The low-temperature standard blackbody furnace and the medium-temperature and high-temperature comparison blackbody furnaces are large-aperture blackbody furnaces for calibrating radiation thermometer, which were development in collaboration with the Metrology Research Institute.
A comparison calibration is performed using a standard radiation thermometer for each of the low-temperature standard blackbody furnace and the medium-temperature and falling-temperature comparison blackbody furnaces.
(Former name: Keikken-type comparative blackbody furnace)
- The cavity is shaped like a double cone, achieving high cavity emissivity at large openings.
- For low temperatures, comparative calibration is performed using a platinum resistance thermometer (sold separately) as the standard thermometer. For medium temperatures, comparative calibration is performed using a 0.90μm standard radiation thermometer (sold separately).
- Excellent stability
