DQY High-Altitude Low-Pressure Test Chamber

The high-altitude, low-pressure test chamber is used to determine the adaptability and reliability of components, materials, instruments, equipment, or other products in (high-altitude, low-oxygen, high-cold, plateau, etc.) environments. It can also meet the requirements of high and low temperature/constant temperature and humidity tests, and detect the parameter performance of various materials after changes in extreme environments such as heat resistance, cold resistance, dryness resistance, and humidity resistance.
