WBE-DQY High and low temperature low pressure test chamber

This test box is suitable for high temperature, low temperature, height (not higher than 30,000 meters or 45000 meters above sea level) and high and low temperature cycle test and temperature-height comprehensive test for products (machines), parts and materials, high and low temperature 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.
