ITEM 1.  DESCRIPTION OF BUSINESS.

Introduction

	Mesa Laboratories, Inc. (hereinafter referred to as the "Company" or 
"Mesa") was incorporated as a Colorado corporation on March 26, 1982.  The 
Company designs, develops, acquires, manufactures and markets instruments and 
systems utilized in connection with industrial applications and hemodialysis 
therapy.  In August 1984, the Company acquired Western Laboratories Corp., a 
manufacturer and marketer of a line of instruments for use in calibrating 
hemodialysis proportioning equipment.  In June 1989, the Company acquired the 
DATATRACE? product line of Ball Corporation.  In February 1993, the Company 
acquired the assets of NUSONICS, Inc., a manufacturer of ultrasonic flow 
meters and analyzers.

	The Company presently markets the DATATRACE? and ELOGG? recording 
systems which are used in various industrial applications; NUSONICS? 
Concentration Analyzers, Pipeline Interface Detectors and Flow Meter products 
which are used in various industrial applications; and two product lines used 
in kidney dialysis [Western Meters and the ECHO Reprocessor].  The Company is 
also performing research and development to expand the application of its 
technology.

	All statements other than statements of historical fact included in this 
annual report regarding the Company's financial position and operating and 
strategic initiatives and addressing industry developments are forward-looking 
statements.  Where, in any forward-looking statement, the Company, or its 
management, expresses an expectation or belief as to future results, such 
expectation or belief is expressed in good faith and believed to have a 
reasonable basis, but there can be no assurance that the statement of 
expectation or belief will result or be achieved or accomplished.  Factors 
which could cause actual results to differ materially from those anticipated, 
include but are not limited to general economic, financial and business 
conditions; competition in the kidney dialysis market; competition in the data 
logging market; competition in the fluid measurement market; the business 
abilities and judgement of personnel; the impacts of unusual items resulting 
from ongoing evaluations of business strategies; and changes in business 
strategy.

	Mesa's executive offices are located at 12100 West Sixth Avenue, 
Lakewood, Colorado 80228, telephone (303) 987-8000.

Data Logging

	The world market for temperature sensors, indicators and recorders is 
currently estimated at over $2 billion and is projected to grow at an annual 
rate of 4-6% over the next several years.  The electronics-based thermal 
sensor market to which DATATRACE? products belong currently exceeds $100 
million and is expected to expand at a rate of between 9% and 11%.

	The temperature and humidity recording markets are highly segmented.  
DATATRACE? products have developed application niches within major industry 
segments such as food processing, medical sterilization, pharmaceutical 
processing, transportation, electronics, aerospace, storage facilities and 
textile manufacturing.  DATATRACE? products are used in any industry where 
temperature, pressure or humidity is critical to the manufacturing process, 
quality of the product or where product temperature, pressure or humidity 
profiles are required in a continuous or moving process environment.

DATATRACE? Micropack Tracers, FRB Tracers and Flatpack Tracers

	The Micropack Tracer utilizes the latest advances in microcircuitry, 
power supply and sensor technologies.  The instrument is computer based and 
can be programmed by the user to take and store up to 1,000 temperature, 
temperature and humidity or temperature and pressure readings.  A lithium 
battery is utilized so that the device is completely self-contained and 
requires no external wires or cables.  The devices operate at temperatures 
from - 40?F to 680?F and provide both high accuracy and reliability.  
Currently, the Micropack Tracers for temperature are sold with various probe 
configurations in three temperature ranges:  LoTemp?, which records 
temperatures from  -40?F to 185?F;  Standard Temp?, which records temperatures 
from 50?F to 302?F; and HiTemp?, which records  temperatures from 212?F to 
680?F.  The Flatpack Tracer provides the customer with a flat profile 
instrument in addition to the round Micropack Tracer.  The Flatpack Tracer is 
offered in the same temperature ranges and probe configurations as the 
Micropack Tracer.  Offering the same features but slightly larger than the 
Micropack Tracer, the FRB Tracer provides users with the ability to replace 
batteries at their facility, lowering operating cost and down time for factory 
replacement of the battery.  Utilizing the same electronics and FRB Tracer 
packaging, the Company introduced a humidity and temperature version of its 
FRB Tracer product in late March, 1997, and a pressure and temperature version 
of its FRB Tracer product in July 1997.

	The DATATRACE? Tracers can be placed completely inside a container or 
process to provide true time and temperature or time, temperature and 
humidity, or time, temperature and pressure profiles of manufacturing 
processes, transportation systems and storage facilities.  Optional probe 
configurations and attachments allow the Tracers to be adapted to a wide 
variety of applications.  By eliminating the need for wires or cable 
connections, the Tracer greatly reduces set up time while increasing 
measurement reliability.

DATATRACE? PC Interface

	The DATATRACE? product line also includes a PC Interface Module and 
system software for user programming of the Tracer instruments for graphics 
software and displaying and analyzing results.  Programming and retrieval of 
data from the Tracer is achieved by placing the instrument in the PC Interface 
Module which is linked to a personal computer.  The system's software is menu 
driven, allowing the operator to quickly and easily program start time and 
date, sample intervals and run ID.  Programming can be accomplished within 
fifteen seconds by the operator.  After a process run, data is retrieved by 
returning the Tracer to the PC Interface Module and following the menu 
instructions.

ELOGG? Dataloggers

	The Company distributes the ELOGG? Datalogger product line in North 
America.  The ELOGG? line is similar in concept to the DATATRACE? line, 
featuring different benefits to the end-user such as longer battery life, 
extended memory and humidity logging in certain models.  Unlike the DATATRACE? 
products, the ELOGG? is a larger device which is not as environmentally 
resistant and is ideally suited for long-term monitoring applications, such as 
transportation and warehousing.  The ELOGG? line also features a PC Interface 
Module and software for user programming.


Sonic Fluid Measurement

	The Company's sonic fluid measurement product line consists of two major 
segments: Sonic Flow Meters and Concentration Monitors.  While the total 
market for flow meters is very large, the NUSONICS? Sonic Flow Meters best 
serve applications where cleanliness, resistance to corrosives or portability 
are required.  Specific applications where the NUSONICS? products are 
particularly well suited include water treatment, chemical processing and 
heating, ventilation and air conditioning (HVAC) applications.

	The Concentration Monitor segment of the product line consists of 
Pipeline Interface Detectors and Concentration Analyzers.  The Pipeline 
Interface Detector serves a smaller market niche while the Concentration 
Analyzers serve a wider variety of industry application, such as chemical and 
food processing, pharmaceutical processing and polymerization processes.

NUSONICS? Sonic Flow Meters

	The Sonic Flow Meter line is a range of products which are suited to 
various measurement applications.  Introduced during fiscal 1995, the Model 
CM800 Sonic Flow Meter is the Company's main wetted transducer meter.  With 
transducers that are mounted through the pipe wall and in contact with the 
material flowing through the pipe, it is the most accurate type of ultrasonic 
flow meter.  The Model 90 Sonic Flow Meter features strap-on transducers and 
is sold in portable and fixed process versions.  This product offers 
flexibility and portability for measuring flow and is totally noninvasive, 
measuring flow rates through the pipe wall.  The Company offers flow 
measurement products directed toward the heating, ventilation and air 
conditioning (HVAC) market.  The Balance Master Meter is a hand-held portable 
meter which quickly plugs into specialized flow stations with window seal 
ports.  This meter allows the plant engineer to quickly read and adjust flow 
within a building.  The CM800 Flow Meter utilizes the same window seal flow 
stations as the Balance Master to provide continuous flow monitoring for use 
in energy management systems.  In addition, the Company markets doppler flow 
meters in both permanent and strap-on transducer models.  Unlike the transit-
time technology that the Company's other flow products utilize to measure 
clean fluids with dissolved solids, the doppler technology is utilized when 
the fluids to be measured contain either suspended solids or entrained gases.

NUSONICS? Sonic Concentration Analyzers

	Liquid composition can be determined by measuring sound velocity.  Since 
the sound velocity of any liquid is unique, the relationship between sound 
velocity, liquid composition and temperature is different for every liquid.  
Once the relationship is known, sound velocity can be used to monitor changes 
in liquid composition, often with much greater precision than can be realized 
with other measuring devices.

	Composition Analyzers are marketed to various industrial users and are 
currently used to monitor more than 250 different materials.  On a real time 
basis, the analyzer will monitor the composition of materials for process 
control of blending operations or for tracking the progress of polymerization 
processes.  This product line is currently led by the Model 86 Composition 
Monitor.  In addition, the Company also offers Model 87 (a laboratory model) 
and the Model 88 (which provides new signal processing technology).

	Based on the same technology as the Composition Analyzers, the Company 
also markets Pipeline Interface Detectors to the petroleum pipeline industry. 
 This instrument is used to monitor the interface of similar materials in a 
pipeline, such as different grades of unleaded fuel.  By detecting these 
interfaces, the pipeline operator can accurately perform switching operations 
within the pipeline system.

Kidney Hemodialysis Treatment

	Patients with kidney failure (known as end stage renal disease, or ESRD) 
require the removal of toxic waste products and excess water through 
artificial means.  This process needs to be performed three times per week and 
is most often accomplished through the use of hemodialysis.

	Hemodialysis requires the treatment to be conducted on a dialysis 
machine through the use of a disposable cartridge known as a dialyzer.  Blood 
is brought extracorporally to the dialysis machine for control and monitoring 
and passes through the dialyzer where waste products and excess water are 
removed.  This treatment generally lasts three to four hours and is conducted 
three times per week.  These hemodialysis procedures are performed in kidney 
dialysis centers, hospitals and in the home.  The bulk of the treatments are 
conducted in over 3,000 clinics and hospital centers.  Currently, there are 
over 250,000 patients in the U.S. undergoing dialysis therapy.

	In addition to the reimbursement policies of the United States 
Government and state agencies, the Company's revenues from its dialysis 
products can be expected to be dependent upon the policies of insurance 
companies and kidney foundations.

Western Meters

	Mesa's Western Meters are instruments that are used to test various 
parameters of the dialysis fluid (dialysate).  The meter line consists of five 
different meters.  Each measures some combination of temperature, pressure, pH 
and conductivity to ensure that the dialysate has the proper constituency to 
promote the transfer of waste products from the blood to the dialysate.  The 
meters are used to check the conductivity and other variables of the dialysate 
before the dialysis process begins.  The meters provide a digital readout that 
the patient, physician or technician uses to verify that the dialysis unit is 
working within prescribed limits.

	The Company's Western Meter product line consists of two different 
meters.  Model 90BC is used by dialysis centers and measures conductivity, 
temperature and pressure.  Model 90DX, the most advanced Western Meter, 
measures conductivity, temperature, pressure and pH.  Model 90DX is 
microprocessor-based and features improved accuracy and user convenience and 
field calibration capabilities.

The ECHO MM-1000 Dialyzer Reprocessor

	Dialyzer reuse is a procedure in which a patient's dialyzer is cleaned, 
performance tested and disinfected before it is reused by the same patient.  
The approximate cost of the dialyzer is $15-$55, and each patient requires 
approximately 156 dialyzers annually if no reuse is employed.  Although the 
Company has not conducted a scientific market survey, it estimates that more 
than 80% of the hemodialysis patients being treated in centers are involved 
with reuse programs.

	The ECHO MM-1000 Dialyzer Reprocessor is a fully automated dialyzer 
reuse machine for which the Company received permission to market from the FDA 
in June 1982.  It automatically cleans, rinses, tests and delivers 
disinfectants to dialyzers after dialysis therapy, thereby allowing the 
dialyzer cartridges to be reused rather than disposed of after each use.  It 
is designed to accommodate virtually all manual reprocessing procedures in use 
today and can be programmed to automate them without extensive modification or 
rework.  Manual procedures have been used to reprocess dialyzers effectively 
for over 30 years and are the basis of most automated systems in use today.  
Additionally, the system can be programmed to use prescribed chemicals.  The 
ECHO System is totally self-contained, aside from water and chemicals, and 
requires no user adjustments.

Manufacturing

	The Company assembles its manufactured products at its facility in 
Lakewood, Colorado.  The Company's manufacturing consists primarily of 
assembling and testing materials and component parts purchased from others.

	Most of the materials and components used in the Company's product lines 
are available from a number of different suppliers.  Mesa generally maintains 
multiple sources of supplies for most items but is dependent on a single 
source for certain items.  Mesa believes that alternative sources could be 
developed, if required, for present single supply sources.  Although the 
Company's dependence on these single supply sources may involve a degree of 
risk, to date, Mesa has been able to acquire sufficient stock to meet its 
production schedules.

Marketing and Distribution

	The Company's domestic sales of its dialysis products are generated by 
its in-house marketing staff while the Company maintains an organization of 
independent manufacturers' representatives to distribute its DATATRACE? and 
ELOGG? product lines.  For its NUSONICS? product lines, a separate 
organization of manufacturers' representatives is maintained while a 
distributor network is being used for the Company's HVAC product line.  
International sales are conducted through over 50 distributors.  During the 
fiscal year ended March 31, 1998, approximately 58% of sales have been 
domestic and 42% have been international to countries throughout Europe, 
Africa, Australia, Asia and South America, as well as Canada and Mexico.

	Sales promotions include attendance by Mesa representatives at 
conventions, the continuation of direct mail campaigns and trade journal 
advertising in industry related publications.

	Customers of Mesa's dialysis products primarily include dialysis centers 
and dialysis equipment manufacturers.  The primary emphasis of the Company's 
marketing effort is to offer quality products to the healthcare market which 
will aid in cost containment and improved patient well-being.

	DATATRACE? and ELOGG? customers include numerous industrial users who 
utilize the products within a variety of manufacturing, transportation and 
storage applications.  The emphasis of the Company's marketing effort is to 
offer a quality product that provides a unique and flexible solution to 
monitoring temperature or humidity without interfering with the processing, 
transportation or storage of the product.

	NUSONICS? customers include various industries such as water treatment, 
manufacturing, HVAC and petroleum product transportation.  The Company's 
marketing efforts are focused on offering flow measurement and concentration 
monitoring in difficult environments where noninvasive monitoring techniques 
are required.

	During the fiscal year ended March 31, 1998, no single customer 
accounted for 10% or more of the Company's revenues.  The Company does not 
believe that it is dependent upon a single customer or a few customers, whose 
loss would have a long term adverse effect upon the Company's business.

Competition

	Mesa competes with major medical and instrumentation companies as well 
as a number of smaller companies, many of which are well established, with 
substantially greater capital resources and larger research and development 
facilities.  Furthermore, many of these companies have an established product 
line and a significant operating history.  Accordingly, the Company may be at 
a competitive disadvantage due to such factors as its limited resources and 
limited marketing and distribution network.

	Companies with which Mesa's medical products compete include Minntech 
Corp. and Automata, Inc.  Companies with which Mesa's DATATRACE? and ELOGG? 
instrumentation products compete include  Testoterm, Inc. and Rustrak 
Instruments.  Companies with which Mesa's NUSONICS? products compete include 
Controlotron, Badger Meter and Panametrics.

	In the area of dialyzer reuse, management believes that the availability 
of an automated reprocessing system which consistently cleans, rinses and 
disinfects dialyzers, as well as tests them for physical performance and 
leaks, can dramatically alter the reuse patterns.  Mesa believes that it is 
the largest supplier of meters used to calibrate hemodialysis equipment, 
although it has not conducted independent market surveys.  The DATATRACE? and 
ELOGG? products offer unique solutions to monitoring temperature or humidity 
and temperature or pressure and temperature through a continuous process or 
long-term transportation and warehousing applications.  Although there are 
other solutions to temperature, humidity and pressure monitoring available, 
the DATATRACE? products offer a miniaturized, self-contained, environmentally 
resistant, wireless solution.  NUSONICS? products offer solutions to 
monitoring of clean fluids as well as highly corrosive materials, which are 
either noninvasive or do not disturb the flow of the product through the pipe. 
 NUSONICS? products also offer a unique solution to monitoring variations in a 
fluid's concentration as the fluid passes through a pipeline into or out of a 
process.

Government Regulation

	Medical devices marketed by Mesa are subject to the provisions of the 
Federal Food, Drug and Cosmetic Act, as amended by the Medical Device 
Amendments of 1976 (hereinafter referred to as the "Act").  A medical device 
which was not marketed prior to May 28, 1976, or is not substantially 
equivalent to a device marketed prior to that date, may not be marketed until 
certain data is filed with the FDA and the FDA has affirmatively determined 
that such data justifies marketing under conditions specified by the FDA.  A 
medical device is defined by the Act as an instrument which (1) is intended 
for use in the diagnosis or the treatment of disease, or is intended to affect 
the structure of any function of the human body; (2) does not achieve its 
intended purpose through chemical action; and (3) is not dependent upon being 
metabolized for the achievement of its principal intended purpose.  The Act 
requires any company proposing to market a medical device to notify the FDA of 
its intention at least ninety days before doing so, and in such notification 
must advise the FDA as to whether the device is substantially equivalent to a 
device marketed prior to May 28, 1976.  As of the date hereof, the Company has 
received permission from the FDA to market all of its medical products.

	Mesa's medical products are subject to FDA regulations and inspections, 
which may be time-consuming and costly.  This includes on-going compliance 
with the FDA's current Good Manufacturing Practices regulations which require, 
among other things, the systematic control of manufacture, packaging and 
storage of products intended for human use.  Failure to comply with these 
practices renders the product adulterated and could subject the Company to an 
interruption of manufacture and sale of its medical products and possible 
regulatory action by the FDA.

	The manufacture and sale of medical devices is also regulated by some 
states.  Although there is substantial overlap between state regulations and 
the regulations of the FDA, some state laws may apply.  Mesa, however, does 
not anticipate that complying with state regulations will create any 
significant problems.  Foreign countries also have laws regulating medical 
devices sold in those countries.

Employees

	At March 31, 1998, the Company had a total of 42 employees, of which 40 
were full-time employees.  Currently, eight persons are employed for 
marketing, three for research and development, 25 for manufacturing and 
quality assurance and six for administration.

Additional Information

	For the fiscal years ended March 31, 1998 and 1997, Mesa spent 
approximately $264,151 and $253,661, respectively, on Company-sponsored 
research and development activities.

	Compliance with federal, state and local provisions which have been 
enacted regarding the discharge of materials into the environment or otherwise 
relating to the protection of the environment has not had, and is not expected 
to have, any adverse effect upon capital expenditures, earnings or the 
competitive position of the Company.  Mesa is not presently a party to any 
litigation or administrative proceedings with respect to its compliance with 
such environmental standards.  In addition, the Company does not anticipate 
being required to expend any capital funds in the near future for 
environmental protection in connection with its operations.

	The Company has been issued patents for its DATATRACE? temperature 
recording devices and its NUSONICS? sonic flow measurement and sonic 
concentration monitoring products.  Failure to obtain patent protection on the 
Company's remaining products may have a substantially adverse effect upon the 
Company since there can be no assurance that other companies will not develop 
functionally similar products, placing the Company at a competitive 
disadvantage.  Further, there can be no assurance that patent protection will 
afford protection against competitors with similar inventions, nor can there 
be any assurance that the patents will not be infringed or designed around by 
others.  Moreover, it may be costly to pursue and to prosecute patent 
infringement actions against others, and such actions could interfere with the 
business of the Company.

ITEM 2.  DESCRIPTION OF PROPERTY.

	Mesa owns its 39,616 square foot facility at 12100 W. 6th Avenue, 
Lakewood, Colorado 80228.  All manufacturing, warehouse, marketing, research 
and administrative functions are based at this location.  The facility is 
approximately 60% utilized and should provide adequate capacity for continued 
expansion.

	The Company does not invest in, and has not adopted any policy with 
respect to investments in, real estate or interests in real estate, real 
estate mortgages or securities of or interests in persons primarily engaged in 
real estate activities.  It is not the Company's policy to acquire assets 
primarily for possible capital gain or primarily for income.

ITEM 3.  LEGAL PROCEEDINGS.

	No material legal proceedings to which the Company is a party or to 
which any of its property is the subject are pending, and no such proceedings 
are known by the Company to be contemplated.  The Company is not presently a 
party to any litigation or administrative proceedings with respect to its 
compliance with federal, state and local provisions which have been enacted 
regarding the discharge of materials into the environment or otherwise 
relating to the protection of the environment and no such proceedings are 
known by the Company to be contemplated.  No legal actions are contemplated 
nor judgments entered against any officer or director of the Company 
concerning any matter involving the business of the Company.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

	No matter was submitted during the fourth quarter of the fiscal year 
covered by this report to a vote of security holders through the solicitation 
of proxies or otherwise.

ITEM 6.  MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION.

Results of Operations

Net Sales

	Net sales for fiscal 1998 increased 2% from fiscal 1997.  In real 
dollars, net sales of $7,921,949 in fiscal 1998 increased $147,899 from 
$7,774,050 in 1997.  Net sales increase in fiscal 1998 was due to strong 
increases in sales of Medical and Datatrace products which were mostly off-set 
by a decrease in Nusonics product sales.  Net sales declined in fiscal 1997 
due largely to a decrease in international sales resulting from declines in 
European and South American sales.  During fiscal 1997, Medical and Datatrace 
sales both increased while Nusonics product sales declined from the prior 
fiscal year.

	During fiscal 1998, sales of Nusonics products declined by 28%.  In 
order to correct this decline, the Company reorganized its sales organization 
in order to improve its ability to meet the technical demands of its 
concentration monitor products.  In addition, the Company is having an in-
depth study of its position within the ultrasonic segment of the flow meter 
market conducted.  For the past year, the Company has focused its research and 
development efforts on a new electronic design to be used as the technical 
foundation of its next generation of flow meters and concentration analyzers. 
 Within the flow meter segment of the product line, Mesa must focus on 
developing those sets of features and price performance attributes that will 
best meet the market's evolving needs.

Cost of Sales

	Cost of sales as a percent of net sales in fiscal 1998 declined 4.2% 
from fiscal 1997 to 33.5%.  During fiscal 1998, Medical costs decreased 2.7%, 
Datatrace costs decreased 4.4% and Nusonics costs decreased 1.5% as a percent 
of sales.  For fiscal 1997, the cost of Nusonics products increased 6.5% and 
Medical products increased 2.5%, respectively, while Datatrace products 
decreased 6.4% as a percent of sales.  The decrease in Datatrace cost of sales 
in fiscal 1998 was due to utilization of a new electronic circuit, which 
greatly reduced the materials cost of the product.  The decrease in Nusonics 
cost of sales in fiscal 1998 was due to reductions in material and labor 
costs, while the decrease in Medical was attributable chiefly to a decline in 
material costs.  In fiscal 1997, the decrease in Datatrace was due to the new 
electronic circuit that reduced the materials cost of the product.  The 
increase in Nusonics cost of sales was due to an increase in the ratio of 
domestic sales, while the increase in Medical was due to a higher ratio of 
distributor sales.

Selling, General and Administrative

	Selling expenses decreased 5% from fiscal 1997 to fiscal 1998.  In real 
dollars, selling expenses decreased $67,535 to $1,301,762 in fiscal 1998 from 
$1,369,297 in fiscal 1997.  The decrease in selling expenses in fiscal 1998 
was due to a sharp decline in Nusonics selling expense which was partially 
off-set by increases in Medical and Datatrace selling expenses.  Selling 
expenses also decreased from fiscal 1996 to fiscal 1997.  This decrease was 
due to reductions in outside sales commissions for Nusonics international 
sales.

	General and administrative expenses were $801,603 in fiscal 1998 and 
$715,215 in fiscal 1997, which represents a $86,388 or 12% increase from 
fiscal 1997 to fiscal 1998.  The increase in general and administrative costs 
during fiscal 1998 was due to increased compensation and business development 
costs.

Research and Development

	Company sponsored research and development costs were $264,151 in fiscal 
1998 and $253,661 in fiscal 1997, which represents a 4% increase from year to 
year.  Research and development costs increased in fiscal 1998 due chiefly to 
increased compensation costs.  Costs during fiscal 1997 declined due to 
reductions in compensation costs during the second half of the fiscal year 
following the retirement of the Company's Director of Research and 
Development.

Net Income

	Net income increased 19% to $2,052,314 or $.47 per share on a diluted 
basis in fiscal 1998 from $1,719,805 or $.39 per share on a diluted basis in 
fiscal 1997.  During fiscal 1998, net income increased due to increased sales 
of Medical and Datatrace products and reductions of cost of goods sold for all 
of the Company's product lines.  Net income increased during fiscal 1997 due 
to a decrease in cost of goods sold as a percent of sales combined with 
decreases throughout the operating expense categories.

Liquidity and Capital Resources

	On March 31, 1998, the Company had cash and short term investments of 
$5,407,167.  In addition, the Company had other current assets totaling 
$3,811,207 and total current assets of $9,218,374.  Current liabilities of 
Mesa Laboratories, Inc. were $544,221 which resulted in a current ratio of 
17:1.  For comparison purposes at March 31, 1997, Mesa Laboratories, Inc. had 
cash and short term investments of $3,867,549, other current assets of 
$3,746,772, total current assets of $7,614,321, current liabilities of 
$575,473 and a current ratio of 13:1.

	Mesa Laboratories, Inc. has made net capital purchases of $193,980 
during the past fiscal year.

	The Company has instituted a program to repurchase up to 10% of its 
outstanding common stock.  Under the plan, the shares may be purchased from 
time to time in the open market at prevailing prices or in negotiated 
transactions off the market.  Shares purchased will be canceled and 
repurchases will be made with existing cash reserves.

	The Company is currently working to resolve the potential impact of the 
year 2000 on the processing of date-sensitive information by the Company's 
computerized information systems.  The year 2000 problem is the result of the 
computer programs being written using two digits (rather than four) to define 
the applicable year.  Any of the Company's programs that have time-sensitive 
software may recognize a date using "00" as the year 1900 rather than the year 
2000, which could result in miscalculations or system failures.  Based on 
preliminary information, costs of addressing potential problems are not 
currently expected to have a material adverse impact on the Company's 
financial position, results of operations or cash flows in future periods.  
However, if the Company, its customers or vendors are unable to resolve such 
processing issues in a timely manner, it could result in a material financial 
risk.  Accordingly, the Company plans to devote the necessary resources to 
resolve all significant year 2000 issues in a timely manner.

	NOTES TO FINANCIAL STATEMENTS

 1.	Summary of Significant Accounting Policies:

	General - Mesa Laboratories, Inc. was incorporated under the laws of the State
 of Colorado on March 26, 1982, for the purpose of designing, manufacturing
 and marketing electronic instruments and supplies.

	Concentration of Credit Risk - Financial instruments which potentially
 subject the Company to concentrations of credit risk consist of money market
 funds and accounts receivable.  The Company invests primarily all of its
 excess cash in money market funds administered by reputable financial
 institutions, debt instruments of the U.S. government and its agencies and
 grants credit to its customers who are located throughout the United States
 and several 
foreign countries.  To reduce credit risk, the Company periodically evaluates
 the money market fund administrators and performs credit analysis of
 customers and monitors their financial condition.  Additionally, the Company
 maintains cash balances in bank deposit accounts which, at times, may exceed
 federally insured limits.  The Company has not experienced any losses in
 such accounts.

	Cash Equivalents - Cash equivalents include all highly liquid investments
 with an original maturity of three months or less.

	Marketable Securities - The Company has investments in debt securities
 guaranteed by the U.S. Government which are carried at cost and approximate
 fair market value.  Management's intent is to hold these securities until
 maturity which is less than one year.

	Inventories - Inventories are stated at the lower of cost or market, using
 the first-in, first-out method (FIFO) to determine cost (see Note 2).

	Property, Plant and Equipment - Property, plant and equipment is stated at
 acquisition cost.  Depreciation and amortization is provided using the
 straight-line method over the estimated useful lives of three to thirty-nine
 years (Note 3).

	Intangible Assets - Intangible assets are comprised of patents, trademarks
 and covenants not to compete, which were acquired in conjunction with the
 NUSONICS, Inc. and DATATRACE asset purchases.  These costs are being
 amortized on the straight-line basis over contractual and estimated useful
 lives ranging from three to forty years.

	Revenue Recognition - The Company recognizes revenues at the time products
 are shipped.

	Research & Development Costs - Costs related to research and development
 efforts on existing or potential products are expensed as incurred.

	Accrued Warranty Expense - The Company provides limited product warranty on
 its products and, accordingly, accrues an estimate of the related warranty
 expense at the time of sale.

	MESA LABORATORIES, INC.
	NOTES TO FINANCIAL STATEMENTS
	(CONTINUED)

	Earnings Per Share - Basic earnings per share is calculated using the
 average number of common shares outstanding.  Diluted earnings per share is
 computed on the basis of the average number of common shares outstanding
 plus the effect of outstanding stock options using the treasury stock
 method, which totalled 95,555 and 145,928 additional shares in 1998 and
 1997, respectively.

	Valuation of Long-Lived Assets - The Company assesses valuation of
 long-lived assets in accordance with Statement of Financial Accounting
 Standards (SFAS) No. 121, Accounting for the Impairment of Long-Lived Assets
 and for Long-Lived Assets to be disposed of.  The Company periodically
 evaluates the carrying value of long-lived assets to be held and used,
 including goodwill and other intangible assets, when events and
 circumstances warrant such a review.  The carrying value of a long-lived
 asset is considered impaired when the anticipated undiscounted cash flow
 from such asset is
 separately identifiable and is lessthan its carrying value.  In that event,
 a loss is recognized based on the amount by which the carrying value exceeds
 the fair market value of the long-lived asset.  Fair market value is
 determined primarily using the anticipated cash flows discounted at a rate
 commensurate with the risk involved.

	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 and 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.

	Advertising Costs - Advertising costs are expensed as incurred.  Advertising
 costs for the years ended March 31, 1998 and 1997 were $140,469 and
 $128,978, respectively.

	Income Taxes - The Company recognizes deferred tax liabilities and assets
 for the expected future tax consequences of events that have been included
 in the financial statements or tax returns.  Under this method, deferred
 tax liabilities and assets are determined based on the difference between
 the financial statements and tax basis of assets and liabilities using the
 enacted tax rates in effect for the year in which the differences are
 expected to reverse.  The measurement of deferred tax assets is reduce
amount of any tax benefits that, based on available evidence, are not
 expected to be realized. 

	Fair Value of Financial Instruments - The carrying amount of financial
 instruments including cash and cash equivalents, accounts receivable,
 accounts payable and accrued expenses approximated fair value as of
 March 31, 1998 because of the relatively short maturity of these
 instruments.

	Recently Issued Accounting Pronouncements - In 1997, the FASB issued
 Statement of Financial Accounting Standards No. 130, "Reporting
 Comprehensive Income" (SFAS 130), which establishes standards for reporting
 and display of comprehensive income, its components and accumulated
 balances.  Comprehensive income is defined to include all changes in equity
 except those resulting from investments by owners and distributions to
 owners.  Among other disclosures, SFAS 130 requires that all items that are
 required to be recognized under current accounting standards as components
 of comprehensive income, be
 reported in a financial statement that is displayed with the same prominence
 as other financial statements.  Currently the Company's only component,
 which would comprise comprehensive income, is its results of operations.

	Also, in 1997, the FASB issued Statement of Financial Accounting Standards
 No. 131, "Disclosures about Segments of an Enterprise and Related
 Information" (SFAS 131), which supersedes Statement of Financial Accounting
 Standards No. 14, "Financial Reporting for Segments of a Business
 Enterprise."  SFAS 131 establishes standards for the way that public
 companies report information about operating segments in annual financial
 statements and 
requires reporting of selected information about operating segments in
 interim financial statements issued to the public.  It also establishes
 standards for disclosure regarding products and services, geographic areas
 and major customers.  SFAS 131 defines operating segments as components of
 a company about which separate financial information is available that is
 evaluated regularly by the chief operating decision maker in deciding how
 to allocate resources and in assessing performance.  Management believes
 that SFAS 131 will not have a significant impact on the Company's disclosure
 of segment information in the future.

	SFAS 130 and 131 are effective for financial statements for periods
 beginning after December 15, 1997, and requires comparative information for
 earlier period to be restated.

 5.	Commitments:

	The Company has announced a plan to repurchase up to 10% of its outstanding
 common stock.  Under the plan, shares may be purchased from time to time in
 the open market at prevailing prices or in negotiated transactions off the
 market.  Shares purchased will be canceled and repurchase of shares will be
 funded through existing cash reserves.

 6.	Stockholders' Equity:

	The State of Colorado has eliminated the ability of Colorado corporations
 to retain treasury stock.  As a result, the Company reduced common stock to
 its average share value and further reduced retained earnings for the
 remainder of the cost of treasury stock acquired in each fiscal year.

	The Company has adopted two incentive stock option plans for the benefit of
 the Company's key employees, excluding its outside directors.  Under the
 terms of the plan, options are granted at an amount not less than 100% of
 the bid price of the underlying shares at the date of grant.  The options
 are exercisable for a term of five years and, during such term, may be
 exercised as follows:  25% after each year, and 100% anytime after the
 fourth year until the end of the fifth year.

	The Company has approved a nonqualified performance stock option plan for
 the benefit of the directors of the Company.  The Plan provides that each
 director of the Company serving as a director as of the first day after the
 end of the Company's fiscal year shall be granted the option to purchase
 5,000 shares of Common Stock, provided that the Company has achieved a net
 after-tax profit for the immediately prior fiscal year then ended.  Under
 the terms of 
the plan the options are 100% exercisable anytime after the first year until
 the end of the fifth year.  The purchase price of the Common Stock will be
 equal to 100% of the closing bid price of the Common Stock on the
 over-the-counter market on the date of grant.

	On October 3, 1996, the Company adopted a new nonqualified performance stock
 option plan for the benefit of the Company's outside Directors.  The plan
 provides that the outside Directors will receive grants to be determined
 and approved by the Company's inside Directors and not to exceed 20,000
 options per year per director.  Under the terms of the plan, the options
 are exercisable for a term of ten years and, during such term are
 exercisable as follows:  25% after each year, and 100% anytime after the
 fourth year until the end of the tenth year.  The purchase price of the
 common stock will be equal to 100% of the closing bid price of the common
 stock on the over-the-counter market on the date of grant.

 Compensation."  Accordingly, no compensation cost has been recognized for
 the stock option plans.  Had compensation cost for the Corporation's stock
 option plans been determined based on the fair value at the grant date for
 awards in 1998 and 1997 consistent with the provisions of SFAS No. 123, the

Compensation of Directors

	The Company has adopted a nonqualified performance stock option plan, 
approved by the shareholders of the Company in October 1991, for the benefit 
of the directors of the Company.  The plan provides that each director of the 
Company serving as a director as of the first day after the end of the 
Company's fiscal year shall be granted the option to purchase 5,000 shares of 
Common Stock, provided that the Company has achieved a net after-tax profit 
for the immediately prior fiscal year then ended.  The purchase price of the 
Common Stock will be equal to the fair market value of the Common Stock on the 
date of grant.  The date of grant is the first business day in the month 
following the end of the Company's most recently completed fiscal year.  The 
fair market value is an amount equal to 100% of the closing bid price of the 
Common Stock on the over-the-counter market on the date of grant.

	The options are granted for a term of up to five years and may be 
exercised at any time after one year from the date of grant until the end of 
the fifth year from the date of grant.  Any optionee may pay the exercise 
price by delivering shares of Common Stock with a value equal to the exercise 
price.  The Company has reserved 150,000 shares of its authorized but unissued 
Common Stock for possible issuance pursuant to the plan.





	On October 3, 1996, the Company adopted a new nonqualified performance 
stock option plan for the benefit of the Company's outside Directors.  The 
plan provides that the outside Directors will receive grants to be determined 
and approved by the Company's inside directors and not to exceed 20,000 
options per year per director.  Under the terms of the plan, the options are 
exercisable for a term of ten years, and during such term are exercisable as 
follows:  25% after each year, and 100% anytime after the fourth year until 
the end of the tenth year.  The purchase price of the common stock will be 
equal to 100% of the closing bid price of the common stock on the over-the-
counter market on the date of grant.

	On April 1, 1997, the Company's three outside directors were granted 
options to purchase 4,000 shares of Common Stock at $4.88 per share.  The 
Company's two inside directors each were granted options to purchase 4,000 
shares of Common Stock at a price of $4.88 per share for Mr. Duke and at a 
price of $5.36 per share for Mr. Schmieder.

	Currently, all outside directors received cash compensation of $500 for 
each Board of Directors meeting attended in person.

Incentive Stock Option Plans

	The Company has adopted three incentive stock option plans, approved by 
the shareholders of the Company in September 1984, October 1989 and November 
1993, respectively, for the benefit of the Company's employees.  The plans are 
administered by the non-participating members of the Board of Directors, who 
select the optionees and determine the terms and conditions of the stock 
option grant.  The exercise price for options granted under the plans cannot 
be less than the fair market value of the stock at the date of grant or 110% 
of such fair market value with respect to options granted to any optionee who 
holds more than 10% of the Company's Common Stock.  Options are not 
exercisable until one year after the date of grant and expire five years after 
the date of grant.  All outstanding options are subject to vesting provisions 
whereby they become exercisable over a four-year period.  The plans authorize 
options to purchase up to 200,000, 300,000 and 300,000 shares of Common Stock, 
respectively.

	As of March 31, 1998, options to purchase a total of 285,321 shares were 
outstanding, at exercise prices ranging from $2.19 to $7.70 per share.  
Further, as of March 31, 1998, options to purchase an aggregate of 109,604 
shares remained available for grant under the latter two plans.  The plan 
adopted in September 1984 was terminated effective June 1, 1993.  Options were 
granted during the fiscal year ended March 31, 1998, pursuant to the Company's 
incentive stock option plans, to each of the Company's executive officers.  
Options to purchase 5,000 shares and 4,000 shares at $4.88 per share were 
granted to Mr. Steven W. Peterson, Vice President-Finance and Mr. Paul Duke, 
Vice President, respectively.  Mr. Luke R. Schmieder, President, was granted 
options to purchase 4,000 shares at $5.36 per share.

Retirement Plan

	No retirement, pension or profit sharing program has been adopted by the 
Company.  The Company may offer stock bonuses, profit sharing or pension plans 
to key employees or executive officers of the Company in such amounts and upon 
such conditions as the Board of Directors may in its sole discretion 
determine.

ITEM 11.  SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT.

	The following table sets forth the number of shares of the Company's 
Common Stock owned beneficially as of March 31, 1998, by each person known by 
the Company to have owned beneficially more than five percent of such shares 
then outstanding, by each officer and director of the Company and by all of 
the Company's officers and directors as a group.  This information gives

Securities Exchange Act of 1934, as amended.  As far as is known to management
