Fixed Point Black Body Furnace Lineup from In point to Cu point Realization of a high quality plateau Fixed point black body furnace, model : IR-R0A is a highly precise fixed point black body furnace that can use for the Temperature Standard for radiation thermometer. IR-R0A has 6 kinds of fixed point cell from In (157° C) in low temperature to Cu(1085° C) in high temperature. Furthermore, easily ejectable and replaceable heater unit and fixed point cell design. IR-R0A has been developed with NMIJ (National Metrology Institute of Japan) and is able to utilize for temperature standard. It is effective for fixed point calibration of the radiation thermometer for standards (model : IR-RST series by CHINO Corporation) in particular. ■ Feature •Realization of a good plateau by the improvement of the temperature distribution • Lineup In - Cu point •Changeable to other fixed points by cell exchange easily •Compact (184x370x360mm) and lightweight (13kg) ■ MODEL IR-R0A •Fixed point cell In point : 156.60° C Sn point : 231.93° C Zn point : 419.53° C Al point : 660.32° C Ag point : 961.78° C Cu point : 1084.62° C
