Simulated high-altitude test chamber

The high-altitude low-pressure test chamber is suitable for conducting high temperature, low temperature, altitude (simulated altitude: 0-5600m), high and low temperature cycle tests, and temperature altitude comprehensive tests on products (whole machines), components, and materials. It is usually used in the defense industry, aerospace industry automation components, automotive components, electronics, electrical components, plastics, chemical industry, food industry, pharmaceutical industry, and related products to simulate high altitude, high altitude, (high-altitude areas) climate for storage and transportation reliability tests under single or simultaneous high and low pressure, and can also test the electrical performance parameters of the test piece when powered on.
