We are the manufacturer of microcomputer constant temperature and humidity chambers, cosmetics chambers, display chambers, wine coolers, temperature and humidity chambers, dehumidifiers, wine cellars, mobile constant temperature and humidity machines, and microcomputer constant temperature and humidity testing machines. All of our products are CE-certified, with TAF reports of calibration, featuring high quality, high stability, and high specification in a perfect shape of an arc. As general wine chambers and cosmetics chambers lack humidity control, causing wine bottles and medicines to mold. At the moment the door of a chamber opens, the humidity goes into the chamber. If the chamber lacks the function of dehumidification, wine bottles and medicines will mold. The low humidity of wine chambers will cause corks to harden and wine to evaporate, affecting the quality of wine. Our products feature three displays of temperature and humidity, PID control, a temperature and humidity sensor made in the U.S., an abnormal time alarm, and a temperature and humidity recorder.
