          AMETEK ACHIEVES RECORD FIRST QUARTER WITH NET INCOME UP 25%
                         --RAISES FULL-YEAR ESTIMATES--

Paoli, PA, April 21, 2004 - AMETEK, Inc. (NYSE: AME) today announced first
quarter results that established records for sales, operating income, and net
income.

AMETEK's first quarter 2004 sales of $291.4 million were up 9% over the same
period of 2003. Operating income for the first quarter of 2004 was $43.5
million, a 19% increase from the $36.7 million recorded in the same period of
2003. Net income in the first quarter of 2004 increased 25% to $24.7 million, or
$.36 per diluted share, from first quarter 2003 levels of $19.7 million, or $.29
per diluted share. Sales, operating income, and net income were quarterly
records.

"AMETEK had an excellent quarter," noted Frank S. Hermance, AMETEK Chairman and
Chief Executive Officer. "Better than anticipated internal growth in both our
Electronic Instruments and Electromechanical segments, plus contributions from
businesses acquired last year enabled us to grow the top-line by 9%. We captured
the leverage in our business model and significantly increased profitability,"
he commented.

"We had superb cash flow generation from our businesses during the quarter. Our
cash flow from operations totaled approximately $41 million, a 58% increase over
the first quarter of 2003. We are well on our way to another record year of
operating cash flow," he added.

ELECTRONIC INSTRUMENTS GROUP (EIG)

For the 2004 first quarter, EIG sales increased 13% to $150.6 million. Operating
income was $26.1 million, compared with $20.0 million in the first quarter of
2003, an increase of 31%. Operating margins for the quarter improved to 17.3%,
from 15.0% in the first quarter of 2003.

"EIG sales were up in the quarter due to contributions from Solidstate Controls
and Chandler Instruments, both acquired in 2003, as well as strength in our
process and industrial businesses. Strong operating results at our existing and
newly acquired businesses drove EIG margins up 230 basis points," said Mr.
Hermance.

ELECTROMECHANICAL GROUP (EMG)

For the first quarter of 2004, EMG's sales were $140.8 million, a 5% increase
over the same period of 2003. Operating income of $23.3 million was up 7% from
the $21.8 million recorded in the same period of 2003. Operating margins for the
quarter were 16.6%, compared with 16.3% in the first quarter of 2003.

"EMG had a solid quarter with our differentiated businesses posting excellent
sales growth. Operating margins were up as we brought the revenue increase to
the bottom line," noted Mr. Hermance.

2004 OUTLOOK

Mr. Hermance commented, "Given the improving economic environment, we are
raising our estimates for the year. We now expect full-year revenues to be up
mid to high single-digits on the benefits of our Chandler Instruments and
Solidstate Controls acquisitions and improved internal growth in both Groups.
Earnings are expected to be approximately $1.48 to $1.53 per diluted share, an
increase of approximately 14% to 18% over 2003, driven by strength in our
differentiated businesses, our continued focus on operational excellence, and
contributions from our 2003 acquisitions.

"Our second quarter 2004 sales are expected to be up mid to high single-digits
from last year's second quarter on internal growth in both segments and the
contribution from our 2003 acquisition of Chandler Instruments. We expect our
earnings to be approximately $.37 to $.38 per diluted share, an increase of
approximately 16% to 19% over last year's second quarter," concluded Mr.
Hermance.
