High-temperature black body calibration source BL681 series

The BL681 is an ultra high temperature blackbody calibration source system which utilizing a digital indicating temperature 800℃ to 3000℃. A platinum rhodium wire sensor is embedded in the blackbody emitter, providing high accuracy and repeatability. The 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. FEATURE • Temperature is up to 3000℃ • Emissivity is better than 0.996 • Reference blackbody and control blackbody is integrated together • Built-in closed loop cooling system, no need external cool water • Computer simulation designed control unit and blackbody source • Pre-set temperature section control ensures high stability TYPICAL APPLICATION • Infrared temperature sensors • Infrared thermal imaging systems • Spectrographic analyzers • Radio meters • Flux meter
