Part Code: CALsys 1700BB



CALsys 1700BB calibration source is a highly stable standard black body furnace for calibrating non contact IR thermometer for the wide temperature range of 500 to 1700°C. The unique feature of this black body furnace is large temperature controlled black body target with a diameter of 29 mm which offer large view area for IR thermometer. The emissivity of the target is 0.97(±0.01). The temperature of the calibrator is set and controlled by a self tuned PID controller with automatic super fine adjustment.
