The PR543 series uses antifreeze or alcohol as the working medium, and controlled by the PR2602 precision temperature controller module.PR453 has a touch screen that is clear and beautiful,. And it can automatically complete the cooling, freezing, heat preservation process according to the users set procedures.

PR533 is used for the verification, calibration and test of temperature measuring and controlling instruments and devices, such as temperature controller with electrical contacts, temperature switch, etc. It is especially suitable for the calibration of “transformation oil surface thermostats”and “transformation winding surface thermostats”. The bath temperature control range is usually at (0-160) °C, and the temperature can be changed at the required rate. And the bath also has a constant temperature function. Its constant speed heating rate is usually specified as 1 °C / min and its cooling rate is usually specified as - 1 ° C / min.

Feature: 1.Temperature control system adopts PID temperature control technology, precision can reach 0.01 ℃. 2. Air - cooled compressor is adopted for refrigeration with high speed and low noise. 3. Standard calibrated cartridge for thermometer, platinum resistance, thermocouple, etc 4. Inside groove adopts arc lateral mixing structure, the structure design of precision and enhance the uniformity of the temperature field, can reach 0.01 ℃. 5. RS232 or RS485 communication interface can be optional to realize data transmission with PC or PLC, remote control. 6. Standard calibrated cartridge for thermometer, platinum resistance, thermocouple, etc.

1. By using the PR2601 precision temperature controller module，Resolution is 0.001℃ and accuracy is 0.01% 2. The use of touch screen makes the process more convenient 3. Highly intelligent, only need to set the required temperature 4. Real-time display of heating and power curve 5. It can be calibrated by three-point temperature and traced back to the standard 6. Three sets of commonly used SV values can be predicted 7. AC power abrupt change feedback
