“SANSEL” Series BCAL 1502 is a Micro controller Based Precision Temperature Calibrators Generates True Reference Temperature. The Temperature Controller of the Calibrators Uses a Auto Tune PID Control Algorithm. 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 1502. Set the Temperature from the Touch screen display. Both True and set Temperature can be read. When Stabilization Occurs, Simply Read the Temperature and re-Calibrate the UUC.
