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
