High, low, and low pressure test chamber

High, low, and low pressure test chamber

型号：XH-GDDQ-系列

This test chamber is suitable for conducting high and low temperature, altitude (not higher than 30000 meters or 45000 meters above sea level), as well as high and low temperature cycle tests and temperature height comprehensive tests on products (whole machine), components, and materials. During high and low temperature tests, this test chamber can be used for testing heat dissipation test samples and non heat dissipation test samples. For the test of heat dissipation test samples, their heat dissipation power cannot exceed the cooling capacity of the test chamber, as the cooling capacity is a dynamic value that varies with temperature points.
