BB705 2.50 in (63.50 mm)

 This BB705 is a blackbody temperature reference source which is adjustable over the range from 100 to 1046°C (212 to 1915°F) and accurate to ±1°C, ±0.25% rdg. It has a built-in digital temperature controller to provide accurate, stable temperatures as well as to provide the temperature readings of the cavity. The heated cavity provides a target of known temperature and emissivity, and virtually any infrared pyrometer with a spot size diameter less than 44.5 mm (0.88") can be calibrated. Calibration setups are easy with the BB705. An independent NIST traceable probe and high accuracy panel meter provide temperature reference information. Both models come standard with an RS-232 computer interface which allows computer control of the setpoints for automatic test applications. A NIST traceable calibration certificate is also provided.
