This pyrometer controller was made ca. 1958 and given to the Smithsonian the following year. A red and black tag on the front reads “MINNEAPOLIS Honeywell BROWN PYR-O-VANE." The scale reads from 0 to 1000, with divisions every 10, and inscription reading "INT. RES. 821 OHMS. SERIAL No. 860,137 COUPLE TYPE J (i.e.) DEGREES FAHRENHEIT CALIBRATED FOR 4-5 OHMS, EXT. RES." With the instrument is a wooden model of a furnace, green finish.
