The accompanying unaudited condensed financial statements have been
prepared in accordance with the instructions to Form 10-Q and do not

Sales

Sales of $26,870 for the quarter ended March 31, 1995 increased 14.2%
from the first quarter of 1994.  The increase occurred primarily in
replaceable products, which represented 44% of total sales for the first
quarter of 1995.

Gross Margin

Gross margin decreased slightly from 44.5% of sales in the first quarter
of 1994 to 44.3% of sales in the first quarter of 1995.  The decrease
was partially due to increased sales promotion activity, and partially
due to increased material costs.  

Operating Expenses

Operating expenses increased from 30.9% of sales in the first quarter of
1994 to 31.0% in the first quarter of 1995.  The increase occurred in
sales and marketing expense, including more extensive advertising as
well as additional sales personnel.  Administrative expense and
research, development and engineering expense were lower as a percentage
of sales in the first quarter of 1995 than in the corresponding period
of 1994.  The Company is consolidating the recently acquired Lakewood
Instruments operations with Ozone Research, both of which are in
Phoenix, to further improve operational efficiency.

Other Income

Other income increased by $435 from the first quarter of 1994 to the
first quarter of 1995.  The increase included $191 of gain on the sale
of investments and a $200 recovery from an insurance policy on a
previously recognized loss.  The remainder of the increase was due to
higher earnings on an increased investment portfolio.  

Income Taxes

The effective tax rate for the first quarter 1995 is 31.4% based on the
forecast for the full year.  This compares to 27.6% in the corresponding
period of 1994.  The rate for 1994 included the benefits of tax loss
carryforwards acquired with the Autotrol merger. 

Net Income

Net income for the quarter was $2,800, as compared to $2,371 for the
first quarter of 1994.  Net income per share was $0.22 per share, an
increase of 16% over the $0.19 per share reported for the same quarter
last year.  

Liquidity and Capital Resources

As of March 31, 1995, the Company had cash, cash equivalents and
marketable securities of $40,447 versus $37,076 at December 31, 1994. 
The current ratio was 3.9 at March 31, 1995, as compared to 3.7 at
year-end 1994. 

Inventory increased by $1,239 to $20,667 during first quarter 1995. 
Inventory stocking levels were increased to provide timely deliveries to
customers and support an increased level of sales.

In the second quarter of 1995, the Company acquired the land and
building used for its Milwaukee, Wisconsin operations for approximately
$3,000 in cash.  

The Company believes that its current cash and investments position, its
cash flow from operations, and amounts available from bank credit will
be adequate to meet its anticipated cash needs for working capital,
capital expenditures, and potential acquisitions during the foreseeable
future.
