DescriptionThe 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 RS-232 computer interface which allows computer control of the setpoints for automatic test applications. A NIST traceable calibration certificate is also provided.
