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.
