Humidity Control High Altitude Test Chamber Altitude Low Air-Pressure Testing
Humidity Control High Altitude Test Chamber Altitude Low Air-Pressure Testing
The high altitude test chamber can be used for the heat dissipation test sample and non-heat dissipation test sample test. For the test of heat dissipation test sample, 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, in different temperature and humidity points, the cooling capacity of the refrigeration system is also accompanied by changes.
