Altitude Test Chamber can combine temperature and altitude environment with optional humidity for simultaneous environmental testing. It’s used in line aeronautics, aerospace, communications, information, electronics, electrical and so on. This combination of elements allows precise simulation of real-life condition a product might encounter at various altitude levels.
