Refrigeration constant temperature tank is a high-precision automatic control thermometer verification device, it has the characteristics of good temperature stability, uniform temperature field, high temperature control accuracy, etc., using imported fully enclosed compressor refrigeration system, precision temperature controller according to PID regulation law to achieve automatic temperature control, compact structure, easy to operate. This series of thermostatic bath is mainly used for the verification and calibration of thermal resistance, low-temperature thermocouple, glass liquid thermometer, bimetallic thermometer, pressure thermometer, etc., and can also provide a constant temperature source for other experimental research work. The upper stirring working mode of double tank body is adopted, which separates the verified working area from the heating and cooling mixing of the constant temperature tank, reduces the running noise, improves the technical performance of the machine, and expands the effective working area. The intelligent PI regulator of Pt10 platinum resistance temperature sensor is adopted to realize automatic temperature control, which has the characteristics of short transition time, long stability time and high reliability.
