Constant temperature and humidity test chamber:
The constant temperature and humidity test chamber is a highly precise testing equipment that can perform constant humidity and temperature performance testing on products under simulated natural environmental conditions to evaluate their performance, stability, and durability. This equipment consists of five major systems, including control system, refrigeration system, heating system, humidity system, and air circulation system. These systems belong to two major areas: electrical and mechanical refrigeration. The control system is the core of the test box, which determines important indicators such as the temperature rise and fall rate and accuracy of the test box.
