NM-RTS Series Low-temperature Cooling Thermostatic Bath

This series of thermostatic bath is mainly used for the verification and calibration of resistance thermometer, low temperature thermocouple, liquid-in-glass thermometer, bimetallic thermometer, filled system thermometer, etc., and can also provide a constant temperature source for other experimental research work. The working mode of upper mixing with double bath is adopted to separate the verification working area from the heating and cooling mixing area of the thermostatic bath, reducing the working noise, improving the technical performance of the machine and expanding the effective working area. PT100 platinum resistance temperature sensor and intelligent PID regulator are adopted to realize automatic temperature control, with the characteristics of short transition time, long stability time and high reliability.
