1000L High Altitude Test Chamber Import Components Vacuum Test Chamber
The test chamber can be used for the test of heat dissipation test samples and non-heat dissipation test samples. For the heat dissipation test sample test, the heat dissipation power can not exceed the cooling capacity of the refrigeration system of the test chamber, because the control of temperature and humidity is a dynamic balance process, at different temperature and humidity points, the cooling capacity of the refrigeration system also changes.
