit facility
    denominated in British pounds sterling.
        The effective tax rate was 38% in 1996, compared with 40% in 1995.
    The effective tax rates exceed the statutory federal income tax rate due

                  Financial Condition and Results of Operations

    1996 Compared With 1995 (continued)
    primarily to the impact of state income taxes and foreign tax rate and
    tax law differences. 

    1995 Compared With 1994
        Revenues were $67.5 million in 1995, compared with $61.1 million in
    the twelve months ended December 31, 1994 (Note 11), an increase of $6.4
    million or 10%. Revenues increased $2.8 million primarily due to the
    inclusion of revenues for the entire 1995 period from Tecno Europa,
    acquired in July 1994. In addition, revenues increased in 1995 as a
    result of $3.6 million in higher sales of the Company's packaged-goods
    products due to increased demand, the inclusion of a $1.8 million
    sampling system order from a customer in Taiwan, and a $1.1 million
    increase due to the weakness of the U.S. dollar relative to foreign
    currencies in countries where the Company operates. These increases were
    partially offset by a $3.1 million decline in revenues in 1995 due to the
    transfer of the TN product line.
        The gross profit margin increased to 39% in 1995 from 34% in the
    twelve months ended December 31, 1994, primarily due to a reduction in
    workforce and other cost savings as a result of the restructuring of the
    Company's operations during 1994, after the Company was acquired by
    Thermedics.
        Selling, general, and administrative expenses as a percentage of
    revenues decreased to 26% in 1995 from 28% in the twelve months ended
    December 31, 1994, due to the increased revenues in 1995 and a reduction
    in general and administrative expenses as part of the restructuring of
    the Company's operations in 1994. These decreases were offset in part by
    an increase in amortization of cost in excess of net assets of acquired
    companies during 1995 as a result of the acquisition of the Company by
    Thermedics. Research and development expenses as a percentage of revenues
    increased to 2.8% in 1995 from 2.5% in the twelve months ended December
    31, 1994, due to the higher rate of research and development expenditures
    at Tecno Europa.
        Interest expense increased to $0.9 million in 1995 from $0.6 million
    in the twelve months ended December 31, 1994. Interest expense includes
    interest on borrowings at the Company's foreign subsidiaries incurred to
    refinance intercompany borrowings from Thermedics, which were made in
    connection with the acquisition of the Company by Thermedics. Interest
    expense also includes borrowings related to the purchase of Tecno Europa
    in 1994. The increase in interest expense in 1995 results from a full
    year of interest expense on the foreign borrowings related to the
    acquisition of the Company, offset in part by lower outstanding
    borrowings.
        Other income of $0.6 million in the twelve months ended December 31,
    1994, represents a foreign-exchange gain on the repayment of intercompany
    borrowings from Thermedics.
        The effective tax rate was 40% in 1995, compared with 68% in the
    twelve months ended December 31, 1994. The effective tax rates exceed the
    statutory federal income tax rate primarily due to the impact of state
    income taxes in 1995, and to the inability to provide a tax benefit on
    losses incurred at certain foreign subsidiaries, primarily in Germany,

    1995 Compared With 1994 (continued)
    France, and Italy, and the impact of state income taxes in 1994. As
    discussed in "Overview," the Company experienced losses at several
    foreign subsidiaries through 1994 as a result of a historically high cost
    structure. The Company took measures to reduce these losses following the
    1994 acquisition of the Company by Thermedics.

    Liquidity and Capital Resources

        Consolidated working capital was $41.4 million at December 28, 1996,
    compared with negative $0.9 million at December 30, 1995. Included in
    working capital are cash, cash equivalents, and available-for-sale
    investments of $34.8 million at December 28, 1996, compared with $3.0
    million at December 30, 1995.
        During 1996, operating activities provided cash of $3.5 million, net
    of $3.8 million of cash used to fund an increase in accounts receivable
    during the year, primarily as a result of unusually high U.S. sales in
    December 1996. A high level of cash receipts in December 1995 resulted in
    lower outstanding accounts receivable at year-end 1995.
        During 1996, the Company's primary investing activities, excluding
    purchases, sales, and maturities of available-for-sale investments,
    included acquisitions and capital expenditures. The Company acquired
    Hitech and the solids flow-measurement product line of Endress + Hauser
    in 1996 for approximately $8.9 million in cash (Note 3). The Hitech
    acquisition was financed with a credit facility denominated in British
    pounds sterling, and the product line purchase was financed with an
    advance from Thermo Electron. Both were repaid in April 1996 with
    proceeds received from the issuance of Company common stock. In March
    1997, the Company acquired substantially all of the assets of RCC
    Industrial Electronics Pty. Ltd., a manufacturer of in-motion
    checkweighers for the food and pharmaceutical industries, for
    approximately $1.0 million in cash and the assumption of certain
    liabilities. The Company expended $0.9 million for purchases of property,
    plant, and equipment in 1996, and plans to make capital expenditures of
    approximately $1.1 million in 1997.
        In April 1996, the Company sold 2,875,000 shares of its common stock
    in an initial public offering, for net proceeds of $42.3 million (Note
    4). The Company used part of the proceeds to repay approximately $12.6
    million in short-term borrowings from Thermo Electron and third parties.
        Although the Company expects to have positive cash flow from its
    existing operations, the Company may require significant amounts of cash
    for the acquisition of complementary businesses. The Company expects that
    it will finance any such acquisition through a combination of internal
    funds, additional debt or equity financing from the capital markets, or
    short-term borrowings from Thermedics or Thermo Electron, although it has
    no agreement with these companies to ensure that funds will be available
    on acceptable terms or at all. The Company believes that its existing
    resources are sufficient to meet the capital requirements of its existing
    businesses for the foreseeable future.

    Securities Litigation Reform Act of 1995, the Company wishes to caution
    readers that the following important factors, among others, in some cases
    have affected, and in the future could affect, the Company's actual
    results and could cause its actual results in 1997 and beyond to differ
    materially from those expressed in any forward-looking statements made
    by, or on behalf of, the Company.
        Risks Associated With Acquisition Strategy. The Company's strategy
    includes the acquisition of businesses and technologies that complement
    or augment the Company's existing product lines. Promising acquisitions
    are difficult to identify and complete for a number of reasons, including
    competition among prospective buyers and the need for regulatory
    approval, including antitrust approvals. There can be no assurance that
    the Company will be able to complete future acquisitions or that the
    Company will be able to successfully integrate any acquired business. In
    order to finance such acquisitions, it may be necessary for the Company
    to raise additional funds through public or private financings. Any
    equity or debt financing, if available at all, may be on terms that are
    not favorable to the Company and, in the case of equity financing, may
    result in dilution to the Company's stockholders.
        International Operations. Sales outside the United States accounted
    for more than 57% of the Company's total revenues in each of the last
    three years. The Company intends to continue to expand its presence in
    international markets. International revenues are subject to a number of
    risks, including the following: agreements may be difficult to enforce
    and receivables difficult to collect through a foreign country's legal
    system; foreign customers may have longer payment cycles; foreign
    countries may impose additional withholding taxes or otherwise tax the
    Company's foreign income, impose tariffs, or adopt other restrictions on
    foreign trade; fluctuations in exchange rates may affect product demand
    and adversely affect the profitability in U.S. dollars of products and
    services provided by the Company in foreign markets where payment for the
    Company's products and services is made in the local currency; U.S.
    export licenses may be difficult to obtain; and the protection of
    intellectual property in foreign countries may be more difficult to
    enforce. There can be no assurance that any of these factors will not
    have a material adverse effect on the Company's business and results of
    operations.
        Government Regulations and Approvals. The market for certain of the
    Company's products, both in the United States and abroad, is subject to
    or influenced by various domestic and foreign clean air and consumer
    protection laws. The Company designs, develops, and markets its products
    to meet customer needs created by existing and anticipated regulations,
    and any changes in these regulations may adversely affect consumer demand
    for the Company's products. In addition, the marketing of certain of the
    Company's products is dependent upon the receipt of regulatory and other
    approvals, including industry association approvals of the design,
    construction, and accuracy of the Company's products. Delays in
    obtaining, or the failure to obtain, any such approvals could have a
    material adverse effect on the Company's business and results of
    operations.
        Competition. The Company encounters and expects to continue to
    encounter intense competition in the sale of its products. The Company

    believes that the principal competitive factors affecting the market for
    precision-weighing and inspection equipment include customer service and
    support, quality and reliability, price, accuracy, ease of use,
    distribution channels, technical features, compatibility with customers'
    manufacturing processes, and regulatory approvals. Certain of the
    Company's competitors have greater resources, manufacturing and marketing
    capabilities, technical staff, and production facilities than those of
    the Company. As a result, they may be able to adapt more quickly to new
    or emerging technologies and changes in customer requirements, or to
    devote greater resources to the promotion and sale of their products than
    can the Company. Competition could increase if new companies enter the
    market or if existing competitors expand their product lines.
        Technological Change and New Products. The market for precision-
    weighing and inspection equipment is characterized by changing
    technology, evolving industry standards, and new product introductions.
    The Company's future success will depend in part upon its ability to
    enhance its existing products and to develop and introduce new products
    and technologies to meet changing customer requirements. The Company is
    currently devoting significant resources to enhancing its existing
    products and developing new products and technologies. There can be no
    assurance that the Company will successfully complete the enhancement and
    development of these products in a timely fashion or that the Company's
    current or future products will satisfy the needs of the
    precision-weighing and inspection equipment market.
        Potential Fluctuations in Quarterly Performance. The Company's
    quarterly operating results may vary significantly depending on a number
    of factors, including the size, timing, and shipment of individual
    orders, seasonality of revenue, foreign currency exchange rates, the mix
    of products sold, and general economic conditions. Because the Company's
    operating expenses are based on anticipated revenue levels and a high
    percentage of the Company's expenses are fixed for the short term, a
    small variation in the timing of recognition of revenue can cause
    significant variations in operating results from quarter to quarter.

 (a) On March 16, 1994, Thermedics acquired the Predecessor from Baker Hughes.
     Periods prior to March 16, 1994, represent the results of Ramsey as
     included in Baker Hughes' financial statements. Periods subsequent to March
     15, 1994, represent the results of Ramsey as included in Thermedics'
     consolidated financial statements. The principal difference in the basis of
     accounting between the Predecessor and the Company relates to the cost in
     excess of net assets of acquired companies, the amortization of which
     approximates $860,000 per year.
 (b) Includes the net proceeds of the Company's initial public offering in April
     1996.
