The measuring appliance is equipped
with an advanced LCD touch screen, which can provide
multiple procedure setting in both Chinese and English
versions. The adoption of dialogue box Mac OS in programming
can make the operation precise and quick, and the cooling
system can run automatically as long as you pre-set
the temperature. The measuring device can display the
malfunctions in detail and make record of them, which
enable you to correct the problems as quickly as possible.
Furthermore, the device has the timing function which
can automate or stop running at any time.
This test chamber can satisfy
GB10592-89 “Technical conditions for high & low
temperature test chambers”, and GB10586-89 “Technical
conditions for interchanging test chambers”.
Adopting the standard of sense organ:
The sense organ is used to
test the temperature & humidity, which saves the
needs of using gauze to maintain it. It avoids the effect
of unqualified water since no water is needed in the
RH testing process. The independent use of humidifier
and purifier simplifies the structure. The distillation
purifier in the standard installationt can supply purified
water directly, which increases the reliability of device.

Profile of the product series:
Controlling mode: balanced temperature/humidity
control mode
Refrigeration mode: Unipolar
refrigeration (air swept type); and bipolar compound
refrigeration (air swept type)
Humidifying mode: the galvanothermy
mode of vapor generation
