Portable blackbody calibration source, Ambient +10℃ to 500℃, 0.1℃ or 0.1%rdg stability, 50mm diameter tube, >0.995 emissivity, 220V AC
BL676 PORTABLE BLACK BODY CALIBRATION SOURCE
The BL676 is a portable blackbody calibration source utilizing a digital indicating temperature ambient 35℃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.
