Delta, BC, June 2, 2008 - AirTest Technologies (TSXV:AAT) is pleased to announce the immediate availability of
the TR9294-Lon CO2 transmitter that is LonWorks® communicating. LonWorks® is a widely accepted sensor and
control communication standard that is used to easily and inexpensively network sensors and systems in all types
of new and existing buildings. In essence, Lonworks® provides one wire through which all components are
attached and can share common information, much like computers are easily connected to a network and to the

AirTest’s CO2 transmitters are used in buildings to save energy by controlling ventilation based on actual
occupancy. CO2 sensors are placed in a building much like thermostats and work with existing building control
equipment to better control fresh air ventilation. In most buildings 20% to 40% of heating and cooling is devoted
to conditioning outside air. “Virtually every existing building can save substantial energy with CO2 control, but
installation has been hindered by complications associated with integrating the sensors into existing building
systems” said George Graham, President of AirTest Technologies Inc., “Adding LonWorks® capability to our
sensors will mean that integration of AirTest CO2 transmitters into existing buildings will become much easier for a
large percentage of buildings.“ Many of the world’s major control companies now use LonWorks® which can
reduce installation and integration costs in both new and existing buildings..

AirTest has also recently joined the LonMark® association, which is dedicated to promoting “Open” control
systems that allow a wide variety of products made by different manufacturers, to easily talk to each other. This
group also tests and certifies devices to ensure they are 100% compatible with other LonWorks® products. The
TR9294-Lon is the only product of its kind that has LonMark® certification. Members of LonMark International
include the world’s leading manufacturers, integrators and users of control systems in a variety of industries,
including building automation, security, lighting, home/whitegoods, elevators/lifts, mass transit, semiconductor-
manufacturing equipment, consumer appliances, sunblinds, energy metering, construction, commercial real
estate, and industrial automation. Further information on LonWorks® and LonMark® certification of products can
