Environmental simulation warehouse

This test chamber is suitable for high temperature, low temperature, high and low temperature cycle test of products (machines), parts and materials, as well as constant damp heat and alternating damp heat test.

This test chamber can be used for the test of heat-dissipation test samples and non-heat-dissipation test samples. For the test of the heat-dissipation test sample, the heat dissipation power cannot exceed the cooling capacity of the test box, because the cooling capacity is a dynamic value, which varies with the temperature point.
