                     MOCON ANNOUNCES SECOND QUARTER RESULTS
                     --------------------------------------

MINNEAPOLIS, MN, JULY 22, 2003 - MOCON, INC. (Nasdaq:MOCO) today reported
revenue and earnings for the quarter ending June 30, 2003.

Sales for the second quarter of 2003 were $5,132,000, an increase of 4% compared
to $4,955,000 for the second quarter of 2002. Net income was $609,000, up 1%
compared to $605,000 in the second quarter of 2002. Net income per share was 11
cents (diluted) for both the second quarters of 2003 and 2002. Six-month sales
also increased 4% to $10,161,000 compared to $9,784,000 for the first six months
of 2002. Net income and net income per share were $1,216,000 and 22 cents
(diluted), respectively, for the first half of 2003, compared to $1,203,000 and
21 cents (diluted) during the same period in 2002.

"Sales and net income were up in both the second quarter and first half of 2003,
due primarily to increased sales of our permeation products," said Robert L.
Demorest, MOCON President and CEO, "offset somewhat by decreases in sales of our
sample preparation and gas analyzer products. We are pleased to be able to
report an overall increase in sales and profitability, despite a challenging
economic environment. In the second quarter we announced a $1,200,000 increase
in our stock repurchase program, bringing the program total to $3,200,000. With
approximately $6,977,000 in total cash, current and non-current marketable
securities, and no long-term debt, we believe that we are well-positioned to
take advantage of opportunities as they arise in the second half of 2003."

MOCON is a leading provider of instrumentation and consulting and laboratory
services to medical, pharmaceutical, food and other industries worldwide. See
