Product Description

The BL678 is a portable blackbody calibration source utilizing a digital indicating temperature ambient 300℃ to 1200℃ (572F to 2192F). 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.
