Spectrographic Analyzers Spectral Radiometers Heat Flux Meters The BL678A High Temperature Black Body Furnace is a benchtop calibration source designed to provide precise temperature calibration in the range of 100°C to 1200°C. Utilizing a precision thermocouple N sensor embedded in the black body emitter, the BL678A ensures high accuracy and repeatability. The temperature controller employs industry-standard PID algorithms to maintain the emitter temperature within 0.1°C of the set point, offering fast stabilization and reliable temperature control. Wide Temperature Range: 100℃ to 1200℃ High Emissivity: Greater than 0.995 for accurate radiation measurements Temperature Uniformity: Maintains a uniformity of ±0.15℃ Aperture Size: 50 mm diameter, compatible with most D(distance-to-spot) ratios Built-in Temperature Correction Function: Improves measurement accuracy Infrared Temperature Sensors Infrared Thermal Imaging Systems Balun Technology Co., Ltd Add: 1322, F/3, Bldg 1, 33 Zique Rd, Haidian, Beijing100095, China Temperature range Aperture Diameter Heated Emitter Shape Emissivity Display Resolution Control stability (10min) Uniformity Tube depth Control Method Temperature Sensor Power Supply Interface Heat up time Calibration Method Dimension w/o holder Net Weight 100℃ to 1200℃ 50 mm (1.97 inch) Closed end tube better than 0.995 0.1℃ 0.1℃ or 0.1%RD (whichever is great) 0.15℃ or 0.15RD(whichever is great) 290mm Digital PID Precision N thermocouple 220V AC / 2000WA RS232 90 minutes from ambient to 1200℃ Pyrometric standard calibration 300mm(W) x 370mm(H) x 570mm(D) 20 kg approx.
