constant temperature and humidity test machine, constant
temperature and humidity test chamber, programmable hot and humid
alternating test chamber, constant temperature machine or constant
temperature and humidity chamber, used to test the performance of
materials in a variety of environments and test a variety of
materials heat resistance, cold resistance, dry resistance,
moisture resistance performance. Suitable for electronics,
electrical appliances, cell phones, communications, instruments,
vehicles, plastic products, metal, food, chemical, building
materials, medical, aerospace and other products for testing
quality

Control Characteristics:
The control system of the test chamber can be said to be the heart
of the whole equipment, in charge of refrigeration, heating,
humidity control, circulation, control and other powers.
In terms of refrigeration, the compressor is imported from Germany.
Refrigeration system consists of high temperature part and low
temperature part, each part is a relatively independent
refrigeration system. The evaporation of refrigerant in the
high-temperature part absorbs heat from the refrigerant in the
low-temperature part and vaporizes; the evaporation of refrigerant
in the low-temperature part absorbs heat from the object to be
cooled (the air inside the testing machine) to get the cold
quantity. The high-temperature part and the low-temperature part
are linked by an evaporative condenser, which is both the condenser
of the high-temperature part and the condenser of the
low-temperature part.
