GLH 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(cooling start point from high temperature ≤90℃), constant temp.&humidity test and alternating temp.&humidity test. This chamber cannot be used for the test of heat emission samples. And when the temperature is higher than 90℃, the refrigeration system of the chamber cannot be opened for the cooling requirement.
