CALsys 500BB calibration source is a highly stable standard Portable Black Body Furnace for calibrating Non-contact IR thermometer for the wide temperature range of 50 to 500°C. The unique feature of this Portable Black Body Furnace is large temperature controlled black body Target with a diameter of 100 mm which offer large view area for IR Thermometer

The Emissivity of the target is 0.95(±0.01). The temperature of the Calibrator is set and controlled by A self-tuned PID controller with automatic super fine adjustment.
