The BB704 is a blackbody temperature reference source which is adjustable over a range of 100 to 398°C (212 to 750°F) and accurate to ±0.8°C (±1.4°F) of the indicated temperature. It has a built-in digital temperature controller to provide accurate, stable temperatures as well as to provide the temperature readings of the target plate. The heated cavity provides a target of known temperature and emissivity, and virtually any infrared pyrometer with a spot size diameter of 102mm (4") or smaller can be calibrated. The compact, portable design allows for quick and easy calibration setups. Both models come standard with an RS232 computer interface which allows computer control of the setpoints for automatic test applications. A NIST traceable calibration certificate is also provided.
