The Temperature And Humidity Vibration Test mainly provides temperature and humidity change environment for scientific research and production units such as aerospace, aviation, petroleum, chemical industry, electronics, communication, etc. At the same time, the electric vibration stress can be applied to the test product in the test chamber at a prescribed period , For users to conduct a comprehensive stress screening test of temperature, humidity, and vibration on the whole machine (or parts), electrical appliances, instruments, materials, etc., in order to assess the suitability of the test sample or evaluate the behavior of the test sample. Compared with the effect of a single factor, it can more truly reflect the adaptability of electrical and electronic products to the changes of temperature, humidity and vibration in the environment of transportation and actual use, and expose the defects of product.
