KWGDS series introduction: this chamber is suitable for the product (complete machine), parts, materials to perform high temperature test, low temperature test, high&low temperature cycling test and temperature filtrating test(ESS). 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, and at the same time, higher humidity will also be affected by the condensation which is caused by the heat emission products.
