                    ESCO ANNOUNCES FIRST QUARTER RESULTS AND
                    ----------------------------------------
                        REAFFIRMS FULL YEAR EPS GUIDANCE
                        --------------------------------


     St. Louis, MO, February 5, 2007 - ESCO  Technologies Inc. (NYSE: ESE) today
announced  its  results for the first  quarter  ended  December  31,  2006,  and
reaffirmed  full year  earnings  per share (EPS)  guidance of $1.50 to $1.65 per
share.  EPS for the first half of 2007 will be lower than previous  expectations
due to timing  issues  between  the first and  second  half of the  fiscal  year
explained in the Business Outlook section below.

     Within this release, references to "quarters" relate to the fiscal quarters
ended December 31 for the respective fiscal years noted.

     During the 2007 first  quarter,  the Company  recorded a net loss of ($1.4)
million,  or ($0.05)  per share on net sales of $98.8  million  compared  to net
earnings of $2.2  million,  or $0.08 per share on net sales of $90.6  million in
the first quarter of 2006. The primary drivers of the lower earnings in the 2007
first quarter include:

o    A $1.9 million increase in SG&A expenses consisting of the following items:
     an additional $0.8 million of sales and marketing  expenses incurred in the
     Test  segment  to  further  expand  its Asian  presence;  $0.5  million  of
     additional  costs at Hexagram and Nexus related to new product  development
     initiatives;  and at Corporate,  $0.4 million of professional fees incurred
     to support a research  tax credit  project and $0.2  million of  additional
     stock compensation expense.

o    An additional  $1.6 million of non-cash  amortization  expenses  related to
     identifiable  intangible assets from acquisitions  ($0.7 million),  and TNG
     software amortization ($0.9 million).

o    Lower sales of high margin defense spares and T-700  shipments,  along with
     additional  development  costs  incurred  on Space  programs at VACCO which
     accounted for a combined reduction in EBIT of $1.6 million.

o    Approximately  $3.1  million of Test chamber and  component  sales and $1.0
     million  of  profit  pushed  out of the first  quarter  as a result of site
     readiness timing issues ("parent building" general  contracting  delays) at
     five locations.

o    Approximately  $1.2  million  of DCSI  hardware  sales and $0.6  million of
     profit  pushed  into  January  as a result of  products  being  shipped  in
     December but not received by the customer until January.

Sales
- -----

     First  quarter 2007 sales were $98.8  million,  or 9.1 percent  higher than
first quarter 2006 sales of $90.6 million,  due to the acquisitions of Nexus and
Hexagram.

     Communications  sales of $30.0 million  increased  $10.9  million,  or 57.1
percent in the 2007 first  quarter  compared to the first quarter of 2006 due to
$10.0 million of additional  sales from Nexus and Hexagram ($11.2 million in the
2007 first  quarter  compared to $1.2  million of  Nexus-only  sales in the 2006
first  quarter for the one month period since Nexus' acquisition).  In the 2007
first quarter,  DCSI sales to COOP and public power  (Municipal)  customers were
$11.7 million compared to $11.4 million in the first quarter of 2006. DCSI sales
to investor-owned  utilities (IOU's) and sales of Comtrak SecurVision  products
increased slightly in the first quarter of 2007 versus 2006.

     Filtration  sales of $40.6 million  decreased $0.9 million,  or 2.2 percent
during the first  quarter of 2007 as  compared to 2006  primarily  due to a $1.4
million  decrease in Defense product sales at VACCO, a $0.4 million  decrease at
Filtertek primarily related to automotive  products,  partially offset by a $0.9
million increase in commercial aerospace sales at PTI.

     Test segment sales of $28.2 million decreased $1.8 million, or 6.0 percent,
during the first quarter of 2007 as compared to 2006 due to chamber installation
timing delays  resulting from several  "parent  building" site readiness  issues
mentioned above.

Earnings Before Interest and Taxes (EBIT)
- -----------------------------------------

     On a segment basis,  items that impacted EBIT dollars and EBIT as a percent
of sales ("EBIT  margin")  during the first  quarter of fiscal 2007 included the
following.

     In the Communications  segment,  EBIT for the 2007 first quarter was a loss
of ($2.8)  million,  compared  to a loss of  ($1.0)  million  in the 2006  first
quarter.  The primary  sources of the $1.8  million  decrease in EBIT dollars in
2007 include a $1.7 million decrease in EBIT at DCSI resulting from TNG software
amortization  ($0.9  million) and Pacific Gas & Electric  (PG&E)related  program
support costs.  Hexagram's  EBIT was also negatively  impacted by  approximately
$0.4 million  from  development  and initial  production  start-up  costs on new
products.

     In the  Filtration  segment,  the 2007 first  quarter EBIT was $1.8 million
(4.5  percent of sales)  compared to $4.1  million (9.9 percent of sales) in the
prior year first quarter.  This $2.3 million decrease in EBIT was due to: a $1.6
million  decrease at VACCO  resulting  from the  decreased  sales of high margin
defense  spares and additional  engineering  costs incurred on new Space product
development programs; a $0.6 million decrease at Filtertek resulting from higher
raw material costs and lower overhead absorption  resulting from the decrease in
domestic  automotive  sales;  and a $0.1 million  decrease at PTI resulting from
changes in sales mix and higher material costs.

     In the Test  segment,  EBIT was $2.2  million (7.8 percent of sales) in the
first  quarter of 2007  compared to $2.9  million in 2006 (9.7 percent of sales)
primarily due to the timing of sales noted above and the additional $0.8 million
of sales and marketing costs to support near-term sales growth opportunities.

     The Corporate  office  operating  expenses were $1.7 million  higher in the
first  quarter of 2007  compared  to 2006 and  included  $0.7  million of pretax
amortization of identifiable  intangible  assets related to  acquisitions,  $0.4
million of  additional of  professional  fees incurred to support a research tax
credit project, and $0.2 million of additional stock compensation expense.

Effective Tax Rate
- ------------------

     The  effective  tax rate in the first quarter of 2007 was a benefit of 56.9
percent and was favorably  impacted by $0.9 million of  additional  research tax
credits. The 2006 first quarter effective tax rate was 40.4 percent.

New Orders
- ----------

     New orders received in the 2007 first quarter were $146.3 million  compared
to $126.1  million  ($117.1  million  of new orders  plus $9.0  million of Nexus
acquired backlog) received in the 2006 first quarter,  resulting in a backlog of
$300.9 million at December 31, 2006.

     New orders  received  in the first  quarter of 2007  compared  to the first
quarter of 2006,  respectively,  were:  in  Filtration,  $45.3 million and $41.1
million; in Communications,  $61.8 million and $59.2 million (including the $9.0
million  of Nexus  acquired  backlog);  and in Test,  $39.3  million  and  $25.8
million.


     The 2007 new  orders  resulted  in  book-to-bill  ratios of 112  percent in
Filtration,  139  percent  in  Test  and 206  percent  in  Communications  for a
consolidated ratio of 148 percent.

     Significant orders in the first quarter of 2007 included:  $15.5 million of
orders with PG&E for the next phase of its advanced metering deployment;  a $6.3
million  automotive  test  chamber  order in  India;  a $3.4  million  aerospace
filtration order for Boeing 747 aircraft;  a $1.0 million chamber order in Korea
to test  RFID  systems;  and a $1.0  million  chamber  order in  Canada  to test
handheld communications devices.

Cash
- ----

     At December  31, 2006,  the Company had $28.0  million in cash and no debt,
compared to $36.8  million in cash and no debt at September  30, 2006.  The $8.8
million  decrease in cash in the 2007 first quarter reflects $11.1 million spent
on capital  equipment  and TNG  software  upgrades,  and $4.3  million  spent on
additional inventories to support near-term sales growth.

Chairman's Commentary - 2007 First Quarter
- ------------------------------------------

     Vic Richey,  Chairman and Chief  Executive  Officer,  commented,  "Although
first quarter operating results were below our expectations,  our entered orders
were strong.  Additionally,  certain  timing  issues that  occurred in the first
quarter will  negatively  impact the first half of the year. In  particular,  at
Hexagram  we  experienced   production   delays   associated  with  new  product
development and a later than planned  transition of manufacturing to third-party
subcontractors.  Also,  in the Test  business we  encountered  delays on several
projects due to customer  start-up and site preparation  issues.  As a result of
these  timing  issues and  relative to our  previous  first half  guidance,  our
forecast  for  improved  operating  performance  will be more  heavily  weighted
towards the second half of 2007.

     "All three  business  segments  contributed  to our strong  entered  orders
during the quarter  resulting in a consolidated  book-to-bill  ratio of 1.48. In
Communications,  orders  were in line with our  expectations  and we continue to
respond to a high level of requests for  proposals  (RFP's).  Our Test  business
continues  to  gain  significant  momentum  internationally,  especially  in the
emerging  markets as  evidenced by the recent  chamber wins in India,  Korea and
China.  Finally,  in  Filtration,  we  continue to see strong  aerospace  orders
supplemented by solid growth in the medical business.

     "I am pleased to report that our first quarter order momentum has continued
into the second  quarter.  In January,  Hexagram was selected by the Kansas City
Missouri Water Services  Department to be part of its meter automation  program.
Hexagram  technology  is expected to be added to  approximately  160,000  meters
throughout the Kansas City  metropolitan  area. We anticipate  revenues of $13.5
million over a three year  deployment  period  starting in the third  quarter of
fiscal year 2007.

     "During my visit to PG&E in January,  I received  positive  feedback on our
gas and electric hardware  deployment,  as well as the progress we are making on
our software development.  This feedback, combined with the first quarter orders
received  from PG&E,  reaffirms my belief that they are  committed to a full AMI
deployment.

     "In  summary, while I would like to be  able to  report improved  operating
results  for every  quarter of 2007 we did have some  weakness  relative  to our
expectations  in the first  quarter.  However,  I believe  our  strong  backlog,
combined with our new product development  programs,  supports both our improved
operating performance in the second half of the year and our long term plans for
profitable growth and increased shareholder value.

Business Outlook
- ----------------

     Statements contained in the preceding and following paragraphs are based on
current expectations. Statements that are not strictly historical are considered
forward-looking, and actual results may differ materially.

     The  Business  Outlook  described  below  does not  include  the  impact of
potential  acquisitions or  divestitures,  but does include the  amortization of
identifiable  intangible  assets  related to Nexus and Hexagram,  as well as the
amortization of the TNG software.

     Additionally,  refer  to the  "Business  Outlook  -  2007"  section  of the
November 14, 2006 earnings  release for a comprehensive  discussion of "Purchase
Accounting - Identifiable  Intangible Assets," "TNG Software  Amortization," and
the "PG&E Contract."

     The 2007 revenue and EPS estimates  described  below include  approximately
$25 million of sales and  approximately  $10  million of EBIT  related to DCSI's
portion of the PG&E contract which is subject to revenue deferral until delivery
and acceptance of TNG version 3.0 is achieved. Version 3.0 is currently expected
to be delivered in the fourth  quarter of fiscal 2007, at which time the Company
expects to recognize the cumulative  deferred  revenue on the units delivered up
to that date.

     The November 14, 2006 earnings release also contains  Management's  "Fiscal
2008  Preliminary  Long-Term  Outlook" and  "Chairman's  Commentary  on Business
Outlook."


Earnings Per Share - 2007
- -------------------------

     Management  estimates  of 2007 EPS  continue to be in the range of $1.50 to
$1.65 per share, which includes $9.1 million of pretax amortization  expense, or
$0.21 per  share,  related  to  purchase  accounting  intangible  assets and TNG
software.

     Several timing issues impacting certain large chamber deliveries within the
Test business along with accelerated  professional  fees spent in the first half
of the year have  negatively  impacted  the first six months  EPS  expectations.
Certain chamber deliveries  previously expected in the first six months, are now
expected in the second half of the year, and certain professional fees which had
previously been expected to be incurred ratably throughout 2007 are now expected
to be higher in the first half of the fiscal  year.  As a result of these timing
issues,  the total year expectations  remain  unchanged,  but the first half EPS
will be lower than previous expectations.

     For the first half of the year,  Management  now  expects EPS to be between
$0.15 and $0.20 per share, down from the previous  expectation of $0.25 to $0.30
per share.

     Stock option  expense for 2007,  which is included in the EPS guidance,  is
still expected to be in the range of $0.10 to $0.12 per share, or $0.03 to $0.04
per quarter.

     The tax rate for fiscal 2007 is now expected to be approximately 39 percent
compared to our previous estimate of 38 percent.

Revenues and EBIT Margins - 2007
- --------------------------------

     Management  expectations  for 2007 revenues and EBIT margins are consistent
with the expectations communicated in the November 14, 2006 earnings release and
are repeated here for convenience.

     Management expects 2007 consolidated revenues to increase  approximately 22
percent and be in the range of $555 to $560  million and the  consolidated  EBIT
margins  should be in the range of 11.5 to 12 percent  (including  the impact of
the amortization of identifiable intangible assets and the TNG amortization).

     On a segment  and  operating  unit basis for 2007,  Management  expects the
     following:

o    PTI sales are expected to increase  approximately 4.5 percent and should be
     between $48 and $49 million and EBIT  margins  should be in the range of 15
     to 15.5 percent.

o    VACCO's sales are expected to increase  approximately  8 percent with sales
     expected to be between $35 and $36 million and EBIT margins in the range of
     17 to 19 percent as the sales mix changes  between defense spares and space
     products.

o    Filtertek  sales are expected to increase  approximately 7 to 9 percent and
     be in the range of $102 to $104 million with EBIT margins in the range of 7
     to 8 percent.

o    The Test  segment  sales are expected to increase 7.5 to 8.5 percent and be
     in the range of $138 and $140  million and EBIT  margins in the range of 12
     to 12.5 percent.

o    The Communications  segment sales are expected to increase approximately 48
     to 50 percent and be in the range of $231 to $234  million and EBIT margins
     in the range of 18 to 20  percent.  Nexus  sales are  expected to be in the
     range of $16 to $18 million and EBIT margins should be in the range of 6 to
     7 percent.  Hexagram  sales are  expected  to be in the range of $60 to $63
     million  and EBIT  margins  should  be in the  range  of 22 to 24  percent,
     including the continued  investment in SG&A to support  engineering and new
     product  development as well as the expected  ramp-up of the PG&E contract.
     Sales of AMR  products  at DCSI are  expected to be in the range of $144 to
     $147  million  and do not  include  any  revenues in the first half of 2007
     associated  with the PG&E  contract  as software  delivery is not  expected
     until the fourth quarter of fiscal 2007.  DCSI's EBIT margin is expected to
     be approximately  20 percent  including  approximately  $7.0 million of TNG
     amortization costs. At December 31, 2006, the Company has approximately $43
     million in external TNG development  costs capitalized on the balance sheet
     in other assets, and is expected to incur another $10 million in costs over
     the next year. Additional non-TNG related engineering and development costs
     are being expensed as period costs.

o    Corporate operating costs for 2007 are expected to be in the range of $17.5
     to  $18  million  and  include  $2.1  million  of  pretax  amortization  of
     identifiable intangible assets related to Nexus and Hexagram.
