High-precision black body calibration source BL-2050W

portable

The traceability of the BL-2050W infrared blackbody standard device for human body temperature measurement primarily relies on the temperature control and uniformity of the constant-temperature bath to achieve an exceptional emissivity index exceeding 0.999 for its blackbody cavity. The system consists of a portable constant-temperature bath cooled by semiconductor thermoelectric modules (for easy transportation), a human ear temperature blackbody cavity, a standard platinum resistance thermometer, and a high-precision digital temperature display. The blackbody cavity can be equipped with a standard bayonet mount, allowing users to select different types of blackbody cavities according to their specific requirements. - Operating Temperature: Antifreeze/Water: 15 ℃ to 55 ℃ (59°F to 122°F) - Working Area: Diameter 138mm (5.4"), Depth 300mm (15.7") - Wetted Parts: 304 stainless steel - Liquid Volume: Approximately 10 liters (2.64 gal) - Stirring Method: Jet stirring - Temperature Control Method: Fully digital PID control - Display Resolution: 0.001 ℃ - Temperature Stability: ±0.002 ℃ /10min - Temperature Uniformity: ±0.005 ℃ - Heating Time: 20 minutes from 25°C(77°F) to 45°C(113°F) - Cooling Time: 30 minutes from 45°C(113°F) to 35°C(95°F) - Operating Voltage: 110VAC ±10%, 60Hz (Customizable Technical Specifications) - Rated Power: Approximately 220W - Dimensions: 235mm (9.3") x 280mm (11") x 560mm (22") - Net Weight: Approximately 17 kg (37.5 lb)
