The combined environmental test equipment provides a temperature and humidity change environment. It can be for scientific research and production units. Such as aerospace, aviation, petroleum, chemical, electronics, and communications. At the same time, the electrical vibration stress test is carried out in the laboratory according to the regulations. It can conduct temperature, humidity, and vibration stress screening tests on machines, electrical appliances, instruments, and materials. Such experiments are used to assess product suitability or behavioral evaluation.
