The three comprehensive test chambers mainly provide temperature and humidity change environment for aerospace, aviation, petroleum, chemical, electronics, communication and other scientific research and production units. At the same time, the electric vibration stress can be applied to the test products in the test chamber according to the specified period for users. The whole machine (or parts), electrical appliances, instruments, materials, etc. are used for temperature and humidity and vibration comprehensive stress screening tests in order to assess the adaptability of the test articles or to evaluate the behavior of the test articles. Compared with the single factor, it can more accurately reflect the adaptability of electrical and electronic products to changes in temperature, humidity and vibration composite environment during transportation and actual use. The defects of exposed products are new product development, prototype test and product qualification. An important test method essential to the whole process of the test.
Equipment composition: test box, motion connection system, control system, refrigeration / dehumidification system, heating / humidification system, air duct system.

Connection and conversion
Use the lift to change horizontal and vertical vibration
Environmental machine usage
Environmental machine can be used under horizontal and vertical vibration and without vertical horizontal vibration
The lift has the function of controlling the up, down, left and right of the environment machine, so the vertical platform of the vibrating table is fixed after the surface is fixed, and no action is required.
