High-Temperature Fixed Point (1100 to 2500 ºC) Black body Furnace

•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.
