Temperature Traceability

IR-R24, IR-R26, IR-R27 NRLM Type Comparison Blackbody Furnaces
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.

TabView Example - Basic From Existing Markup

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.
