Infrared thermometer calibration standards SANSEL Model BCAL 1202, Black body Calibrator is used to measure the accuracy and performance of non-contact Thermometers. Infra red thermometer & online pyrometer calibration is performed by comparison of the temperature measured by UUC and target temperature indicated by the calibrator or using standard pyrometer. Focus the Unit Under Calibration (UUC) to be Calibrate to the target point given in BCAL 1202. Set the Temperature from the Touch screen display. Both True and set Temperature can be read.
