介绍
High – low temperature and low pressure test chamber is a simulation of high altitude, high altitude, (plateau area) climate for storage and transport reliability test, and can be simultaneously electrified on the test piece for electrical performance parameters of the test equipment. Applicable to the defense industry, aerospace industry automation components, automotive parts, batteries, flat panel display group industry and related products for high temperature, low temperature, height (not higher than 30,000 m above sea level or 45,000 m) and high and low temperature cycling test, temperature and altitude of the integrated test, high and low temperature test this chamber can be used for heat dissipation test specimens and non-heat dissipation test specimen test.
Safety & Protections
