ITEM 2.02         RESULTS OF OPERATIONS AND FINANCIAL CONDITION

Today,  August 7, 2008,  the  Registrant is issuing a press  release  (furnished
herewith as Exhibit 99.1 to this report)  announcing  its fiscal year 2008 third
quarter financial and operating results. See Item 7.01, Regulation FD Disclosure
below.


ITEM 7.01        REGULATION FD DISCLOSURE

Today,  the Registrant is issuing a press release  (Exhibit 99.1) announcing its
fiscal year 2008 third quarter financial and operating  results.  The Registrant
will conduct a related Webcast  conference call today at 4:00 p.m. central time.
This  press  release  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",
"EBIT margin" and expected 2008 "EPS-Adjusted Basis".

The  Registrant  defines  "EBIT" as  earnings  before  interest  and taxes  from
continuing operations. 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 press  release  refers to expected  2008  "EPS-Adjusted  Basis" and EPS from
continuing  operations adjusted for "intangible asset amortization and inventory
step-up" exclusive of pre-tax  intangible asset amortization  expense related to
TWACS  NG  software,  purchase  accounting  intangible  assets  related  to the
Registrant's acquisitions within the past three years and the expense related to
the purchase  accounting  step-up of Doble Engineering  Company  inventory.  The
Registrant believes that the presentation of these operational measures provides
important supplemental information to investors regarding financial and business
trends  relating  to  the  Registrant's   financial  condition  and  results  of
operations.  The Registrant's management believes that these measures provide an
alternative  method for assessing the Registrant's  expected future  performance
that is useful because they facilitate  comparisons  with other companies in the
Utility  Solutions Group segment  industry,  many of which use similar  non-GAAP
financial  measures to supplement  their GAAP results.  The Registrant  provides
this information to investors to enable them to perform  additional  analyses of
present  and future  operating  performance,  compare  the  Registrant  to other
companies, and evaluate the Registrant's ongoing financial operations.

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

Sales
- -----

     Third  quarter 2008 sales of $157.7  million were 36.7 percent  higher than
third quarter 2007 sales of $115.4  million,  and  year-to-date  sales increased
40.3 percent to $427.8 million compared to $304.8 million in 2007.

     Utility Solutions Group sales of $93.7 million increased $39.7 million,  or
73.6 percent in the 2008 third  quarter  compared to the third  quarter of 2007,
primarily driven by $20.9 million of sales from Doble in the 2008 third quarter.
Fixed network RF AMI sales  increased $17.8 million,  or 165 percent,  primarily
due to higher gas AMI deliveries at PG&E. Fixed network  power-line system (PLS)
AMI sales decreased $5.0 million, or 12.7 percent,  driven by lower sales to IOU
customers  (primarily in Texas),  partially  offset by a 3.0 percent increase in
deliveries to COOP and public power  (Municipal)  customers  which totaled $30.5
million during the 2008 third quarter. Software sales and sales of digital video
security  products  increased  $6.0  million  in  the  third  quarter  of  2008.
Year-to-date  2008 sales of $247.5 million  increased  $114.3  million,  or 85.8
percent,  driven by Doble's sales of $52.0 million;  an RF AMI sales increase of
$33.9  million,  or 111.9 percent;  PLS AMI sales increase of $24.9 million,  or
28.0 percent; and a $3.5 million increase in sales of software and digital video
security products.

Test segment sales of $33.0 million in the 2008 third quarter
decreased  slightly  from the $34.6  million  of sales  recognized  in the third
quarter of 2007. This decrease is due to the timing of ongoing  domestic chamber
deliveries and slower than expected  installations.  Year-to-date,  Test segment
sales  increased  slightly  over prior year.

Filtration  segment  sales of $31.0  million  increased  $4.1  million,  or 15.4
percent  in the  third  quarter  of 2008,  and  year-to-date,  Filtration  sales
increased $6.7 million, or 9.0 percent. Sales increased across all product lines
with particularly strong results recognized in the aerospace end-markets.

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 2008 included the
following:

     In the Utility  Solutions Group,  EBIT for the 2008 third quarter was $17.7
million  (18.9 percent  of sales),  compared to $8.6  million  (15.9  percent of
sales) in the 2007 third quarter.  The $9.1 million increase in EBIT dollars and
as a  percent  of  sales  in the  2008  third  quarter  was  the  result  of the
significant  sales increases  across the segment as noted above.  The 2008 third
quarter also included higher TWACS NG software amortization compared to the 2007
third quarter ($2.9 million compared to $1.8 million).  Year-to-date,  2008 EBIT
was $41.5 million (16.8 percent of sales) compared to $11.9 million (8.9 percent
of sales) with the significant  increase in dollars and percentage  being driven
by the 86 percent increase in year-to-date sales within this segment.

     In the Test segment,  EBIT was $2.8 million (8.5 percent of sales) and $7.5
million  (7.6 percent  of sales) for the 2008  third  quarter  and nine  months,
respectively,  compared to the 2007 third quarter and year-to-date  EBIT of $2.0
million  (5.9 percent  of  sales)  and  $8.2 million  (8.5  percent  of  sales),
respectively.  The 2008 year-to-date EBIT included approximately $0.9 million of
non-recurring costs associated with the facility consolidation in Austin, Texas.
Additionally, year-to-date EBIT margins were lower due in 2008 due to changes in
sales mix involving  additional large chambers and fewer high-margin  components
sold versus 2007.

     In the Filtration  segment,  2008 third quarter EBIT was $5.2 million (16.8
percent of sales)  compared to $5.5 million (20.5 percent of sales) in the prior
year third quarter.  The decrease in EBIT dollars and margin is due to sales mix
changes at VACCO where fewer high  margin  defense  spares were sold in the 2008
third quarter. Year-to-date, 2008 EBIT was $13.8 million (16.9 percent of sales)
compared to 2007 EBIT of $12.7 million (16.9 percent of sales).

     Corporate  operating  costs  included  in EBIT were $5.5  million and $15.7
million in the third quarter and nine months of 2008, respectively,  compared to
$4.4  million  and $13.9  million in the 2007  third  quarter  and nine  months,
respectively.  The 2008  increases  are due to lower  royalty  income and higher
amortization  expenses related to purchase  accounting  identifiable  intangible
assets recorded at Corporate.

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

     The effective tax rate from  Continuing  Operations in the third quarter of
2008 was 24.4 percent compared to 33.3 percent in the third quarter of 2007, and
31.8  percent  compared to 21.0  percent for the nine month  periods of 2008 and
2007,  respectively.  The 2008 and 2007 tax rates were  favorably  benefited  by
various tax credits (i.e., export related benefits, research credits).

     The tax benefit  recognized in 2008 resulted from an analysis and amendment
of Federal income tax returns for the fiscal years 2001 through 2006.

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

     New orders received in 2008 were $159.1 million for the third quarter,  and
$453.5  million  year-to-date  resulting in a backlog at June 30, 2008 of $283.3
million.

     New orders  received  were $96.4  million in the Utility  Solutions  Group,
$34.1 million in Test, and $28.6 million in Filtration  during the third quarter
of 2008.

     Orders  from  PG&E  during  the 2008  third  quarter  were  $31.0  million,
including  $4.7 million  related to the RF electric  AMI order  announced in May
2008.  Subsequent to the third  quarter end, the Company  recorded an additional
$7.8  million of PG&E gas orders  related to its AMI  deployment,  resulting  in
year-to-date  PG&E  orders of $85.3  million.  Total PG&E firm order  quantities
since inception are 2.2 million units (1.6 million gas and 0.6 million electric)
and $140.0 million.

     While not included in the order amounts noted above, the Company previously
announced that its AMI technology has been selected by Idaho Power (estimated at
500,000  power-line  system  electric units,  $25 million),  New York City Water
(estimated  at 875,000 RF water  units,  $68.3  million),  and  Baltimore  Gas &
Electric (selected for RF pilot for gas and electric trial).

     Also subsequent to June 30, the Company announced that its Test segment was
awarded one of the largest contracts in its history. ETS-Lindgren signed a $16.7
million  contract with the National  Automotive  Testing and R&D  Infrastructure
Project  (NATRIP) in India to provide two  automotive  test  chambers to support
India's most significant automotive initiative undertaken to date.

Cash
- ----

     Net cash provided by operating  activities from  Continuing  Operations was
$51.2  million for the nine months  ended June 30, 2008.  At June 30, 2008,  the
Company had $22.8 million in cash and $230.5  million of total debt  outstanding
for a net debt position of $207.7 million.

Doble Purchase Accounting Items
- -------------------------------

     The annual  pretax  amortization  charge  related  to Doble's  identifiable
intangible  assets is expected to be approximately  $3.3 million for five years,
decreasing to $2.7 million for the remaining 15 years.

     Regarding tangible assets, Doble's finished goods inventory was required to
be "stepped up" under  purchase  accounting  by $1.7  million,  which results in
finished goods inventory being sold with no profit  recognized.  This results in
positive  cash flow,  but "lost"  profit of $1.3 million in fiscal 2008 and $0.4
million in fiscal 2009.

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

     Vic Richey,  Chairman and Chief Executive  Officer,  commented,  "I am very
pleased  with our  operating  performance  this  year as our  growth  in  sales,
earnings  and  entered  orders  continues  to  demonstrate   ESCO's  significant
resiliency against a challenging economic backdrop.  We continue to operate at a
level well above last year's sales,  EBIT,  EPS, cash flow, and entered  orders.
Our success in 2008 is evidenced by the double-digit  growth  percentages  noted
throughout our financials.

     "Our Utility Solutions Group continues to exceed our original  expectations
established  at the  beginning of the year,  and  considering  all of our recent
order activity and our AMI selections at Idaho Power,  New York City and others,
I'm very  enthused  about the way that our future  outlook is shaping  up.  This
momentum  leads me to  believe  that our  Aclara  brand  is  gaining  widespread
acceptance in the market.

     "Drilling  down  further  on the AMR / AMI  front,  I  continue  to be very
excited  about  the  increasing  opportunities  that  we are  addressing  in the
international  marketplace.   The  amount  of  international  piloting  activity
continues to expand both in numbers of utilities  expressing interest in our AMI
technology,  and in new  countries  which have come  forward  with  requests for
information  about  Aclara's  solution.  I remain  confident  that some of these
trials will ultimately lead to initial deployments over the next 12 months.

     "Doble  continues  to perform at an  exceptional  level and we expect it to
continue  this  pattern of growth and  profitability  well into the  future.  We
continue our plan to further Doble's presence in the international  market,  and
we have  validated  this strategy with our recent  acquisition of LDIC announced
this week."

     Mr. Richey  concluded,  "I am more confident than ever that our strategy to
drive  organic  growth  across  all  operating   segments  through  new  product
development and attention to costs, and supplemented by acquisition  activity to
allow  us  to  further  enhance  our  market  presence,  will  continue  to be a
significant  contributor to our stated goal of increasing long-term  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 excludes the Discontinued  Operations
of Filtertek  and the impact of any future  acquisitions  or  divestitures,  and
includes:  the  expected  operating  results  of  Doble  for  the 10  months  of
operations included in fiscal 2008 since the date of acquisition;  the impact of
the amortization of identifiable  intangible  purchase accounting assets related
to Aclara  Software,  Aclara RF, and  Doble;  the impact of the Doble  inventory
step-up  resulting  in  "lost"  profit,  and the  amortization  of the  TWACS NG
software.

PG&E Contract
- -------------

     PG&E's ongoing technology assessment activities may impact the timing and /
or receipt of future  orders from PG&E for its  electric  deployment,  and until
PG&E  completes this  evaluation  and determines  whether it will modify its AMI
project plan, the Company cannot  reasonably  estimate the timing or total value
of equipment orders that may be received.

     The Company has been in ongoing negotiations with PG&E related to a further
deployment of its Aclara RF electric AMI product.

     Additionally,  the  Company  is in  negotiations  with PG&E  related to its
existing  power-line  systems (PLS) contract to amend and redefine the remaining
