The quality of the environment not only has a great impact on people, but also has a great impact on instruments, tools, and electronic products. What kind of environment is suitable for human habitation? Temperature: 20-26℃, humidity: 40-60%, air composition: 78% nitrogen, 21% oxygen, 0.2% carbon dioxide and other gases. What kind of environment is suitable for the operation of instruments and electronic products? A constant temperature and humidity testing chamber can solve this problem. It can test the adaptability of batch or large parts, semi-finished products or finished products when they are stored, transported and used in high and low temperature, humid and hot environments, and the temperature range and humidity range of detection can be modified and customized according to needs.
