Walk-in constant temperature and humidity room
Product introduction:
The walk-in constant temperature and humidity room is suitable for low temperature, high temperature, high and low temperature change, constant damp heat, high and low temperature alternating damp heat test of the whole machine or large parts. The size and function of the studio can be changed according to user requirements; the shape is beautiful and generous; the scientific air duct design can meet the needs of different customers; the touch screen PLC program controller is adopted.
Performance and characteristics of walk-in constant temperature and humidity room:
1. It has a wide temperature and humidity control range, which can meet the various needs of users. Using a unique balanced temperature and humidity control method, a safe and accurate temperature and humidity environment can be obtained. It has stable and balanced heating and humidification performance, and can carry out high-precision and high-stable temperature and humidity control.
2. Equipped with a high-precision intelligent temperature regulator, the temperature and humidity are controlled by a full liquid crystal display 7751 programmable instrument (you can also replace the OYO LCD 5461 programmable instrument according to the needs of users).
3. According to functional needs, a computer can be selected for remote control.
4. The refrigeration circuit is automatically selected, and the automatic control device has the function of automatically selecting and operating the refrigeration circuit according to the set value of the temperature, so as to directly start the refrigerator and directly cool the temperature under high temperature conditions.
5. The inner door is equipped with a large observation window, which can easily observe the test state of the test product.
6. Equipped with advanced safety protection devices ---- leakage circuit breaker, over-temperature protector, phase loss protector, water cutoff protector.
