NRLM Type Comparison Blackbody Furnaces IR-R24, IR-R26 High Temperature Comparison Blackbody Furnaces IR-R27
NRLM type comparison blackbody furnaces, which have been jointly developed with the National Research Laboratory of Metrology, are large opening blackbody furnaces for calibration of radiation thermometers, and a high temperature comparison blackbody furnace uses a standard radiation thermometer for comparison calibration.NRLM Type Comparison Blackbody Furnace
Features(IR-R24, IR-R26)
- The cavity is profiled as a double cone and the high emissivity is realized with a large opening.
- For low temperature, a platinum resistance thermometer (sold separately) is used as a standard thermometer.
- For medium temperature, a 0.9µm standard radiation thermometer (sold separately) is used for comparison calibration.
- Long-term stability
