High low temperature/ low air pressure test chamber

Collect
Description:

High low temperature/ low air pressure test chamber

Application:

High low temperature low air pressure test chamber is mainly used in aviation, aerospace, information, electronics and other industrial sectors to determine environmental adaptability and reliability of electrical and electronic products (including components, materials and instruments) under the action of high, low temperature and low air pressure alone or at the same time, and can carry out the electrical performance parameters tests by powering on the specimen at the same time.
