User manual
Datasheet
The BL682 is a low temperature black body calibration source utilizing a digital indicating temperature low to -50℃. A precision PT100 temperature sensor is embedded in the black body 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.
