              PLC Controller Constant Temperature And Humidity Test Chamber



PRODUCT INFORMATION

Constant temperature and humidity test chamber provides a wide temperature and humidity control range. It is using to simulate severe high temperature, low temperature or damp heat environment .Customer can select suitable models based on performance and test area capacity.
It is widely used in various industries, such as electronic instruments and meters, new materials, electricians, vehicles, metals, electronic products, aerospace materials , which may encounter environmental condition during transportation, storage, and in-using


STRUCTURE
 
1.1 Cooling System
1 The refrigerating system equips France Tecumseh, and uses environmentally friendly refrigerant (R404a). Adopting binary low temperature circuit system design, it is convenient to use different compressors for work in different temperature regions.
2 Temperature and humidity control using P.I.D + S.S.R system coordinated control with the same channel. It has the function of automatic calculation, which can immediately modify the temperature and humidity change conditions to make the temperature and humidity control more accurate and stable.
3 High-precision controllers of temperature and humidity. The relative temperature and humidity performance is accurately set and displayed with a resolution of 0.1℃.
1.2 Temperature and Humidification System
1 Temperature system using Nickel-chromium alloy high-speed heating electric wire;
2 High temperature system is completely independent;
3 The humidity system using stainless steel tube built-in nickel-chromium alloy high-speed heating electric wire and high-temperature magnesium oxide powder, which has fast response and long life;
4 The temperature and humidification system is completely independent, and humidity has automatic water supplement device.
