Structure:
This machine adopts a closed chamber structure with the following
features:
A. It has an extremely wide temperature and humidity control range
to meet the various needs of users.
B. It adopts a unique balanced temperature adjustment and humidity
control mode to adjust the ideal temperature and humidity
environment. The heating and humidification capability are stable
and balanced, and the temperature and humidity control are
high-precision and high-stability.
C. Automatic selection of refrigeration circuit: The automatic
control device has the ability of automatically starting the
running refrigeration circuit according to the set value of
temperature, can start the cooling directly under the high
temperature state.
The refrigeration adopts the air-cooled condensing unit with fully
enclosed compressor (imported).
D. The door is equipped with an observation window, which is
convenient for observing the test state of the test sample.
