Abstract  The IR-RST standard radiation thermometers manufactured by CHINO Company, Limited, Japan, which can not display the temperature in real-time because the display unit hadn’t been designed. Therefore, an electrical measurement display device was designed which can measure the voltage, display the temperature and supply 24V DC voltage for this kind of infrared radiation thermometer. Calibrated a against high-level voltage power source and a voltmeter, the correction coefficients of the display instrument were got, the stabilitywas evaluated as well, the maximum relative error of voltage measurement can be achieved with in 0.03%. Assembled with a 0.65μm IR-RST radiation thermometer, it was calibrated against with a TG HT-9500 type high-temperature furnace as the source, the accuracy was better than 0.03% confirmed by the experimental results, and the extended uncertainty of the calibration system was 0.62℃ at 1 300℃.
