Air Cold High & Low Temp Alt. Humidity Test Chamber For Wide Applications
Temperature humidity test chamber is use to test material heat,cold,dry resistance, humidity resistance.Suitable for electronics, electrical appliances, communications, instrumentation, vehicles, plastic products, metal, food, chemical, building materials, medical, aerospace and other products.

Features
The temperature controller of the high and low temperature alternating heat and humidity test chamber adopts TH7110 series widescreen panel liquid crystal display programmable temperature controller, which can be operated at fixed value or program, and the operation is simple and convenient. The refrigeration unit uses the French Taikang unit. The test box is equipped with an electrothermal coating vacuum observation window, which can effectively solve the condensation problem of the observation window. The test box adopts the integral integrated assembly structure, and the appearance is beautiful and generous.
.
