High-temperature black body calibration source BL677A

high-precision

Stability ±0.1℃ or 0.1%rd (whichever is greater) Emissivity > 0.995 Range 50℃~700℃ Aperture 65 mm diamter The BL677A is a benchtop blackbody calibration source utilizing a digital indicating temperature ambient 50 to 700℃. 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.
