The BL679 is a benchtop blackbody calibration source utilizing a digital indicating temperature ambient 500℃to 1500℃. A precisionthermocouple Ntemperature 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.
