This machine is a low-temperature constant-temperature water tank formed by combining a high-precision thermostat and a compressor refrigeration system with micro-processing technology and PID control. Its built-in refrigeration and heating system can meet different needs of users. This product is a high-precision self-control digital display temperature calibration device, which has the characteristics of good temperature stability, uniform temperature field, high temperature control accuracy, low noise, good reliability and long life. The device adopts PID temperature adjustment to realize automatic temperature control, compact structure, convenient operation and intuitive reading. The standard blackbody developed by our company is suitable for manufacturers to test non-contact infrared human body thermometers.
