Gemini R 976

The Gemini R 976 portable Blackbody calibration source allows for calibration of non-contact infrared thermometers from 30°C to 550°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 30°C to 550°C.

Traceability of the radiance temperature is established by a separate, built-in temperature indicator and an included Platinum resistance thermometer.

A three point traceable calibration certificate is included in standard. UKAS calibration of the resistance thermometers is available in option.

Uniformity of the block is ensured by using distributed heating technology. 

Key features:

• Medium temperature radiation primary source: 30°C to 550°C
• Large cavity: 65 mm diameter
• Emissivity: > 0.995
