FIG. 3 is a partial enlarged view of FIG. 2. In the figures, the same reference numerals as in FIG. 1 indicate the same devices. In this embodiment, a hole is made in the furnace wall 2' to install a blackbody temperature reference object adjacent to the transparent window 3 for temperature measurement.
As shown in FIG. 3, an embedded tube 7 having a temperature reference object 5 and a contact thermometer (thermocouple) 6 attached to its tip end is embedded as shown in FIG. The inner surface of the embedded tube 7 is coated with a black paint (for example, black carbon) 8 with an appropriate roughness, and the ratio d of the inner diameter d of the tube to the length t is set to 10 or more to meet the temperature measurement requirements. Stabilization is planned by converting it into a blackbody reactor. A temperature reference object (for example, black carbon) 5 is heated by the heat inside the furnace.
