IR Black Body Temperature Calibrator BCAL 1202 is a Micro controller Based Precision “BLACK BODY” Temperature Calibrators Generates True Reference Temperature. The Temperature Controller of the Calibrators Uses a Auto Tune PID Controller Algorithm. This Response Closely Follows the Heating Curve of an Actual Thermal System. FOCUS the Unit Under Calibration (UUC) to be Calibrate to the target point given in BCAL 1202. Set the Temperature from the Touch screen TFT LCD display. Both True and set Temperature can be Read. <br/ >When Stabilization Occurs, Simply Read the Temperature and Re-Calibrate the Process System. BCAL 1202 Calibrator may be Used for Calibration of all Type of Non contact Thermometers and online Pyrometers above 500 to 1200°C range
