                    AMETEK ACHIEVES RECORD QUARTERLY RESULTS
                  --REVENUES INCREASE 16%, NET INCOME UP 32%--


Paoli, PA, October 20, 2004 -- AMETEK Inc. (NYSE: AME) today announced third
quarter results that established quarterly records for sales, operating income,
net income and diluted earnings per share.

AMETEK's third quarter 2004 sales of $310.7 million were up 16% from the $267.8
million recorded in the third quarter of 2003. Operating income for the third
quarter of 2004 was $50.5 million, up 28% from the third quarter of 2003. Net
income of $29.0 million was up 32% from last year's third quarter and diluted
earnings per share were $.42 per share, up 31% over the same quarter of last
year.

"AMETEK performed extremely well in the third quarter, establishing quarterly
records for sales and earnings. This record performance was driven by strong
internal growth, continued operational improvements, and contributions from our
strategic acquisitions," commented Frank S. Hermance, AMETEK Chairman and Chief
Executive Officer.

For the first nine months of 2004, AMETEK sales increased 12% to $906.0 million
from $812.2 million in the same period of 2003. Operating income totaled $141.4
million, a 23% increase from $114.9 million earned in the first nine months of
last year. Net income for the first nine months of 2004 was $81.4 million, up
28% from $63.5 million in the same period of 2003. Diluted earnings per share
were up 26% to $1.18 per share for the first nine months of 2004.

ELECTRONIC INSTRUMENTS GROUP (EIG)

EIG's third quarter 2004 sales were $172.9 million, up 24% from last year's
level of $139.0 million. Third quarter group operating income was up 29% to
$32.1 million, versus $24.9 million in the same period of 2003. Group operating
margins were 18.6%, up from 17.9% in the third quarter of 2003.

"EIG had a tremendous quarter," noted Mr. Hermance. "The revenue increase was
driven by 8% internal growth and the contributions from the Taylor Hobson and
Chandler Instruments acquisitions. Operating income was up sharply, driven by
the top-line performance and the benefits of our operational excellence
initiatives across the Group."

ELECTROMECHANICAL GROUP (EMG)

EMG's sales of $137.8 million were up 7% from $128.8 million in the third
quarter of 2003. Third quarter group operating income of $24.0 million was up
11%, versus $21.6 million reported for the same period of 2003. EMG's operating
income margin in the third quarter of 2004 was 17.4%, compared with 16.8% in the
third quarter of 2003.

"EMG also had an excellent quarter. The revenue growth was driven by strong
performance in our differentiated businesses. Operating income was up 11% on the
addition of Hughes Treitler and our continued operational improvements across
the Group," added Mr. Hermance.

OUTLOOK

Mr. Hermance commented, "We are again raising our estimates for the year.
Full-year revenues are expected to be up low double-digits on the benefits of
our acquisition program and continued solid internal growth in each of our two
Groups. Earnings are expected to be approximately $1.59 to $1.61 per diluted
share, an increase of approximately 22% to 24% over 2003."

"Our fourth quarter 2004 sales are expected to be up low double-digits from last
year's fourth quarter on internal growth in both segments and the contribution
from the Taylor Hobson and Hughes-Treitler acquisitions. We expect our earnings
to be approximately $.41 to $.43 per diluted share, an increase of approximately
14% to 19% over last year's fourth quarter," concluded Mr. Hermance.
