Pyrometer black body calibration source 988

for thermal cameras

The 988 is a low cost Blackbody source introduced to meet customer requirements for a simple, cost effective but high accuracy calibrator for the calibration of thermal imagers and infrared thermometers used at temperatures around ambient. A 70 mm diameter ridged plate is heated or cooled with an internal solid state thermoelectric heat pump. The temperature of the plate can be set from 20°C to 45°C with a resolution of 0.01°C. Evaluation showed the advantages of fitting a stainless steel tube around the plate to give better uniformity and less sensitivity to draughts and ambient temperature effects.
