Temperature and pressure test is one of the environmental reliability tests of products. With the development of the transportation industry, when the product is transported by air or sea, it will suffer a certain air pressure value, the air pressure value will change with the environment, in order to evaluate the air pressure tolerance of the product, the product needs to be subjected to low pressure test to evaluate the reliaility.
