temperature humidity test chamber

SUS#304 Stainless Steel constant temperature humidity test chamber -40℃


Function and Application:
SUS#304 Stainless Steel constant temperature humidity test chamber -40℃  is mainly for testing and determining the parameters and performance of electrical, electronic products, chemicals and materials upon the change of the environment in high-temperature, low-temperature or constant test.It can simulate different environmental conditions (temperature and humidity) on a product or material, It's appropriate for testing material performance, such as resist heat, resist dry and resist cold. It is widely applicable to aircraft industry, automobileindustry,semiconductors,chemicals,pharmacy,foodstuffs,home appliance industry and scientific research field.
Structure and Characteristics:

1.temperature humidity chamber is composed of the chamber, refrigeration systems, heating systems, air circulation system and control system.
2.The working chamber is made of high quality SUS#304 stainless steel material,the outer shell adopts A3 steel plate,surface electrostatic spraying.
3.Insulation system uses superfine fiberglass wool or polyurethane foam so as to ensure the temperature of inside chamber.
4.Temperature and humidity control adopts Korean import TEMI880 programmable touch screen temperatureand humidity controller, with automatic calculation of PID function.
5.Adopts steam humidifying method, automatic water circulation loop,with functions of automatic filling water.
6.Refrigeration system adopts original France "Tecumseh" refrigeration unit and full sets of refrigeration parts.
7.Input mode PT100 sensor.
8.The system of heating up, heating down, dehumidifying, and humidifying can be operated independently so as to reduce the cost of testing, extend the operating life of the machine and decrease the failure rate.
