Product Description

Dual Cavities Blackbody calibration source, -15℃ to 500℃, 0.1℃  stability, 65mm and 50mm diameter tube, 0.995 emissivity, with 6.35mm diameter test hole of PRT,  220V AC

 

BL675D DUAL BLACKBODY CALIBRATION SOURCE

 

 

The BL675D Dual Cavity Blackbody Calibration Source is easy to use, and makes calibration of infrared pyrometers with multiple temperature ranges faster than ever before by combining a hot and cold side in one unit.

The calibrators are simple to set and control. Merely input the desired Black Body temperature on the convenient front panel control buttons, let the unit reach the set temperature, wait a few moments to ensure stability, aim, and shoot. The radiated energy from the Black Body is measured by operator's IR thermometer. Compare the IR thermometer reading to the display on the controller and record the difference.
