IEC 68-2-1 Programmable Constant Temperature Humidity Test Chamber


IEC 68-2-1 Programmable Constant Temperature and Humidity Test Chamber


Brief Introduction:

This Programmable Constant Temperature and Humidity Test Chamber conforms to the standard requirements of IEC68-2-1 Test A: Cold; IEC 68-2-2 Tests B:Dry heat; MIL-STD.202F; MIL-STD-810D; IEC 68-2-3 Test Ca: Damp heat, steady state; IEC 68-2-30 Test Db: Damp heat, cyclic; MIL-STD-810D and etc. This test chamber is used to test the adaptability of electrical appliance, food, automobile, rubber and plastics, metal and other products under the high-low temperature and alternating damp-heat environments. It is mainly to test the cold resistance, heat resistance, heat resistance, humidity resistance, dry resistance of the sample.
