                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)

Note 1 - Consolidated Financial Statements

The consolidated balance sheet as of March 31, 2003, the consolidated statements
of income for the three-month periods ended March 31, 2003 and 2002, and the
consolidated statements of cash flows for the three-month periods ended March
31, 2003 and 2002 have been prepared by us, without audit. However, all
adjustments (consisting solely of normal recurring adjustments) which are, in
the opinion of management, necessary to present fairly the financial position,
results of operations and cash flows at March 31, 2003, and for all periods
presented, have been made. The results of operations for the period ended March
31, 2003 are not necessarily indicative of operating results for the full year.

Certain information and footnote disclosures normally included in financial
statements prepared in accordance with accounting principles generally accepted
in the United States of America have been condensed or omitted. It is suggested
that these consolidated financial statements be read in conjunction with the
financial statements and notes included in our December 31, 2002 annual report
to shareholders.

Stock-Based Compensation

We use the intrinsic-value method for employee stock-based compensation pursuant
to Accounting Principles Board Opinion No. 25 (Opinion 25), ACCOUNTING FOR STOCK
ISSUED TO EMPLOYEES. Under the guidelines of Opinion 25, compensation cost for
stock-based employee compensation plans is recognized based on the difference,
if any, between the quoted market price of the stock on the date of grant and
the amount an employee must pay to acquire the stock.

We have adopted the disclosure-only provisions for employee stock-based
compensation and the fair-value method for nonemployee stock-based compensation
of Statement of Financial Accounting Standard (SFAS) No. 123, ACCOUNTING FOR
STOCK-BASED COMPENSATION. No stock options were granted during the three-month
periods ended March 31, 2003 and 2002.

Had we recorded compensation cost based on the estimated fair value on the date
of grant, as defined by SFAS No. 123, our net income and net income per common
share would have been reduced to the pro forma amounts indicated below:

Note 3 - Net Income Per Common Share

Basic net income per common share is computed by dividing net income by the
weighted average number of shares of common stock outstanding during the period.
Diluted net income per common share is computed using the treasury stock method
to compute the weighted average common stock outstanding assuming the conversion
of potential dilutive common shares.

The following table presents a reconciliation of the denominators used in the
computation of net income per common share - basic and net income per common
share - diluted for the three- month periods ended March 31, 2003, and 2002:

Note 5 - Marketable Securities

Available-for-sale securities are recorded at fair value. Unrealized holding
gains and losses on available-for-sale securities are excluded from income and
are reported as a separate component of stockholders' equity until realized. At
March 31, 2003, and March 31, 2002, this resulted in a net unrealized gain of
$1,669 and $5,358, respectively, within stockholders' equity.

alteration, damage resulting from accident, or failure to follow manufacturer's
directions, are excluded from warranty coverage.

Warranty expense is accrued at the time of sales based on historical claims
experience. Special warranty reserves are also accrued for special rework
campaigns for known major product modifications. We also offer service contracts
for select products when the factory warranty period expires.

Summary

Sales increased 4 percent for the quarter ended March 31, 2003, compared to the
same period in 2002, and net income increased 1 percent. Both basic and diluted
earnings per share were 11 cents for both periods. International sales were 47
percent of sales in the three months ended March 31, 2003. We use a network of
independent representatives to market and service our products in foreign
countries, and expect that international sales will continue to account for a
significant portion of our revenues for the foreseeable future. We have four
operating locations, all of which are located in the United States.

Results of Operations

Sales for the quarter ended March 31, 2003, were $5,029,150, up 4 percent from
first quarter 2002 sales of $4,828,678. The increase in 2003 sales was primarily
the result of increases in the foreign sales volume of our permeation products
and domestic sales volume of our weighing products, offset somewhat by decreases
in the sales volume of our gas analyzer, sample preparation and gas
chromatography analyzer products. The impact of price increases was not
significant.

Total domestic sales for the quarter ended March 31, 2003, decreased 17 percent
from the first quarter of 2002 to $2,645,077, and total foreign sales increased
44 percent to $2,384,073. Domestic sales were 53 percent of total first quarter
2003 sales, compared to $3,172,697, or 66 percent, of first quarter 2002 sales.
Foreign sales were 47 percent of total first quarter 2003 sales, compared to
$1,655,981, or 34 percent, of first quarter 2002 sales. This increase was due
primarily to an increase in sales to customers in Japan.

We derive our revenue from product sales and consulting services, consisting of
standard laboratory testing services and consulting and analytical services
performed for various customers. In the first quarter of 2003, product sales
were $4,591,863 and consulting services were $437,287, or 91 and 9 percent,
respectively, of our total first quarter 2003 sales. This

                                       -8-
<PAGE>

compares to product sales of $4,387,612 and consulting services of $441,066 in
the first quarter of 2002, also 91 and 9 percent of total sales, respectively.

The cost of sales for product sales was 45 percent for the first quarters of
both 2003 and 2002. The cost of sales for consulting services sales was 49
percent and 61 percent for the first quarters of 2003 and 2002 respectively. The
decrease in the cost of consulting services sales between 2002 and 2003, both in
total dollars and as a percent of sales, was primarily the result of tighter
cost controls including lower headcount in 2003, particularly in the consulting
and analytical services area.

Selling, general and administrative expenses were 30 percent of total sales for
both the three-month periods ended March 31, 2003 and 2002. The $40,682 total
dollar increase for the three months ended March 31, 2003 is due primarily to an
increase in general and administrative expenses, including increases in
insurance costs and professional expenses, in 2003 versus 2002.

Research and development (R&D) expenses increased $47,162 in the first quarter
of 2003 compared to the first quarter of 2002. As a percent of sales, R&D
expenditures were 7 percent of sales for the quarter ended March 31, 2003, and 6
percent of sales for the quarter ended March 31, 2002. The increase is primarily
due to R&D expenses associated with the development of new permeation products.
Continued R&D expenditures are necessary as we develop new products to expand in
our niche markets and into new markets. For the foreseeable future, we expect to
spend on an annual basis approximately 6 to 8 percent of sales on R&D.

Investment income decreased $27,728 in the first quarter of 2003 as compared to
the first quarter of 2002. The decrease is the result of lower average
investment yields, offset somewhat by higher average investment balances in 2003
versus 2002.

Our provision for income taxes was 35 percent of income before income taxes for
the three- month period ending March 31, 2003 compared to 32.5 percent for the
same period in 2002. The increase in the rate is due in part to lower benefits
from export tax incentives and lower tax-exempt interest income. We review the
tax rate quarterly and may make adjustments to reflect changing estimates. Based
on current operating conditions and income tax laws, we expect the effective tax
rate for all of 2003 to be in the range of 34 to 36 percent.

Net income was $606,677 for the first quarter of 2003, compared to $597,836 for
the first quarter of 2002. Diluted net income per share was $.11 for both the
first quarters of 2003 and 2002.

Liquidity and Capital Resources

We continue to maintain a strong financial position. Cash flow provided by
operating activities totaled $1,585,307 in the first three months of 2003. Total
cash, temporary cash investments and marketable securities increased $826,901
during the same period, primarily as a result of the net income for the period,
a decrease in accounts receivable, and an increase in accrued income taxes,
offset somewhat by a decrease in accounts payable and accrued compensation,
repurchases of shares of our common stock totaling $419,400, and dividend
payments totaling $328,360. The $933,874 year-to-date decrease in accounts
receivable is primarily due to improved collection of receivables, and to lower
shipments in the first quarter of 2003 compared to the fourth quarter of 2002.
Inventory levels remained consistent between December 31, 2002 and March 31,
2003. The $214,500 year-to-

                                       -9-
<PAGE>

date decrease in current liabilities is primarily due to the decrease in accrued
compensation resulting from the payment of incentive bonuses in the first
quarter of 2003.

We have no long-term debt or material commitments for capital expenditures as of
March 31, 2003. Our plant and equipment would not require any major expenditures
to accommodate a significant increase in operating demands. We anticipate that a
combination of our existing cash, temporary cash investments and marketable
securities, plus an expected continuation of cash flow from operations, will
continue to be adequate to fund operations, capital expenditures and dividend
payments for the foreseeable future.

Critical Accounting Policies

Our estimates related to certain significant assets and liabilities are an
integral part of these consolidated financial statements. These estimates are
considered critical to the consolidated financial statements because they
require subjective and complex judgements. We consider our critical accounting
policies to be the policies applicable to allowance for doubtful accounts,
inventory reserves, and the recoverability of long-lived assets. These policies
are discussed in the section of the Management's Discussion and Analysis of
Financial Condition and Results of Operations entitled Critical Accounting
Policies contained in our Annual Report on Form 10-K for the year ended December
31, 2002. No material change occurred in these policies in the periods covered
by this report.

New Accounting Pronouncements

In June 2002, the FASB issued SFAS No. 146, ACCOUNTING FOR COSTS ASSOCIATED WITH
EXIT OR DISPOSAL ACTIVITIES, which supersedes Emerging Issues Task Force (EITF)
Issue No. 94-3, LIABILITY RECOGNITION FOR CERTAIN EMPLOYEE TERMINATION BENEFITS
AND OTHER COSTS TO EXIT AN ACTIVITY. SFAS No. 146 requires that a liability for
a cost associated with an exit activity or disposal activity be recognized and
measured initially at fair value only when the liability is incurred. EITF Issue
No. 94-3 requires recognition of a liability at the date an entity commits to an
exit plan. All provisions of SFAS No. 146 were effective for exit or disposal
activities that were initiated after December 31, 2002. We adopted SFAS No. 146
during the first quarter of fiscal 2003 with no material impact on our
consolidated financial statements.

Item 3.  Quantitative and Qualitative Disclosures About Market Risk
         ----------------------------------------------------------

Market Risk Management

Substantially all of our marketable securities are at fixed interest rates.
However, virtually all of our marketable securities mature within two years,
therefore, we believe that the market risk arising from the holding of these
financial instruments is minimal.

We currently sell our products and services in United States dollars;
accordingly, the exposure to foreign currency exchange risk is minimal.

There have been no significant changes since December 31, 2002.

Item 4.  Controls and Procedures
         -----------------------

a.   Evaluation of Disclosure Controls and Procedures. The Company's Chief
     Executive Officer and President, and Vice President, Treasurer and Chief
     Financial Officer, have evaluated the effectiveness of the Company's
     disclosure controls and procedures (as such term is defined in Rules
     13a-14(c) and 15d-14(c) under the Securities Exchange Act of 1934, as
     amended (the Exchange Act)) as of a date within 90 days prior to the filing
     date of this quarterly report (the Evaluation Date). Based on such
     evaluation, such officers have concluded that, as of the Evaluation Date,
     the Company's disclosure controls and procedures are effective in alerting
     them, on a timely basis, to material information relating to the Company
     (including its consolidated subsidiaries) required to be included in the
     Company's periodic filings under the Exchange Act.

b.   Changes in Internal Controls. Since the Evaluation Date, there have not
     been any significant changes in the Company's internal controls or in other
     factors that could significantly affect such controls.
