ITEM 2.02         RESULTS OF OPERATIONS AND FINANCIAL CONDITION

Today,  August 8, 2006, the Registrant is issuing a press release  (Exhibit 99.1
to this report) announcing its fiscal 2006 third quarter financial and operating
results. See Item 7.01, Regulation FD Disclosure below.


ITEM 5.02        DEPARTURE OF DIRECTORS OR PRINCIPAL OFFICERS;
                 ELECTION OF DIRECTORS; APPOINTMENT OF PRINCIPAL OFFICERS

Charles J.  Kretschmer,  a director  and  President  and COO of the  Registrant,
resigned as a director effective August 3, 2006. On that date, he also submitted
his  resignation as President and COO, to become  effective  September 30, 2006.
See Item 1.02 above. After September 30, 2006, Mr. Kretschmer will become a Vice
President  (a   non-"executive   officer"   position)  of  the  Registrant  with
responsibility  primarily  for  acquisition  /  divestiture  activity,  contract
manufacturing   for  the   Communications   segment,   selected  major  contract
negotiations  and  profit  improvement  initiatives.  Mr.  Kretschmer  has  been
President and COO of the Registrant since October 2002.

Victor L. Richey, Jr., currently Chairman and Chief Executive Officer ("CEO") of
the Registrant,  will also become  President  effective  September 30, 2006. Mr.
Richey has been CEO of the Registrant  since October 2002.  Since April 2003, he
has  also  been  Chairman.   Further   information   concerning  Mr.  Richey  is
incorporated  herein by reference to (i) the Registrant's  Proxy Statement dated
December 21, 2005 under the headings  "NOMINEES AND  CONTINUING  DIRECTORS"  and
"EMPLOYMENT  AGREEMENTS",  and (ii)  Registrant's  Form 10-K for the fiscal year
ended  September  30,  2005  under  the  heading  "EXECUTIVE   OFFICERS  OF  THE
REGISTRANT."


ITEM 7.01        REGULATION FD DISCLOSURE

Today,  the  Registrant  is issuing a press release  announcing  its fiscal 2006
third  quarter  financial  and  operating  results,  and will  conduct a related
Webcast  conference  call at 4:00 p.m.  central  time.  This  press  release  is
furnished  herewith  as  Exhibit  99.1,  and will be posted on the  Registrant's
website located at http://www.escotechnologies.com. It can be viewed through the
"Investor  Relations"  page  of the  website  under  the tab  "Press  Releases,"
although the Registrant  reserves the right to discontinue that  availability at
any time.


NON-GAAP FINANCIAL MEASURES

The press release furnished herewith as Exhibit 99.1 contains financial measures
and  financial  terms not  calculated  in  accordance  with  generally  accepted
accounting  principles  in the  United  States of America  ("GAAP")  in order to
provide  investors and management  with an alternative  method for assessing the
Registrant's operating results in a manner that is focused on the performance of
the Registrant's  ongoing  operations.  The Registrant has provided  definitions
below  for the  non-GAAP  financial  measures  utilized  in the  press  release,
together with an  explanation  of why management  uses these  measures,  and why
management  believes  that  these  non-GAAP  financial  measures  are  useful to
investors.  The press release uses the non-GAAP financial measures of "EBIT" and
"EBIT margin".

The  Registrant  defines  "EBIT" as  earnings  before  interest  and taxes.  The
Registrant  defines  "EBIT  margin"  as  EBIT as a  percent  of net  sales.  The
Registrant's  management  evaluates the  performance  of its operating  segments
based on EBIT and EBIT margin, and believes that EBIT and EBIT margin are useful
to investors to demonstrate the operational  profitability  of the  Registrant's
business segments by excluding interest and taxes, which are generally accounted
for across the entire  Registrant on a consolidated  basis.  EBIT is also one of
the measures used by management in determining  resource  allocations within the
Registrant and incentive compensation.

The  presentation of the  information  described above is intended to supplement
investors'   understanding  of  the  Registrant's  operating  performance.   The
Registrant's   non-GAP  financial  measures  may  not  be  comparable  to  other
companies' non-GAAP financial performance measures.  Furthermore, these measures
are not  intended  to replace net  earnings,  cash  flows,  financial  position,
comprehensive  income  (loss),  or any other measure as determined in accordance
with GAAP.

     Net earnings and earnings per share were lower in the third quarter of 2006
compared  to the prior year period as a result of changes in the  effective  tax
rate.  The  effective tax rate in the third quarter of 2006 was 31.3 percent and
was favorably  impacted by 6.0  percentage  points as a result of a $1.0 million
research tax credit recognized in the quarter.  The 2005 third quarter effective
tax rate was 15.7  percent,  and was  favorably  impacted  by a  true-up  in the
estimate of  foreign-sourced  income,  primarily  in Puerto  Rico.

Add One

     The primary drivers of the lower net earnings and earnings per share in the
2006 year-to-date period include:

o    An additional $3.0 million of non-cash  amortization  expenses  related to
     identifiable  intangible assets from recent acquisitions,  and TNG software
     amortization.

o    A significantly  higher effective tax rate in 2006 of 42.0 percent compared
     to 30.8 percent in 2005,  primarily  due to the $1.7  million  foreign cash
     repatriation charge recognized in the 2006 second quarter, along with lower
     foreign-sourced income in 2006 compared to 2005.

o    A $16.2 million increase in SG&A expenses comprised of the following items:
     $9.3  million from the current  year Nexus and  Hexagram  acquisitions;  an
     additional $5.2 million relating to engineering,  sales and marketing,  and
     new product  development in the  Communications  segment;  and stock option
     expense of $1.7 million.

o    Lower sales of high margin defense spares and T-700 shipments at VACCO, and
     lower sales of Comtrak's SecurVision video security products.

o    Fiscal 2005  year-to-date  results  included $1.6 million in sales and $1.9
     million of pretax earnings at Filtertek from the termination and settlement
     of a supply agreement  ("Supply  Agreement") with a medical device customer
     which was not repeated in 2006.

o    The above items were partially offset by improved operating results in 2006
     from  the  additional  sales  of RF Test  equipment,  commercial  aerospace
     products,  and  Automatic  Meter  Reading  (AMR)  devices for gas and water
     utilities.

Sales
- -----

     Third quarter 2006 sales were $123.6  million,  or 13.6 percent higher than
third  quarter 2005 sales of $108.8  million.  Acquisitions  accounted  for $9.5
million of the $14.8 million sales increase.  Favorable  foreign currency values
in the 2006 third quarter resulted in an additional $1.1 million of sales.

     Fiscal 2006 year-to-date  sales were $337.1 million,  or 5.6 percent higher
than the $319.3 million in sales for first nine months of 2005, primarily due to
the Nexus and Hexagram  acquisitions  which  contributed  $17.2 million of sales
since their respective  acquisition dates.  Unfavorable  foreign currency values
year-to-date in 2006 resulted in a $0.6 million negative sales comparison.

                                    - more -

Add Two

     Communications  sales of $49.2 million  increased  $18.1  million,  or 58.2
percent in the 2006 third  quarter  compared  to the third  quarter of 2005 as a
result of the following  items:  Sales to TXU Electric  Delivery (TXU) increased
$8.9 million to $10.2 million; $9.5 million of sales from the Nexus and Hexagram
acquisitions;  and  additional  sales to COOP  customers  which  increased  $1.9
million;  partially  offset by lower  sales to the Puerto  Rico  Electric  Power
Authority (PREPA) which decreased $2.9 million; and lower shipments of Comtrak's
SecurVision  video security  products which  decreased $0.8 million.  During the
2006 third quarter,  DCSI's sales to COOP and public power (Municipal) customers
were $25.0  million  compared  to $23.1  million  in the third  quarter of 2005.
Year-to-date  Communications  sales,  excluding  acquisitions,   decreased  $6.3
million in 2006 primarily due to the $8.5 million decrease in SecurVision sales,
partially offset by an increase of $2.2 million in sales of DCSI's AMR products.

     Filtration  segment sales of $42.6 million  decreased $2.1 million,  or 4.7
percent  during the third  quarter of 2006 compared to the prior year period due
to the following items: a $3.0 million decrease in sales at VACCO resulting from
lower deliveries of defense spares and T-700 valves; a net $0.2 million decrease
in sales at Filtertek  primarily due to the Supply  Agreement  settlement  which
contributed $1.6 million in sales in the 2005 third quarter; partially offset by
$1.1 million of  additional  sales at PTI due to the  continued  strength of the
commercial  aerospace  market.  Year-to-date  Filtration  sales  decreased  $0.6
million in 2006 primarily due to lower defense spares sales at VACCO,  partially
offset by increases at PTI and Filtertek.

     Test segment sales of $31.8 million decreased $1.2 million, or 3.6 percent,
during the third quarter of 2006 due to lower foreign embassy shielding projects
in the current year and the timing of completion  of a large chamber  project in
Japan.  Year-to-date Test sales increased $7.6 million, or 8.5 percent, to $96.5
million in 2006 as the overall wireless and electronics markets remained strong.


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 third  quarter of fiscal 2006 included the
following.

     In the  Communications  segment,  EBIT for the 2006 third quarter was $11.4
million  (23.2  percent of sales),  compared to $8.2  million  (26.4  percent of
sales) in the prior year third quarter.  The primary sources of the $3.2 million
increase in EBIT dollars  include:  a $3.6 million  increase from DCSI resulting
from the  increased  sales in the  quarter;  partially  offset by a $0.4 million
decrease  related  to  SecurVision.  Nexus  and  Hexagram's  combined  EBIT  was
breakeven and

                                    - more -

Add Three

excludes  the  amortization  of  identifiable   intangible   assets.   The  2006
year-to-date  Communications  segment EBIT  decreased  $8.3 million  versus 2005
primarily due to the decrease in SecurVision  sales described above,  changes in
the AMR related sales mix, and higher SG&A spending.

     In the  Filtration  segment,  the 2006 third  quarter EBIT was $5.2 million
(12.2 percent of sales), compared to $5.9 million (13.2 percent of sales) in the
prior year third  quarter.  This $0.7 million  decrease in the third quarter was
the result of: a $1.3  million  reduction  in EBIT at VACCO  resulting  from the
decreased sales of high margin defense spares;  partially offset by $0.9 million
increase at PTI related to  additional  sales volume  resulting  from  continued
strength  in the  commercial  aerospace  market.  Additionally,  the 2005  third
quarter and nine month EBIT amounts  included $1.0 million and $1.9 million from
the Supply  Agreement  settlement  at Filtertek  which was not repeated in 2006.
Year-to-date  Filtration  EBIT decreased  $4.0 million  primarily due to: a $3.8
million  decrease at VACCO related to lower defense spares sales; a $1.7 million
net  decrease  in EBIT at  Filtertek  resulting  from the  absence of the Supply
Agreement  settlement;  partially  offset by a $1.4 million  increase in EBIT at
PTI.

     In the Test segment, EBIT of $4.0 million (12.6 percent of sales) increased
in the third  quarter of 2006 from $3.3 million  (10.0  percent of sales) due to
favorable  changes in sales mix. The 2006 third quarter  included a lower amount
of foreign embassy shielding  projects,  which in the prior year incurred higher
installation  costs on  projects  located in  volatile  areas of the world.  The
year-to-date  EBIT  increased  $2.6 million over prior year, and the EBIT margin
improved  to 11.7  percent of sales from 9.8  percent of sales due to  favorable
leverage on the additional sales volume and a larger percentage of higher margin
component sales. In addition, EBIT was negatively impacted in the nine months of
2005 as a result of higher costs incurred on the foreign shielding projects.

     The Corporate  office  operating  expenses were $1.4 million  higher in the
third  quarter of 2006  compared  to 2005 and  included  $1.0  million of pretax
amortization of identifiable  intangible  assets related to recent  acquisitions
and $0.6  million of pretax  expenses  related to stock  options.  Year-to-date,
Corporate  expenses were $2.4 million higher than prior year and included:  $1.9
million of  amortization  expense;  $1.7 million of pretax stock option expense;
and higher professional fees; partially offset by the 2006 second quarter pretax
gain of $1.8 million  recognized on the reversal of the liability  related to an
indemnity owed to a former defense subsidiary.

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

     For the 2006  third  quarter,  the  Company's  effective  tax rate was 31.3
percent  versus 15.7 percent for the third  quarter of 2005.  The  effective tax
rate in the 2006 third quarter was favorably  impacted by 6.0 percentage  points
as a result of a $1.0 million research tax credit recognized in the quarter. The
2005 third quarter effective tax rate was favorably impacted by a true-up in the
estimate of foreign-sourced income, primarily in Puerto Rico.

     The 2006 year-to-date effective tax rate of 42.0 percent,  compared to 30.8
in 2005,  included a $1.7 million non-cash charge related to the repatriation of
$28.7 million of foreign cash in the 2006 second quarter.

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

     New orders  received  were $109.1  million and $106.2  million in the third
quarters  of 2006 and  2005,  respectively,  resulting  in a  backlog  of $260.0
million at June 30, 2006.

- ----

     At June 30, 2006,  the Company had $35.3 million in cash and no outstanding
debt,  compared to $20.9 million cash and no debt at March 31, 2006.  During the
third  quarter of 2006,  the  Company  generated  $14.4  million of cash.

Stock Repurchase Program
- ------------------------

     On August 3, 2006,  the  Company's  Board of  Directors  authorized a stock
repurchase program whereby Management may repurchase up to 1.2 million shares of
its  outstanding  common stock in the open market and otherwise  throughout  the
period ending September 30, 2008.

Chairman's Commentary
- ---------------------

     Vic  Richey,  Chairman  and  Chief  Executive  Officer,  commented,  "On an
operating basis,  our third quarter  performance in the aggregate was consistent
with our expectations. Our current view of the full year earnings remains within
the range of our previous guidance.

     "Perhaps the most  significant  event since our second quarter  release was
the California Public Utility  Commission's (CPUC) recent approval of PG&E's AMI
program, which includes equipping over nine million meters with a combination of
DCSI and Hexagram products.

     "Also of significance  with respect to building our AMR business,  in June,
Hexagram established a distribution alliance with Neptune Technology Group which
will  significantly  increase  our reach in the  stand-alone  water AMR  market.
Neptune is a market  leader in the water  industry and  accessing  its extensive
distribution  network should  significantly  accelerate our growth in the large,
but highly fragmented municipal water market. In my view, Neptune's desire to be
aligned with  Hexagram is further  evidence  that the shift we are seeing in the
water AMR market to fixed  network  solutions  will continue and we expect it to
accelerate in the future. We are seeing substantially  increased activity in the
major municipal markets, along with a heightened desire for the broader range of
benefits that can be derived from a fixed network solution.

     "As I have suggested  previously,  our top priority is to capitalize on the
extraordinary opportunities in the rapidly developing AMI/AMR market. The CPUC's
approval and the Neptune  alliance are important  milestones in that regard.  In
addition  to  continuing  our  efforts in support of the PG&E  program,  we have
established a structured  initiative aimed at enhancing our AMI offering through
the  integration of our  technologies  and  accelerating  our growth through the
unification of our sales and marketing efforts. We are also actively considering
other   opportunities   to  augment  our  product   suite  to  provide   further
differentiation  from  our  competitors.   While  AMI/AMR  remains  our  highest
priority,  we continue to expect solid  performance  across all our businesses."

Management Changes
- ------------------

     Mr. Richey continued,  "Effective August 3rd, we have reduced the number of
active  Directors on our Board from eight to seven,  and have reduced the number
of inside  Directors from two to one. This change was made in  conjunction  with
Chuck Kretschmer's resignation from our Board of Directors.  Chuck will continue
in his role as President and Chief Operating Officer through September 30, 2006,
after which time he will stay on with the Company  for an  indefinite  period of
time with narrower  responsibilities  primarily  supporting our key initiatives,
including M&A  activities  and various  profit  improvement  projects  currently
underway.

     "After September 30, I will assume the additional  title of President,  and
Chuck's previous  operational  responsibilities  will be assumed in part by Gary
Muenster,  our Senior Vice President and Chief Financial Officer, and in part by
our current Filtration management team.

     "After more than 28 years with the Company,  we respect  Chuck's  desire to
make more time for his other  interests,  and we appreciate  his  willingness to
continue to support some of our key initiatives after September 30."

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  includes  the  expected  operating
results of Nexus and Hexagram since their respective  acquisition dates, as well
as the amortization of identifiable intangible assets.

     The  Business  Outlook  for the  balance of 2006 does not  include  the tax
impact of any potential fourth quarter  repatriation  activities  related to the
approximately  $13 million of foreign cash  outstanding at June 30, 2006, or any
additional research tax credits.

Purchase Accounting - Identifiable Intangible Assets
- ----------------------------------------------------

     As described in the May 9, 2006 earnings release,  Management completed its
purchase accounting valuation related to the identifiable  intangible assets for
Nexus and Hexagram.  The total amount of identifiable  intangible assets subject
to  amortization  was $9.3 million.  The estimated lives for these assets ranged
from six months for certain  contracts  in  backlog,  to seven years for certain
patents and proprietary know-how.

     The  2006  pretax  amortization   charges  related  to  these  identifiable
intangible  assets were $1.0 million in the third quarter,  and year-to-date was
$1.9  million.  The pretax  charge in the fourth  quarter is expected to be $0.8
million, for a total fiscal 2006 pretax charge of $2.7 million. The total pretax
amortization  expense  for  fiscal  year 2007 is  expected  to be $2.1  million,
decreasing to approximately $1.0 million in subsequent years. These amortization
charges  are  recorded  in the  Corporate  operating  segment  in  the  attached
exhibits.

Earnings Per Share - 2006
- -------------------------

     Management  now estimates 2006 EPS to be in the range of $1.10 to $1.15 per
share. The May 9, 2006 EPS guidance range for 2006 was $1.05 to $1.15 per share.

     In fiscal 2006, the Company began expensing stock options. This expense for
2006 which is  included in the EPS  guidance,  is expected to be in the range of
$0.08 to $0.11 per share, or $0.02 to $0.03 per quarter.

     The effective tax rate for the fourth quarter of fiscal 2006 is expected to
be  approximately  38  percent  and does not  include  the  effect  of the above
mentioned fourth quarter foreign cash repatriation tax expense or any additional
research tax credits.

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

     Management expects 2006 consolidated revenues to be in the range of $455 to
$460 million and  consolidated  EBIT margins  should be in the range of 10 to 11
percent  reflecting the impact of the  amortization of  identifiable  intangible
assets.

     On a segment and operating unit basis for 2006,  Management now expects the
     following (as compared to the May 9, 2006 Business Outlook):

     o    PTI sales are  expected to be between $46 and $47 million  (versus $43
          to $45 million)  and EBIT  margins  should be in the range of 13 to 14
          percent (versus 12 to 13 percent).

     o    VACCO's  outlook  remains  unchanged with sales expected to be between
          $31 and $32 million and EBIT margins in the range of 20 to 21 percent.

     o    Filtertek  sales are expected to be in the range of $94 to $96 million
          (versus  $93 to $95  million)  and the  EBIT  margin  outlook  remains
          unchanged and should be in the range of 7 to 8 percent.

     o    The Test segment outlook remains  unchanged with sales expected in the
          range of $126 and $129  million and EBIT  margins in the range of 10.5
          to 11.5 percent.

     o    The  Communications  segment  outlook  remains  unchanged  with  sales
          expected to be between  $156 and $159  million and EBIT margins in the
          range of 18 to 20 percent.  Nexus sales since the date of  acquisition
          (10 months) are  expected to be in the range of $10 to $12 million and
          EBIT should be  slightly  negative.  Hexagram  sales since the date of
          acquisition  (8 months) are  expected to be in the range of $17 to $19
          million and EBIT margins  should be in the low single  digits based on
          the  significant  investment in SG&A to support sales and marketing 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 $121 to $122
          million  and do not  include  any  revenues  associated  with the PG&E
          contract as software  acceptance is not expected until the latter part
          of fiscal 2007.  DCSI's EBIT margin is expected to be 24 to 25 percent
          including  approximately  $2.1  million  of costs as a result  of DCSI
          beginning to amortize the capitalized development costs related to the
          TNG software.  TNG has been in development with a third party software
          contractor for the past two years.  TNG is being designed and deployed
          to efficiently handle the additional levels of communications dictated
          by the size of the service territories and the frequency of reads that
          are required under time-of-use or critical peak

          pricing  scenarios  needed to meet the requirements of large IOUs. The
          Company  has  incurred  approximately  $35  million  in  external  TNG
          development  costs  through June 30,  2006,  which are included on the
          balance sheet in other assets,  and is expected to incur another $7 to
          $12 million in costs over the next two years. TNG amortization expense
          for  fiscal  2006 is  expected  to be  $2.1  million  and for  2007 is
          anticipated  to be  approximately  $7.0  million.  Additional  non-TNG
          related engineering and development costs are being incurred as period
          costs.

     o    Corporate  operating costs for 2006 are expected to be in the range of
          $15 to $16 million and include the  following  items:  $2.7 million of
          pretax amortization of identifiable intangible assets related to Nexus
          and Hexagram; the pretax costs related to the adoption of stock option
          expensing   which   began  in  fiscal  2006  and  is  expected  to  be
          approximately  $2.2 to $2.4  million;  partially  offset  by the  $1.8
          million  pretax  gain   recognized  in  the  second  quarter  of  2006
          associated with the reversal of a liability  connected with the legacy
          defense contract noted above.
