BL675A Big Area Flat Blackbody Calibrator

The BL675A is a portable blackbody calibration source utilizing a digital
indicating temperature ambient 50℃ to 500℃. 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. The emissivity is 0.95 and plat diameter is 120mm. It is suitable for most of D:S radiation thermometer.
