1、Calibration temperature can reach 400℃ heating, cooling speed is very fast

        DTZ-400BC suface probe calibrator / suface sensor calibrator  system has a very good rising and cooling speed, from room temperature to 400℃, only 30 minutes, from 400℃ to room temperature, 55 minutes, with rapid cooling device only 45 minutes, greatly improving the work efficiency.

2、Calibration plane diameter up to 130mm, meet most surface temperature sensor calibration requirements

      DTZ-400BC surface temperature calibrator plane diameter up to 130mm, enough to calibrate L-type sensors and various sizes and types of surface sensors, such as thermistor, film sensor, surface resistance thermometer, strip sensor, sticker thermocouple, etc.

3、An external reference platinum resistance thermometer can be installed to reduce the uncertainty of calibration

      In order to achieve the ultimate calibration accuracy, the design engineer specially reserved the thermometer jack at the bottom of the aluminum surface, you can insert a 3mm diameter platinum resistance thermometer as a standard for comparison calibration, greatly improving the calibration accuracy.

4、The calibration plane has excellent temperature uniformity and surface finish

     Surface sensors are often difficult to calibrate because it is difficult to find a flat, uniform surface temperature source. The measuring surface is made of "aerospace composite material coating" with high hardness, good wear resistance and high thermal conductivity, which can ensure good contact between the calibrated sensor and the surface temperature calibrator, thus reducing the calibration uncertainty.

5、Accurate temperature control, stable, small overshoot temperature

     The device provides a variety of parameter options for users to choose, including setting PID parameters of three different temperature segments, high, medium and low, inflection point between different temperatures, alarm temperature, etc.
