Configuration of Constant Temperature and Humidity Test Chamber

① Workroom	SUS304 stainless steel with good corrosion resistance and thermal conductivity. Equipped with double punch design sample holder, adjustable height, bearing 50KG each layer.
② Air circulation system	The circulating fan is installed on the top of the workroom, and the motor drives the fan to rotate, so that the air in the chamber forms a circulation flow to ensure the uniformity of temperature and humidity.
③ Cooling system	Composed of compressor,condenser, evaporator, throttling device. Compressor is the core of the refrigeration system, by compressing the refrigerant gas, so that its pressure and temperature rise.
④ Water Circulation and Automatic Water Supply	Continuous humidification is ensured through the internal water tank and pump circuit. Automatic water intake, maintaining a stable water level, reducing manual water replenishment, and ensuring long-term operation.
⑤ Control system	Regulate heating, cooling and humidity systems. Meantime, the controller can also realize the programming control of the test process, such as setting the temperature and humidity curve, the number of cycles, etc.
