High-temperature black body calibration source BL679

portablehigh-precision

Stability ±0.1℃ or 0.1%rd (whichever is greater) Emissivity > 0.995 Aperture 50 mm diameter The BL679 is a ultra-high temperature blackbody calibration source utilizing a digital indicating temperature up to 1800℃. A precision thermocouple N 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.
