High low temperature test chamber is a test equipment that simulates the temperature change in the natural environment by technical means to test the performance of the specimens.
It is mainly used to test the heat and cold resistance of specimens, and it is widely used in electronics, electrical appliances, communications, instruments, vehicles, plastic products, metals, food, chemistry, building materials, medical treatment, aerospace and other fields.
