                               NOTES TO FINANCIAL STATEMENTS
                                SEPTEMBER 30, 2003 AND 2002

NOTE A. SUMMARY OF ACCOUNTING POLICIES

     The  summary  of  the   Issuer's   significant   accounting   policies  are
incorporated by reference to the Company's annual report on Form 10KSB, at March
31, 2003.

     The  accompanying  unaudited  condensed  financial  statements  reflect all
adjustments,  which,  in the opinion of  management,  are  necessary  for a fair
presentation  of the results of operations,  financial  position and cash flows.
The results of the interim period are not necessarily  indicative of the results
for the full year.

NOTE B. STOCK BASED COMPENSATION

     The Company has stock based  compensation  plans,  which are described more
fully in Note 7 of the Company's annual report on Form 10KSB, at March 31, 2003.
The Company has adopted the disclosure-only provisions of Statement of Financial
Accounting  Standards  No.  123,  "Accounting  for  Stock-Based   Compensation."
Accordingly,  no  compensation  cost has been  recognized  for the stock  option
plans.  Had  compensation  cost  for  the  Company's  stock  option  plans  been
determined  based on the fair value at the grant date for awards in fiscal  2004
and 2003  consistent  with the  provisions  of SFAS No. 123, the  Company's  net
earnings and earnings per share for the fiscal second  quarter and  year-to-date
would have been reduced to the pro forma amount indicated below:

assumptions  used for  grants:  dividend  yield of 0%;  expected  volatility  of
approximately  14%  (2004)  and 20%  (2003);  discount  rate of 3.0%  (2004) and
(2003); and expected lives of 5 years.



ITEM 2. MANAGEMENT'S  DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

LIQUIDITY AND CAPITAL RESOURCES

     On September 30, 2003, the Company had cash and  short-term  investments of
$6,019,929.   In  addition,  the  Company  had  other  current  assets  totaling
$4,084,444 and total current assets of $10,104,373.  Current liabilities of Mesa
Laboratories, Inc. were $497,873, which resulted in a current ratio of 20.3:1.

     The Company has made net capital asset  purchases of $16,097 for the fiscal
year-to-date.

     The Company has  instituted a program to repurchase up to 300,000 shares 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.


RESULTS OF OPERATIONS

REVENUE

     Net sales for the six months ended September 30, 2003 increased  $44,703 or
1% to  $4,529,027  from the  $4,484,324  net sales level  achieved  for the same
six-month period last year. Net sales for the quarter  decreased  $155,583 or 6%
to $2,276,286  from the  $2,431,869 net sales level achieved in the same quarter
last year. Over the first six months of the fiscal year, revenues are up a small
amount compared to prior year. Datatrace sales for the six month period produced
a five percent gain while medical  instruments  decreased by approximately seven
percent.  Nusonics  products  have  increased  over thirty  percent for the same
period,  but this gain is on a much  smaller  base of  sales.  Net sales for the
quarter  were  down a small  amount  from the  prior  year  quarter,  but was up
slightly  from  last  quarter.  For  the  quarter,  medical  products  decreased
approximately  five  percent and Nusonics  products  almost  doubled.  Datatrace
products  decreased 17 percent from the prior year quarter,  which was helped by
initial  shipments of the Micropack  III product,  which  included  shipments of
backlogged product from the first quarter of that year.

COST OF GOODS SOLD

     Cost of goods  sold for the first six  months as a percent of net sales was
38%, which is unchanged from the same six-month  period last year. Cost of goods
sold for the current  quarter as a percent of net sales was 40%,  representing a
4% increase  compared to the 36% level in the same quarter last year.  While the
mix of products during the first six months of the fiscal year was fairly stable
compared  to prior  year  leading  to no change  in the cost of goods  sold as a
percent of sales,  the  quarter saw an increase in cost of goods sold due to the
lower Datatrace product sales described above.

SELLING, GENERAL AND ADMINISTRATIVE

     Selling,  general  and  administrative  expenses  for the first six  months
decreased 1% or $11,131 to  $1,063,940  from  $1,075,071 in the same period last
year. For the current  quarter,  selling,  general and  administrative  expenses
totaled  $479,127,  which was down 3% or $14,328 from  $493,455  expended in the
same  quarter  last year.  Marketing  expenses  increased  nine percent and five
percent  for the  quarter  and six  month  periods,  respectively  with  Medical
marketing  expenses  declining  two percent and five percent from the prior year
while Datatrace  marketing  expenses increased 14 percent for the quarter and 13
percent for the  six-month  period.  The  increase  in  marketing  expenses  for
Datatrace  products was due chiefly to higher  compensation  and  commissions to
outside sale  representatives.  Individual  marketing costs for medical products
trended down for the quarter and six month periods and were relatively unchanged
within the major expense categories.  Administration  costs decreased 17 percent
and nine percent for the quarter and six month periods due to the elimination of
consulting expenses during the first six months of the current fiscal year.

RESEARCH AND DEVELOPMENT

     Research  and  development  for the first six months  increased to $150,464
from $128,930,  which  represents a 17% increase from the same period last year.
Research  and  development  for the quarter was  $82,878,  which  represents  an
increase of $3,398 or 4% from the  $79,480  level  expensed in the same  quarter
last year.  Research and  development  costs  increased  for the quarter and six
month periods due to higher  compensation  and consulting  costs.  This trend is
expected  to  continue  throughout  the fiscal  year.  Development  of three new
versions of the Micropack III Logger that will measure other parameters  besides
temperature is proceeding well and is expected to see introduction  later in the
fiscal year. Development projects for the company's line of Dialysate Meters for
kidney dialysis have begun,  and we estimate that we will begin to introduce our
next generation medical instruments in the next fiscal year.

NET INCOME

     Net income for the six months  ended  September  30, 2003  decreased  3% to
$1,051,545 or $.33 per diluted  share from  $1,080,807 or $.32 per diluted share
last year.  Net income for the  quarter was  $528,418 or $.17 per diluted  share
compared to net income of $661,088 or $.20 per diluted share last year.  For the
quarter,  the decrease in net income  compared to last year was due chiefly to a
decreased in the sales of logging products, and the resulting change in mix. For
the  year-to-date,   income  was  down  slightly  due  to  higher  research  and
development  spending and a small  increase in income tax rate compared to prior
year.
