QD series introduction：This chamber is suitable for the product (complete machine), parts, materials to perform high temperature test, low temperature test, altitude(no higher than 30000m or 45000m ) test, high&low temperature cycling test and temperature-altitude integrated test. When performing high&low temperature test, this chamber can be used for the tests of heat emission samples and non heat emission samples. For the test of heat emission samples, the cooling power can not exceed the refrigeration capacity of chamber, because the refrigeration capacity is a dynamic value, which will change with changeable temperature.
