Portable blackbody calibration source, 50℃ to 500℃, 0.15%rdg stability, 120mm diameter plate, 0.95 emissivity, with 6.35mm diameter test hole of PRT
BL675A FLAT FLATE BLACKBODY CALIBRATION SOURCE
The BL675A is a portable blackbody calibration source utilizing a digital indicating temperature ambient 50℃to 500℃. A precision platinum RTD temperature sensor is embedded in the blackbody emitter, providing high accuracy and repeatability. The temperature controller uses the industry standard PID algorithms to control the emitter temperature to within 0.1℃of the set points.
The black body emitter mechanism uses a resistive heating device that provides a long life, short stabilization times, and stable temperature control.
