The main specifications can be divided into 6 standard sizes and 10 different conditions. ★ The controller can be connected to the computer via the LAN interface. Users can design programs on the computer screen, collect test data and records, call program execution, remote control machine switch, USB and other functions. ★ Using the powerful air circulation of the multi-wing blower to avoid any dead corners and make the indoor temperature and humidity evenly distributed. ★ Complete safety protection device, if an abnormal situation occurs, the controller screen will automatically display the fault status, cut off the power switch, and provide troubleshooting methods. The constant temperature and humidity test chamber produced by Shenzhen Keming Technology Industrial Co., Ltd. is equipped with a variety of imported compressors from famous European and American companies. In order to achieve extremely low temperature tests on products, the company is equipped with a cascade refrigeration system. And the use of low-temperature grade R23 or R508B, high-temperature grade R404 or R507 "green" refrigerant, according to the US Environmental Protection Department standards, this type of refrigerant can be used after 2030, the ban date has not been determined; in order to make the refrigeration system Get better cooling effect. The company is also equipped with fully enclosed compressors produced by the world-famous French company TECUMSEH. For those who have higher requirements for equipment refrigeration, they use German Bitzer or DWM COPELAND. Semi-hermetic compressor.
