The BB982 Portable Blackbody Calibration Source allows for calibration of non-contact infrared thermometers over the temperature range -20°C to +125°C.
It is suitable for use as a primary radiation source for infrared thermometers.
Laboratory performance and low uncertainty calibrations are ensured by the combination of high emissivity and excellent temperature uniformity.
The digital temperature controller allows the block temperature to be set to any value from -20°C to +125°C.
A separate, built-in temperature indicator and included platinum resistance thermometer provide traceability of the true radiance temperature.
A three point traceable calibration certificate is included. UKAS calibration of the resistance thermometer is available, as is radiometric calibration.
Temperature stability and uniformity is provided by distributed heating technology and solid-state vibration-free cooling.
