Portable blackbody calibration source, -23℃ to 155℃, 0.1℃ or 0.1%rdg stability, 65mm diameter tube, 0.995 emissivity, with 6.35mm diameter test hole of PRT
BL673 PORTABLE BLACKBODY CALIBRATION SOURCE
The BL673 is a portable blackbody calibration source utilizing a digital indicating temperature from -23℃to 155℃. A precision platinum RTD temperature sensor is embedded in the blackbody emitter, providing high accuracy and repeatability.
The BL673 is as easy to use as “point and shoot.” Simply set the desired blackbody temperature from the convenient front panel control buttons, wait a few minutes for equilibrium, and point the gun at the target. The radiated energy from the blackbody is measured by your IR thermometer. Simply compare its readings to the display on the blackbody and record the difference.
