Configuration of Stability Chamber

① Workroom	SUS304 high quality stainless steel plate, mirror material, acid resistant, corrosion resistant and easy to clean. a large transparent observation window and adopts high temperature tempered glass. The upper and lower position of the sample holder can be adjusted as required.
② Air circulation system	Low noise long axis fan motor and high and low temperature resistant stainless steel multi-wing impeller, so that the temperature and humidity inside the chamber is uniform and stable.
③ Heating system	It is composed of heating wire to provide heat for the chamber to achieve the set temperature conditions, and it is cooperated with the refrigeration system to achieve temperature control.
④ Cooling system	Composed of compressor, evaporator, condenser, expansion valve, capillary, etc., two sets of original imported refrigeration systems can automatically switch work to ensure long-term continuous operation of equipment.
⑤ Humidity system	Including humidifier, water tank, water pump, etc., can produce water vapor to increase the humidity in the chamber, to meet the test needs of different humidity environments.
⑥ Control system	According to the set value, the operation of refrigeration, heating, humidification and other systems is accurately controlled to achieve stable control of temperature and humidity, and it also has over-temperature, low-temperature alarm and temperature limit alarm system.
