High-Temperature

Fixed Point Blackbody Furnace

Model IR-R80 series
The IR-R80 is High-Temperature Fixed Point Blackbody Furnace utilizing metal-carbon
eutectic fixed points developed by National Metrology Institute of Japan (NMIJ). What the
IR-R80 has brought is high-temperature fixed point calibration at 2474ºC for Radiation
Thermometers, which was previously achieved until 1085ºC (Copper).
It consists of furnace body, and exchangeable fixed point cells for enabling various fixed
point calibrations.

FEATURES
Realizing high-temperature fixed point calibration for radiation thermometers by
utilizing metal-carbon eutectic fixed points.
Enable to fixed point calibration of standard radiation thermometer (0.65µm) by blackbody cavity of aperture diameter
of 3mm.
Prepare 7 kinds of fixed point cells from 1100 to 2500ºC (By exchangeable fixed point cells, single furnace has brought
calibration of 7 fixed points.)
Enable the power-saving feature by using cylindrical sheet heating element made of carbon-carbon fiber composite
materials.
Achieve long-term stability by employing fiber optic type radiation thermometer (0.9µm) as temperature control sensor.
