Temperature calibrator BL675A

thermalfor thermometersportable

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. FEATURE • Temperature range 50℃ to 500℃ • 120 mm big aperture diameter • 0.10℃ uniformity at 50℃ set point • Built-in temperature correction function • Robust design, easy to carry • Extral 8mm SPRT test hole APPLICATION • Infrared temperature sensors • Infrared thermal imaging systems • Spectrographic analyzers • Spectral radiometers • Heat flux meter
