                      MOCON ANNOUNCES THIRD QUARTER RESULTS
                      -------------------------------------

MINNEAPOLIS, MN, OCTOBER 21, 2003 - MOCON, INC. (Nasdaq:MOCO) today reported
revenue and earnings for the quarter ending September 30, 2003.

Sales for the third quarter of 2003 were $4,778,000, a decrease of 2% compared
to $4,853,000 for the third quarter of 2002. Net income was $534,000, a decrease
of 1% compared to $537,000 in the third quarter 2002, and net income per share
was even at 10 cents (diluted) for both the third quarters of 2003 and 2002.
Nine-month sales increased 2% to $14,939,000 compared to $14,637,000 for the
first nine months of 2002. Net income for the first nine months of 2003 was
$1,750,000, up 1% compared to $1,740,000 for the first nine months of 2002, and
net income per share was 32 cents (diluted), a 3% increase over the 31 cents
(diluted) earned during the same period in 2002.

"Our results for the first nine months of 2003 were up slightly over 2002,"
commented Robert L. Demorest, MOCON President and CEO, "despite what appears to
be continuing slowness in capital equipment spending by many of our customers.
The overall increase was due primarily to increases in sales of our permeation
and weighing products, offset by decreases in sales of our sample preparation
and gas analyzer products. With approximately $6,398,000 in total cash, current
and non-current marketable securities, and no long-term debt, we are actively
looking for opportunities for profitable growth, and feel that we are
well-positioned to take advantage of such opportunities should they arise.

The quarter ended September 30, 2003 marks our 88th consecutive quarter of
profitability and over 15 years of consecutive quarterly dividend payments. We
as a Company are proud of both of these achievements, which reflect our ongoing
commitment to providing shareholder value."
