                           BARRINGER TECHNOLOGIES INC.

     This Prospectus  relates to 362,075 shares of common stock, par value $0.01
per share ("Common  Stock"),  of Barringer  Technologies  Inc. (the  "Company"),
which are issuable upon the exercise of 1,448,300 Common Stock Purchase Warrants
(the "Warrants") of the Company. The Warrants are exercisable until November 12,
1999 and entitle  the holder  thereof to  purchase  one-quarter  of one share of
Common Stock at a price of $9.847 per share.  The exercise price of the Warrants
and the number of shares  issuable  upon exercise of the Warrants are subject to
adjustment  under  certain  circumstances.  The Warrants are  redeemable  by the
Company  for  $0.25  per   Warrant   (subject  to   adjustment   under   certain
circumstances), upon not less than 30 days' prior written notice, if the closing
bid price of the Common Stock  averages in excess of 200% of the exercise  price
of the Warrants for a period of 30 days ending within 15 days of the  redemption
notice date.

     If the Warrants are exercised in full,  the Company would receive  proceeds
of  approximately  $3.6  million  (prior to the  deduction  of fees and expenses
payable in connection with this Offering).  Other than the proceeds  received by
the Company from the exercise of the Warrants,  the Company will not receive any
of the proceeds  from the sale of the Common Stock offered  hereby.  The Company
estimates that its expenses in connection with this offering of the Common Stock
(the "Offering") will be approximately $15,000.

     The Common  Stock and the  Warrants  are  included  in the Nasdaq  National
Market under ther symbols "BARR" and "BARRW",  respectively. On May 1, 1998, the
last sale price of the Common  Stock as reported on the Nasdaq  National  Market

                                  RISK FACTORS

     The Common Stock offered hereby involves a high degree of risk. In addition
to the  other  information  contained  in this  Prospectus  or  incorporated  by
reference,  the  following  risk  factors  should  be  considered  carefully  in
evaluating  the  Company,  its business  and an  investment  in the Common Stock
offered hereby.

Dependence on Government Procurement Policies

The Company's  business is dependent upon purchases of IONSCAN(R)s by government
agencies.  Budgetary allocations for detection equipment are dependent, in part,
upon  government  policies  that  fluctuate  from  time to time in  response  to
political and other factors,  including the public's perception of the threat of
airline   bombings  and  other  terrorist  acts.  The  Company  expects  that  a
substantial  portion of current and anticipated  purchases of advanced detection
equipment  will  continue to be made by government  agencies  with  appropriated
funds.  For  instance,  sales  to FAA  constituted  approximately  14.8%  of the
Company's revenues for the fiscal year ended December 31, 1997.

A  reduction  of  funding  for  security  efforts  or  drug  interdiction  could
materially and adversely affect the Company's business,  financial condition and
results of  operations.  There can be no assurance that funding for the purchase
of such  equipment  will be  continued  or as to the  level of such  funding.  A
substantial  amount of the  funds  appropriated  to date  have been and  amounts
appropriated  in the  future  will  continue  to be used to  purchase  equipment
utilizing other technologies,  such as enhanced x-ray, computer aided tomography
("CATSCAN") and other bulk imaging  technologies.  Accordingly,  there can be no
assurance  as to the amount  that will  ultimately  be spent on the  purchase of
trace particle detection  equipment or as to the number of IONSCAN(R)s that will
actually be purchased. In addition, there can be no assurance that the Company's
products will meet any  certification or other  requirements that may be adopted
by any government agencies.

Dependence on Large Orders; Customer Concentrations

In any given fiscal year, the Company's revenues have principally consisted, and
the Company  believes  will  continue to consist,  of large  orders for multiple
IONSCAN(R)s from a limited number of customers. While the number and identity of
the  Company's  customers  may vary  from  period  to  period,  the  Company  is
nevertheless  dependent upon these multiple orders for a substantial  portion of
its  revenues.  There can be no  assurance  that the  Company  will  obtain such
multiple orders on a consistent basis.  During the year ended December 31, 1997,
approximately  $8.3 million,  or 36.7%, of the Company's revenues were generated
from  sales to the  Company's  three  largest  customers.  During the year ended
December 31, 1996,  revenues from the Company's  three  largest  customers  were
approximately $2.8 million, or 39.3%, of the Company's  revenues.  A significant
portion of the Company's anticipated future revenues are expected to result from
orders from the FAA.  The  Company's  inability  to obtain  sufficient  multiple
orders or to expand its customer  base could have a material  adverse  effect on
the Company's business, financial condition and results of operations.

Dependence on IONSCAN(R) and Market Acceptance

The  Company  derives  substantially  all of  its  revenues  from  the  sale  of
IONSCAN(R)s.  There can be no assurance  that markets for the  IONSCAN(R) or the
Company's  other current or future  products will develop as the Company expects
or that the  Company  will be able to  capitalize  on such  market  development.
Similarly,  there can be no  assurance  that any markets that do develop will be
sustained.

Dependence on New Product Development; Technological Advancement

The Company's  success is dependent  upon its ability to continue to enhance the
IONSCAN(R)  and to  develop  or  acquire  new  products  and  technologies  that
incorporate  technological  advances, keep pace with evolving industry standards
and  respond to  changing  customer  requirements.  If the  Company is

<PAGE>

unable to develop and introduce new products or  enhancements in a timely manner
in  response  to  changing  market  conditions  or  customer  requirements,  the
Company's  business,  financial  condition  and results of  operations  would be
materially and adversely affected.

In  addition,  from  time  to time  the  Company  or its  present  or  potential
competitors may introduce new products,  capabilities or technologies  that have
the  potential  to replace,  shorten the life spans of, or render  obsolete  the
Company's existing products.  There can be no assurance that the Company will be
successful in convincing  potential customers that the IONSCAN(R) is superior to
such other  systems or  products,  that new systems with  comparable  or greater
performance,  lower  prices  and  faster or  equivalent  throughput  will not be
introduced,  or that, if such products are introduced,  customers will not delay
or cancel  existing  or  future  orders  for the  IONSCAN(R).  Announcements  of
currently  planned or other new  products  may cause  customers  to delay  their
purchasing decisions in anticipation of such products,  as occurred in late 1994
when the Company  introduced the Model 400 IONSCAN(R).  Such delays could have a
material  adverse  effect on the  Company's  business,  financial  condition and
results of operations.

Limited Proprietary Technology

Certain of the technology used in the IONSCAN(R) is licensed by the Company from
the Canadian  government  pursuant to a license  agreement that expires in March
1999,  subject to the Company's right to extend on a year-to-year  basis through
March 2009.  While the Company  holds  patents  relating to certain  components,
systems and  techniques  used in the IONSCAN(R) and while certain other elements
of the  IONSCAN(R)  are protected by other  intellectual  property  rights,  the
Company has no comprehensive patent or similar exclusive  intellectual  property
right  covering the  IONSCAN(R)  in its  entirety.  In  addition,  the basic IMS
technology used by the Company is not proprietary and is available in the public
domain.  Accordingly,  present and  potential  competitors  could use such basic
technology to duplicate the performance of the IONSCAN(R).

Fluctuations in Operating Results

The Company's past operating results have been, and its future operating results
will be, subject to fluctuations resulting from a number of factors,  including:
the timing and size of orders from, and shipments to, major customers; budgeting
and purchasing  cycles of its customers;  delays in product  shipments caused by
customer  requirements  or the inability of customers to accept  shipments;  the
timing  of  enhancements  to the  IONSCAN(R)  by  the  Company  or new  products
introduced by the Company or its competitors; changes in pricing policies by the
Company,  its competitors or suppliers,  including possible decreases in average
selling  prices of the  IONSCAN(R)  in response to  competitive  pressures;  the
proportion of revenues derived from  competitive bid processes;  the mix between
sales to domestic and  international  customers;  market  acceptance of enhanced
versions of the IONSCAN(R);  the  availability  and cost of key components;  the
availability of  manufacturing  capacity;  and  fluctuations in general economic
conditions. The Company also may choose to reduce prices or to increase spending
in response to competition or to pursue new market opportunities,  and may incur
significant  charges or expenses in connection with  acquisitions  and strategic
relationships,  all of which may have a material adverse effect on the Company's
business,  financial condition and results of operations. The Company's revenues
in any period are  substantially  derived from sales of IONSCAN(R)s to a limited
number of customers and such revenues are recognized upon shipment. As a result,
variations  in the  number of orders or the  timing of  shipments  may cause the
Company's quarterly and annual operating results to vary substantially.

Moreover, government agencies and certain other customers expend unused budgeted
funds at the end of their respective  fiscal years,  causing the Company's sales
to be higher  during such  periods.  Because the  Company  generally  recognizes
substantially  all of the  revenue  from a sale upon  shipment,  and because the
recognition  of  revenue  from  the  sale  of  relatively  few  IONSCAN(R)s  may
substantially  impact the Company's  profitability during any period, the impact
of these budgetary considerations on the delivery date of a relatively few units
could   significantly   affect  the   Company's   quarterly   results   and  the
predictability of such quarterly results.

<PAGE>

Competition

The  Company  competes  with other  entities,  including  Intelligent  Detection
Systems Inc., Ion Track Instruments Inc. and Thermedics Detection Inc., a number
of which have  significantly  greater  financial,  marketing and other resources
than the Company. Principal competitive factors include selectivity (the ability
of  an  instrument  to  identify  the  presence  of  a  particular   substance),
sensitivity  (the  ability  of  an  instrument  to  detect  small  amounts  of a
particular substance), false alarm rate, price, marketing, ease of use and speed
of analysis. There can be no assurance that the Company will be able to continue
to compete  successfully  with its  competitors  or be able to compete  with new
market entrants or in new markets that may develop.

The Company competes for government  expenditures with equipment  manufacturers,
such as InVision  Technologies,  Inc. and Vivid  Technologies,  Inc.,  utilizing
other types of detection  technologies,  including  enhanced x-ray,  CATSCAN and
other bulk  imaging  technologies,  as well as with  manufacturers  of other IMS
equipment and manufacturers  using other trace particle detection  technologies,
such as gas chromatography and chemiluminescence.

The  Company  also  competes  with the use of canines to locate the  presence of
explosives or drugs.

As a result of recent  government  initiatives,  the  Company  anticipates  that
additional technologies,  including improved IMS technologies, will be developed
and that new competitors  will enter the Company's  markets.  The failure of the
Company to develop improvements or otherwise successfully compete in its markets
would  have a  material  adverse  effect on the  Company's  business,  financial
condition and results of operations.

Lengthy Sales Cycle

The Company's  sales  process is often  protracted  due to the lengthy  approval
processes that typically accompany government expenditures. Typically, six to 12
months may elapse between a new customer's  initial evaluation of the IONSCAN(R)
and the placement of an order.

International Business;  Risk of Change in Foreign Regulations;  Fluctuations in
Exchange Rates

The  Company  markets  its  products  to  customers  outside  of the  U.S.  and,
accordingly,  is  exposed  to the risks of  international  business  operations,
including  unexpected changes in foreign and domestic  regulatory  requirements,
possible foreign currency controls, uncertain ability to protect and utilize its
intellectual   property  in  foreign   jurisdictions,   currency  exchange  rate
fluctuations  or  devaluations,  tariffs  or  other  barriers,  difficulties  in
staffing and managing foreign operations, difficulties in obtaining and managing
vendors  and   distributors   and   potentially   negative   tax   consequences.
International  sales are subject to certain  inherent risks including  embargoes
and other trade  barriers,  staffing  and  operating  foreign  sales and service
operations and collecting  accounts  receivable.  The Company is also subject to
risks  associated  with  regulations  relating  to the import and export of high
technology  products.  The Company  cannot predict  whether,  or to what extent,
quotas,  duties,  taxes or other charges or restrictions upon the importation or
exportation  of the Company's  products in the future will be implemented by the
U.S. or any other  country.  There can be no assurance that any of these factors
will not have a material  adverse  effect on the Company's  business,  financial
condition and results of operations.

A portion of the  Company's  revenues and expenses  are  denominated  in foreign
currencies.  Fluctuations in currency  exchange rates could adversely affect the
Company's  profitability  and  could  cause  the  Company's  products  to become
relatively more expensive to customers in a particular country, leading to fewer
sales or reduced  selling  prices in that country.  As a result,  the Company is
exposed to a certain  degree of exchange rate risk.  The Company  generally does
not hedge its foreign  exchange  exposure.  There can be no  assurance  that the
Company  will not  experience  material  losses  in the  future  as a result 

<PAGE>

of  currency  fluctuations  or that any  such  losses  will not have a  material
adverse  effect on the Company's  business,  financial  condition and results of
operations.

Dependence on Limited Number of Suppliers

Certain key components used in the Company's  products have been designed by the
Company,  are  manufactured  pursuant to the  Company's  specifications  and are
currently purchased from only one or a limited number of suppliers.  The Company
currently does not have long-term agreements with these suppliers.  Moreover, in
view of the high cost of many of these components, the Company does not maintain
significant inventories of some necessary components.  Recently, the Company has
significantly  increased  its  purchases of certain  components to meet expected
demand for the IONSCAN(R).  As a result, in certain  circumstances,  the Company
has had to enter into new supply relationships in order to satisfy its increased
demand  for  components  and  may be  required  to do so in the  future.  If the
Company's  suppliers were to experience  financial,  operational,  production or
quality assurance difficulties, the supply of components to the Company would be
reduced or interrupted.  In the event that a supplier were to cease  operations,
discontinue  production  of a component or withhold  supply for any reason,  the
Company might be unable to acquire certain components from alternative  sources,
to find alternative  third-party  manufacturers or sub-assemblers,  or to obtain
sufficient  quantities  of certain  components,  which could result in delays or
interruptions in product shipments,  and could have a material adverse effect on
the Company's business, financial condition and results of operations.

Ability to Manage Rapid Growth

The  Company  has  rapidly  expanded  its  business  operations  as a result  of
increased demand for the IONSCAN(R), which has placed significant demands on the
Company's manufacturing, management and working capital resources and operating,
management and financial  control systems.  Failure to maintain needed resources
or to enhance the Company's operating,  management and financial control systems
as and when necessary,  or difficulties  encountered  during such  enhancements,
could  have a  material  adverse  effect on the  Company's  business,  financial
condition  and results of  operations.  The  Company's  future  growth also will
depend on its  ability to continue  to improve  and expand its  engineering  and
technical  resources  and to attract,  retain and  motivate key  personnel.  The
failure of the Company to increase its revenues  sufficiently  to compensate for
increased expenses resulting from current or future expansion,  or the Company's
failure to otherwise adequately manage the growth of its business,  would have a
material  adverse  effect on the  Company's  business,  financial  condition and
results of operations.  Further,  there can be no assurance that the Company can
sustain its recent rapid growth.

Risks Associated with Acquisition Strategy

An element of the Company's strategy is to seek acquisition  partners that would
complement  the  Company's  existing  product  offerings,   augment  its  market
coverage,  enhance its  technological  capabilities  or  otherwise  offer growth
opportunities.  Although the Company has no present understandings,  commitments
or agreements with respect to any material acquisition of any business, products
or technologies,  the Company may make such  acquisitions in the future.  Future
acquisitions  by the Company could result in potentially  dilutive  issuances of
equity   securities,   the  incurrence  of  debt  and  contingent   liabilities,
amortization  expenses relating to goodwill and other intangible assets, and the
incurrence of significant charges or expenses relating to any acquired business,
any of which could  materially  and  adversely  affect the  Company's  business,
financial  condition and results of  operations.  Acquisitions  entail  numerous
risks,  including  difficulties  in the  assimilation  of  acquired  businesses,
products  and  technologies,  diversion  of  management's  attention  from other
business  concerns,  risks of  entering  markets in which the  Company has no or
limited  prior  experience  and  potential  loss of key  employees  of  acquired
organizations.  The Company's  management has limited experience in assimilating
acquired  organizations.  No  assurance  can be given as to the  ability  of the
Company to integrate  successfully  any  businesses,  products,  technologies or
personnel that might be acquired in the future, and

<PAGE>

the failure of the Company to do so could have a material  adverse effect on the
Company's business, financial condition and results of operations.

Retention of and Dependence on Key Personnel

The  Company's  success  will  depend,  in part,  on its  ability  to retain the
services of its key personnel,  including  management and scientific  employees,
who are and will continue to be  instrumental  in the development and management
of the  Company's  business.  Although the Company has entered  into  employment
agreements  with its Chief  Executive  Officer and  certain of its other  senior
executives,  the  loss  of the  services  of one or more  of the  Company's  key
employees could have a material adverse effect on the Company.

Warranty Claims

The  Company  generally  provides a one-year  parts and labor  warranty  on each
IONSCAN(R),  although  from  time to time  the  Company  has  provided  extended
warranties.  Although  the  Company  has not  experienced  significant  warranty
claims,  there can be no  assurance  that such claims  will not  increase as the
Company's sales and product offerings increase.  Increased warranty claims could
have a material adverse effect on the Company's  business,  financial  condition
and results of operations.

Potential Product Liability Insurance Limits

The Company currently  maintains  product  liability  insurance in the amount of
$10.0 million per  occurrence.  The Company's  insurance  policy covers  certain
claims and the cost of legal fees involved in the defense of such claims,  which
are either  covered under the policy or alleged in such a manner so as to invoke
the  insurer's  duty to defend the Company.  The Company  believes  that,  as it
distributes  more products into the  marketplace  and expands its product lines,
its exposure to potential  product liability claims and litigation may increase.
There can be no assurance that the Company's  current level of insurance will be
sufficient  to protect the  business  and assets of the Company from all claims,
nor can any  assurance  be given that the Company  will be able to maintain  its
existing  coverage  or obtain  additional  coverage at  commercially  reasonable
rates.  Product  liability  losses in excess of insurance  coverage could have a
material  adverse  effect on the  Company's  business,  financial  condition and
results of operations.

Shares Eligible For Future Sale

Assuming that all of the Warrants covered hereby are exercised, 8,207,198 shares
of Common Stock will be  outstanding.  All of the shares  offered hereby will be
freely  tradable  unless  acquired by affiliates  of the Company.  The remaining
7,845,123  shares that will be outstanding  upon completion of this Offering are
freely  tradable.  An additional  1,183,836  shares of Common Stock are issuable
upon the exercise or  conversion  of  outstanding  stock  options,  warrants and
convertible securities outstanding as of April 30, 1998, 1,058,836 of which have
been  registered for resale by the holders  thereof and are,  therefore,  freely
tradable and the balance of which are subject to registration rights pursuant to
which the holders  thereof can cause the Company to effect the  registration  of
such shares for  resale.  In  connection  with a recent  public  offering by the
Company, certain officers and directors of the Company, who held an aggregate of
709,621 shares of Common Stock (including  534,550 shares issuable upon exercise
or conversion of outstanding options, warrants and convertible securities) as of
February  1, 1998,  agreed not to offer or sell,  directly  or  indirectly,  any
securities  of the  Company  in the  public  market for a period of 90 days from
March 30, 1998 (subject to certain  exceptions) without prior written consent of
the representatives of the underwriters of such offering.

The Company cannot predict the effect,  if any, that sales of additional  shares
of Common Stock or the  availability  of shares for future sale will have on the
market price of the Common Stock or the Warrants.  Sales in the public market of
substantial  amounts of Common Stock (including  shares issued upon the exercise
or conversion of outstanding options,  warrants and convertible securities),  or
the perception that 

<PAGE>

such sales might occur,  could adversely affect prevailing market prices for the
Common Stock or the Warrants. Such sales also may make it more difficult for the
Company to sell equity securities or equity related  securities in the future at
a time and price that the Company deems appropriate.

Effects of Warrants

Holders of the Warrants will have the  opportunity  to profit from a rise in the
market price of the Common Stock  without  assuming the risk of ownership of the
shares of Common  Stock  issuable  upon the  exercise of such  Warrants,  with a
resulting  dilution in the interests of the Company's  stockholders by reason of
exercise thereof at a time when the exercise price is less than the market price
for the Common  Stock.  Further,  the terms on which the  Company  could  obtain
additional  capital  during the life of the Warrants may be adversely  affected.
Holders of Warrants  may be expected to exercise  their  Warrants at a time when
the Company could, in all  likelihood,  obtain any needed capital by an offering
of Common Stock on terms more favorable than those provided by such Warrants.

Possible Redemption of Warrants

The Warrants  are  redeemable  by the Company for $0.25 per Warrant  (subject to
adjustment  under  certain  circumstances),  upon not less  than 30 days'  prior
written notice,  if the closing bid price of the Common Stock averages in excess
of 200% of the  exercise  price of the  Warrants  for a period of 30 days ending
within 15 days of the redemption  notice date.  Redemption of the Warrants could
force the holders thereof to exercise earlier than they would otherwise have, to
exercise  at a time when it may be  disadvantageous  for  holders to do so or to
sell at the  then-current  market price when  holders  might  otherwise  wish to
retain their Warrants for possible appreciation.  Alternatively, the holders may
accept the redemption price when it is likely to be substantially  less than the
then-current  market  value  thereof.  Any  holders  who do not  exercise  their
Warrants  prior to  redemption  will forfeit the right to purchase the shares of
Common Stock underlying such Warrants.

Current Prospectus to Exercise Warrants

The Warrants are not exercisable  unless,  at the time of exercise,  the Company
has a current  prospectus  covering  the shares of Common  Stock  issuable  upon
exercise of such Warrants. In addition, in the event that any holder of Warrants
attempts to exercise  such  Warrants at any time after nine months from the date
of this  Prospectus,  the  Company  may be  required  to  file a  post-effective
amendment and deliver a current prospectus before the Warrants can be exercised.
Although  the  Company  has  undertaken  to use its best  efforts to  maintain a
current  prospectus  covering the Common  Stock  issuable  upon  exercise of the
Warrants,  there is no  assurance  that the  Company  will be able to do so. The
value of the Warrants may be greatly  reduced if a current  prospectus  covering
the Common Stock issuable upon exercise of the Warrants is not kept effective.

Absence of Public Market for Warrants; Potential Volatility of Stock Price

While the Warrants  trade  sporadically  on the Nasdaq  National  Market System,
there can be no assurance  that an active trading market in the Warrants will be
developed or, if developed, be maintained.  As a result, holders of the Warrants
may have  difficulty  selling,  or  otherwise  disposing  of, the  Warrants.  In
addition,  prior to this Offering,  there have been significant  fluctuations in
the  trading  price of the Common  Stock.  No  assurance  can be given that such
volatility will not continue following the completion of this Offering.

Certain Charter Provisions

The Company's  Certificate of  Incorporation,  as amended (the  "Certificate  of
Incorporation"),  contains  provisions  which require the favorable  vote of the
holders of not less than 80.0% of the outstanding shares of Common Stock for the
approval of any merger,  consolidation or other combination with, or sale, lease

<PAGE>

or exchange of all or substantially all of the assets of the Company to, another
entity  holding  more than  10.0% of the  Company's  outstanding  voting  equity
securities or any affiliate of such entity.  These  provisions  could discourage
potential  acquisition  proposals,  delay or  prevent a change in control of the
Company and limit the price that  certain  investors  might be willing to pay in
the future for shares of the Common Stock.

The Board of  Directors of the Company is empowered to issue shares of preferred
stock without  stockholder action. The existence of this "blank check" preferred
stock could render more  difficult or discourage an attempt to obtain control of
the Company by means of a tender offer,  merger,  proxy contest or otherwise and
may  adversely  affect the  prevailing  market  price of the Common  Stock.  The
Company currently has no plans to issue additional shares of preferred stock. In
addition,  Section 203 of the Delaware General Corporation Law restricts certain
persons from engaging in business combinations with the Company.

                                   THE COMPANY

     The Company is the world's  leading  manufacturer  (based on units sold) of
high sensitivity  equipment used for detecting and identifying  trace amounts of
plastic and other explosives and illegal drugs. The Company designs and produces
products  that employ a  proprietary  application  of ion mobility  spectrometry
("IMS")  technology that can detect and identify  targeted  compounds in amounts
smaller than one-billionth of a gram in approximately six seconds. The Company's
objective is to leverage its position as the world's  leading  provider of trace
detection  systems in its core markets and to become a leading supplier of other
advanced  technology  security  solutions.  The Company  intends to achieve this
objective  by further  penetrating  its  existing  markets,  leveraging  its IMS
technology  for  new   applications,   pursuing   strategic   relationships  and
acquisitions and expanding its sales and marketing capabilities.

     The Company's  current  principal  product,  the IONSCAN(R),  is a portable
desktop system used in explosives detection and drug interdiction  applications.
As of December  31,  1997,  the Company had sold over 700 units  (including  335
during 1997) in 39 countries.

     The  markets  for  the  Company's  IONSCAN(R)  currently  include  aviation
security, other transport security, facilities protection,  forensics, military,
corrections,  customs and law enforcement.  The Company's  customers include the
Federal Aviation  Administration,  the U.S. Air Force, the U.S. Coast Guard, the
U.S. Drug Enforcement Agency and the Federal Bureau of Investigation, as well as
customs  agencies in France,  Canada,  Australia  and Japan and  various  prison
facilities in the U.S. and  elsewhere.  The IONSCAN(R) is also installed at over
40  airports  and  transportation  centers in  countries  throughout  the world,
including  Gatwick Airport and Heathrow  Airport in the United Kingdom,  John F.
Kennedy  International  Airport and Chicago O'Hare International  Airport in the
United States and Kuala Lumpur Airport in Malaysia,  as well as the  Eurotunnel.
The Company believes that its principal competitive advantages are the detection
capability,  reliability,  versatility,  cost  effectiveness,  ease  of use  and
portability of the IONSCAN(R). These advantages enable the IONSCAN(R) to be used
both in lieu of and in  conjunction  with  bulk  imaging  technologies,  such as
enhanced x-ray and computer aided tomography.

     The Company  believes  that many of the markets it serves are  experiencing
substantial growth, principally in reaction to heightened safety concerns caused
by the threat of terrorism and growing public awareness of drug-related criminal
activity.  The  Company  believes  that the  deployment  of  advanced  detection
equipment,  such as the IONSCAN(R),  will continue to increase as the acceptance
of using such equipment to combat these concerns increases. In January 1998, the
Company received a $5.4 million order from the FAA as part of the FAA's publicly
announced  intention to further  deploy  advanced  detection  technology  at the
nation's larger airports. In addition, during 1997, the Company sold a number of
IONSCAN(R)s  to the U.S.  Air Force for use in securing  certain  U.S. Air Force
bases in the U.S.  and abroad.  Also in 1997,  the Company  sold $2.5 million of
IONSCAN(R)s to a  correctional  agency to assist in stemming the flow of illegal
drugs to inmates.

     The  Company  markets  its  products  through a direct  sales  organization
comprised of 18 sales people  located at its  headquarters  in New Jersey and at
offices in Toronto,  London,  Paris and Kuala Lumpur.  In addition,  the Company
utilizes a network of 45 independent sales and service  representatives  located
in Europe, the Middle East, Africa, Asia, South America and Australia.

     The  Company  was  incorporated  under the laws of the State of Delaware on
September 7, 1967. The Company's  principal executive offices are located at 219
South Street,  Murray Hill, New Jersey 07974,  and its telephone number is (908)
665-8200.

                                 USE OF PROCEEDS

     If the  Warrants are  exercised in full at $9.847 per warrant,  the Company
would  receive  gross  proceeds  of  approximately  $3.6  million  (prior to the
deduction of fees and expenses incurred in connection with this Offering). Other
than the proceeds received by the Company from the exercise of the Warrants, the
Company will not receive any of the  proceeds  from the sale of the Common Stock
offered hereby.  The Company  estimates that its expenses in connection with the
Offering  will be  approximately  $15,000.  The  Company  intends to use the net
proceeds,  if any,  from the  exercise of the  Warrants  for  general  corporate
purposes.

                              PLAN OF DISTRIBUTION

     The Common Stock  offered  hereby may be offered and sold from time to time
by the Company  upon  exercise  of the  Warrants  by the  holders  thereof.  The
Warrants  may be  exercised  by the holders  thereof by  tendering  the exercise
price,  together with the warrant  certificate and exercise form, to the Company
before November 12, 1999, the expiration date of the Warrants.

     The distribution of the Common Stock issuable upon exercise of the Warrants
by the holders thereof, or by their respective pledgees,  donees, transferees or
other  successors in interest,  may be effected from time to time in one or more
transactions  on the  Nasdaq  National  Market  System,  in  special  offerings,
exchange  distributions  and/or  secondary  distributions  pursuant  to  and  in
accordance with the applicable  rules of the National  Association of Securities
Dealers,   Inc.  ("NASD"),   in  the  over-the-counter   market,  in  negotiated
transactions (including, without limitation, privately negotiated transactions),
through the writing of options on the Common  Stock,  or through the issuance of
other  securities  convertible  into shares of the Common  Stock  (whether  such
options or other  securities are listed on an options or securities  exchange or
otherwise),  or a combination of such methods of distribution,  at market prices
prevailing  at the time of sale,  at prices  related to such  prevailing  market
prices or at negotiated  prices. 

     Any or all of the Common Stock may be sold from time to time to  purchasers
directly by the holders thereof. In addition,  any such holders which are deemed
to be  "affiliates"  as defined under Rule 405 of the  Securities  Act, may make
sales of the Common Stock  pursuant to Rules 144, 144A or 904 of the  Securities
Act,  provided  that  the  requirements  of  such  rules,   including,   without
limitation, any applicable holding periods and manner of sale requirements,  are
met. Alternatively,  the holders of the Common Stock may from time to time offer
any or all of such  Common  Stock  through  underwriters,  dealers,  brokers  or
agents,  including  in  transactions  in which any such  underwriters,  dealers,
brokers or agents solicit  purchasers,  in block transactions or in transactions
in which any such underwriters, dealers, brokers, or agents will attempt to sell
such  shares of Common  Stock as an agent but may resell  such  shares of Common
Stock as a principal  pursuant to this Prospectus.  

     Any  underwriters,   dealers,   brokers  or  agents  participating  in  the
distribution of the Common Stock offered hereby may receive  compensation in the
form of  underwriting  discounts,  concessions,  commissions  or fees  from  the
original holders and/or  purchasers of the Common Stock for whom they may act as
agents  (which  compensation  may be in excess  of  customary  commissions).  In
addition,  the holders of such Common Stock and any such underwriters,  dealers,
brokers or agents that  participate in the  distribution  of Common Stock may be
deemed  to be  "underwriters"  within  the  meaning  of  Section  2(11)  of  the
Securities Act and any commissions received by them and any profit on the resale
of shares of the  Common  Stock may be deemed to be  underwriting  compensation.
Additionally,  the holders thereof may pledge shares of the Common Stock, and in
such  event  agents or dealers  may  acquire  the shares of the Common  Stock or
interests therein,  and may, from time to time, effect distribution of shares of
the  Common  Stock  or  interests  in such  capacity.

        SECURITIES AND EXCHANGE COMMISSION'S POSITION ON INDEMNIFICATION

     Article Tenth of the Company's  Certificate of Incorporation and Section 10
of the Company's  by-laws,  as amended,  provide that the Company shall,  to the
fullest extent  permitted by law,  indemnify  each person  (including the heirs,
executors,  administrators  and other personal  representatives  of such person)
against expenses (including attorneys' fees), judgments,  fines and amounts paid
in  settlement,  actually and  reasonably  incurred by such person in connection
with any  threatened,  pending or actual  suit,  action or  proceeding  (whether
civil,  criminal,  administrative  or  investigative  in nature or otherwise) in
which such person may be involved by reason of the fact that he or she is or was
a director  or officer of the Company or is serving  any other  incorporated  or
unincorporated  enterprise  in any of  such  capacities  at the  request  of the
Company. Such provisions may provide indemnification to the officers,  directors
or controlling  persons of the Company for liability  under the Securities  Act.

     Insofar as indemnification for liabilities arising under the Securities Act
may  be  permitted  to  directors,  officers  and  controlling  persons  of  the
registrant pursuant to the foregoing  provisions,  or otherwise,  the registrant
has been advised that in the opinion of the Securities  and Exchange  Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable.

                                  LEGAL MATTERS

     Certain  matters  with  respect to the  validity and legality of the Common
Stock offered hereby have been passed upon for the Company by Lowenstein Sandler
PC, Roseland, New Jersey.

for all securities registered pursuant to the Company's  Registration  Statement
on Form SB-2, as amended hereby, were previously paid by the Company).

                                                                         Expense

                                                                          -----

     All of the  above  amounts  (other  than  the  filing  fee  payable  to the
Securities  and  Exchange  Commission  and the listing fee payable to the Nasdaq
National  Market  System) are estimates  only. All of the above expenses will be
paid by the  Company.

Item  15.  Indemnification  of  Directors  and Officers 

     The  Certificate  of   Incorporation,   as  amended  (the  "Certificate  of
Incorporation"), and the Company's by-laws, as amended ("By-laws"), provide that
the Company shall, to the fullest extent permitted by law, indemnify each person
(including   the   heirs,   executors,   administrators   and   other   personal
representatives  of such person) against expenses  (including  attorneys' fees),
judgments,  fines  and  amounts  paid in  settlement,  actually  and  reasonably
incurred by such person in  connection  with any  threatened,  pending or actual
suit,  action  or  proceeding  (whether  civil,   criminal,   administrative  or
investigative  in nature or  otherwise)  in which such person may be involved by
reason of the fact that he or she is or was a director or officer of the Company
or is serving any other incorporated or unincorporated enterprise in any of such
capacities at the request of the Company.

     Section 145 of the General  Corporation  Law of the State of Delaware  (the
"GCL") permits a corporation,  under specified  circumstances,  to indemnify its
directors,  officers, employees or agents against expenses (including attorney's
fees),  judgments,  fines and amounts paid in settlement actually and reasonably
incurred by them in connection  with any action,  suit or proceeding  brought by
third parties by reason of the fact that they were or are  directors,  officers,
employees or agents of the corporation, if such directors,  officers,  employees
or agents acted in good faith and in a manner they reasonably  believed to be in
or not opposed to the best interests of the corporation and, with respect to any
criminal  action or  proceeding,  had no reason to  believe  their  conduct  was
unlawful.  In a  derivative  action,  i.e.,  one  by  or in  the  right  of  the
corporation,  indemnification  may  be  made  only  for  expenses  actually  and
reasonably  incurred by directors,  officers,  employees or agents in connection
with the defense or settlement of an action or suit,  and only with respect to a
matter as to which they  shall  have  acted in good  faith and in a manner  they
reasonably  believed  to be in or not  opposed  to  the  best  interests  of the
corporation,  except that no indemnification  shall be made if such person shall
have been judged  liable to the  corporation  unless and only to the extent that
the  court  in which  the  action  or suit  was  brought  shall  determine  upon
application  that the  defendant  directors,  officers,  employees or agents are
fairly and  reasonably  entitled to  indemnity  for such  expenses  despite such
adjudication of liability.

     The  Certificate of  Incorporation  also contains a provision  limiting the
personal liability of directors to the fullest extent permitted or authorized by
the GCL or other  applicable  law. Under the GCL, such provision would not limit
liability of a director for (i) breach of the director's  duty of loyalty,  (ii)
acts or

omissions  not in good  faith or  involving  intentional  misconduct  or knowing
violation of law,  (iii) payment of dividends or  repurchases  or redemptions of
stock other than from lawfully  available funds, or (iv) any  transactions  from
which the director derives an improper benefit.

Item 17.  Undertakings      

          The undersigned registrant hereby undertakes:

          (1) To file, during any period in which it offers or sells securities,
a post-effective amendment to this Registration Statement to:

               (i) Include any  prospectus  required by Section  10(a)(3) of the
Securities Act;

               (ii)  Reflect  in the  prospectus  any  facts  or  events  which,
individually or together,  represent a fundamental  change in the information in
the  registration  statement.  Notwithstanding  the  foregoing,  any increase or
decrease  in the volume of  securities  offered  (if the total  dollar  value of
securities offered would not exceed that which was registered) and any deviation
from  the  low or  high  end of the  estimated  maximum  offering  range  may be
reflected in the form of prospectus  filed with the Commission  pursuant to Rule
424(b) if, in the aggregate,  the changes in volume and price  represent no more
than a 20%  change  in the  maximum  aggregate  offering  price set forth in the
"Calculation of Registration Fee" table in the effective registration statement;
and

               (iii) Include any additional or changed material information with
respect to the plan of distribution.

               Provided,  however,  that  paragraphs  (1)(i) and  (1)(ii) do not
apply if the registration statement is on Form S-3, Form S-8 or Form F-3 and the
information  required  to be  included in a  post-effective  amendment  by those
paragraphs  is  contained  in periodic  reports  filed with or  furnished to the
Commission  by the  Company  pursuant  to  section  13 or  section  15(d) of the
Exchange Act that are incorporated by reference in the registration statement.

               (2) That, for the purpose of determining  any liability under the
Securities Act, each such  post-effective  amendment shall be deemed to be a new
registration  statement  relating to the  securities  offered  therein,  and the
offering of such  securities at that time shall be deemed to be the initial bona
fide  offering  thereof.

               (3) To  remove  from  registration  by means of a  post-effective
amendment  any of the  securities  being  registered  which remain unsold at the
termination of the offering.  

     Insofar as indemnification for liabilities arising under the Securities Act
may  be  permitted  to  directors,  officers  and  controlling  persons  of  the
registrant pursuant to the foregoing  provisions,  or otherwise,  the registrant
has been advised that in the opinion of the Securities  and Exchange  Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore,  unenforceable. In the event that a claim for indemnification
against such  liabilities  (other than the payment by the registrant of expenses
incurred or paid by a director,  officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director,  officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction the question whether such  indemnification  by it is against public
policy as  expressed  in the  Securities  Act and will be  governed by the final
adjudication of such issue.

certifies  that it has  reasonable  grounds to believe  that it meets all of the
requirements  for filing on Form S-3 and has duly caused this  amendment  to its
registration statement to be signed on its behalf by the undersigned,  thereunto
duly  authorized,  in the City of Murray  Hill,  State of New Jersey,  on May 5,
