The series of testing chamber is designed with a wide Damp Heat regulating range in conformity to National Standard GB/T2423.1, 2, 3, and 4: Test A: Low temperature testing method; Test B: high temperature testing method; Test Ca: Constant Damp Heat testing method and Test Db: alternating Damp Heat testing method for Electric/electronic Product Environment Test.
This type of testing chamber is designed in accordance
with National Standard GB/T10592, Technical Conditions for High/low Temperature
Testing Chamber and GB/T10586, Technical Conditions for Thermo-heat Testing
Chamber. Thanks to the ideal temperature &humidity control mode adopted---balanced
temperature & humidity regulating mode, it boasts of automatic acquirement
of high temperature/high Damp Heat testing environment.
