Comments on the second quarter

Vaisala's net sales in the second quarter developed favorably. Also
the operating profit and number of orders received were on a good
level. Exchange rates continued to affect the net sales in a negative
way.


Outlook for the remainder of 2008

Instability in the world economy and changes in the currency exchange
rates are expected to continue to affect the business. Due to the
structure of Vaisala's customer base, the Company's market situation
is expected to remain unchanged in 2008. We expect our net sales to
be slightly higher than in the preceding year and operating profit to
remain at the same level or be slightly higher than in the preceding
year. The market situation is expected to remain favorable especially
in Asia-Pacific.

Development projects aiming at long-term growth are continuing.


President and CEO Kjell Forsén on Vaisala's six month results:"Vaisala's second quarter was a good one. Our net sales developed
favorably, especially in the instruments and airport weather
solutions business areas. The number of orders received has also
grown, and for example the order book for weather radars is good.

Vaisala was able to grow despite the fact that the US dollar has
weakened by some 15 percent in the review period compared to the
corresponding period last year. In comparable currencies, our net
sales would have grown by nearly 13 percent, instead of the 5.7
percent in current rates. Nearly 40% of our net sales this year has
been USD based.

A particularly positive development was the growth of sales in the
Asia Pacific region by 24 percent. The region grew into the second
biggest market for Vaisala after Europe.

The result was somewhat burdened by the development projects aiming
at long-term growth."


Market situation, net sales and order book

Vaisala's market situation remains unchanged. The number of orders
received has developed positively during the first six months.
Vaisala's market-position also remains strong.

The value of orders received was EUR 121.9 (107.9) million, which is
12.9 percent more than in the corresponding period last year. In
comparable currencies, the value of orders received would have grown
by 19.2 percent. The number of orders received for the past 12 months
is EUR 242.4 million. The order book stood at EUR 95.6 (82.6) million
at the end of the review period. Of the order book, approximately EUR
27 million will be delivered in 2009 or later.

Net sales increased by 5.7 percent year on year, to EUR 106.5 (100.8)
million. In comparable currencies, Vaisala's consolidated net sales
would have grown by 12.8 percent.

Net sales developed most favorably in the Asia-Pacific region and in
Europe, but declined in North America and South and Central America.
 Net sales per region were as follows: Europe EUR 39.0 (34.8)
million, Asia-Pacific EUR 33.5 (27.8) million, North America EUR 30.8
(33.8) million, and Africa and South and Central America EUR 3.3
(4.4) million. Exchange rates affected especially the North American
net sales. In comparable currencies, the net sales there would have
grown by 4.7 percent.

Operations outside Finland accounted for 94 (96) percent of net
sales.


Performance and balance sheet

Operating profit for the review period was 13.9 percent of the net
sales, EUR 14.8 (15.1) million. Profit before taxes was 14.6 percent
of the net sales, EUR 15.5 (16.4) million. Net profit for the review
period was EUR 10.7 (11.8) million.

Vaisala Group's solvency ratio and liquidity remained strong. On June
30, 2008, the balance sheet total was EUR 212.7 (204.8) million. The
Group's solvency ratio at the end of the review period was 86 (85)
percent.

Vaisala's consolidated liquid assets totaled EUR 89.6 (87.0) million.


Research and development

Investment in research and development in the review period totaled
EUR 11.5 (10.4) million, representing 10.8 percent of the Group's net
sales.


Capital expenditure

Gross capital expenditure totaled EUR 5.0 (3.4) million. The
construction of a new enterprise resource planning (ERP) system for
the entire organization continues. Implementation will proceed in
phases, and will commence this year.


Changes in financial reporting

From the first Interim Report for 2008, Vaisala Group's business will
be reported in four segments, which are Vaisala Instruments, Vaisala
Measurement Systems, Vaisala Solutions and Vaisala Services.

All figures for 2007 have been changed to correspond to the new
reporting model, and are therefore comparable. The comparative
figures for 2007 have been published in a stock exchange release on
30.4.2008.


Vaisala Measurement Systems

Vaisala Measurement Systems consists of sounding, surface weather
system, thunderstorm system, wind profiler, and weather radar
business segments. Vaisala Measurement Systems' offering was
complemented by single products and systems from Vaisala Solutions.
Correspondingly, the lightning detection services were moved to the
Vaisala Services business area.

Vaisala Measurement Systems' net sales to customers outside the Group
decreased by 3.4 percent year on year, to EUR 40.5 (42.0) million. In
comparable currencies, the net sales would have grown by 2.8 percent.
Operating profit was EUR 4.5 (6.1) million.

Even though some of the delay caused by a temporary disruption in
production in the first quarter has been caught up, the soundings
business is still somewhat behind the comparable level a year ago.
The disruption is not expected to have a significant impact on the
total net sales of the business area in 2008.

The value of orders received was EUR 56.3 million and the order book
stood at EUR 45.6 million at the end of the review period.


Vaisala Instruments

Vaisala Instruments consists of humidity, barometric pressure, carbon
dioxide, dewpoint, oxygen, wind and optical measurement business
segments.

The instruments business has developed well despite of the weakened
US dollar. The division's net sales to customers outside the Group
increased by 8.8 percent year on year to EUR 35.2 (32.4) million. In
comparable currencies, the increase in net sales would have been 15.8
percent. Operating profit of the review period was EUR 12.1 (10.5)
million.

The sales of all the product lines in the instruments business have
developed very positively.

The value of orders received from external customers was EUR 36.1
million and the order book stood at EUR 8.8 million at the end of the
review period.


Vaisala Solutions

The focus of business area's offering is in comprehensive weather
observation solutions within aviation, traffic, meteorology and
hydrology. Therefore single products and systems were moved to the
Vaisala Measurement Systems business area. Additionally, the road
weather services were moved to the Vaisala Services business area.

Vaisala Solutions' net sales to customers outside the Group increased
by 52.1 percent year on year to EUR 18.2 (12.0) million. In
comparable currencies, the net sales would have been up by 59.7
percent. Operating profit for the review period was EUR -1.4 (-1.0)
million. Markets for aviation weather solutions have developed
particularly favorably.

The total value of orders received was EUR 19.1 million and the order
book stood at EUR 28.2 million at the end of the review period.


Vaisala Services

Vaisala's service offering has been centralized under the Vaisala
Services business area, which became operative at the beginning of
2008. Vaisala Services consists of two business segments, Product
Services and Observation Services.

Net sales to customers outside the Group decreased by 13.3 percent
year on year to EUR 12.5 (14.4) million. In comparable currencies,
the net sales would have been down by 3.9 percent. Operating profit
for the review period was EUR -0.2 (1.4) million.

The total value of orders received was EUR 10.4 million and the order
book stood at EUR 13.0 million at the end of the review period.


Personnel

The average number of employees in the Vaisala Group during
January-June was 1,150 (1,095). Some 37 (39) percent of the personnel
were based outside Finland.

Vaisala has two incentive plans; one based on the development of
sales and profitability and covering all employees, and another three
year plan based on the development of profitability and covering key
employees.


Near-term risks and uncertainties

No significant changes occurred in the risks and uncertainties
relating to Vaisala's business during the review period.

The most significant near-term risks and uncertainties relate to
changes in the global economy. Changes in purchasing activities,
currency exchange rates (with particular respect to the U.S. dollar),
supply chain management and production activities are the most
significant of these. Significant changes in subcontractor relations,
activities or operating environment may have a negative impact on
Vaisala's business. Vaisala monitors these risks and prepares for
them in accordance with the Company's risk management policy.

The Company is currently carrying out some significant improvements
in its research and development and sales organizations. These
changes lay the foundation for the successful execution of Vaisala's
new strategy. A new Group-wide enterprise resource planning system is
also under development. These efforts may constitute a short-term
risk regarding Vaisala's net sales and result.


Vaisala's share

The Company's Board of Directors had no valid authorizations for
increasing the share capital or issuing convertible bonds or bonds
