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. Item Furnace with temperature control system Item Fixed Point Metals Copper (Cu: 1085ºC) Iron - Carbon (Fe-C: 1153ºC) Cobalt - Carbon (Co-C: 1324ºC) Palladium - Carbon (Pd-C: 1492ºC) Platinum - Carbon (Pt-C: 1738ºC) Ruthenium - Carbon (Ru-C: 1953ºC) Rhenium - Carbon (Re-C: 2474ºC) Fixed Point Cells
