Legally Certified Primary Standard Platinum Resistance Thermometer for Forensic Metrology

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.
