I have designed a thermocouple meter for use for obtaining temperature readings from thermocouples. Its used together with the thermal chamber described elsewhere on this site. The design is done primarily as a programmable instrument, but it has a OLED display, so it can show the current temperature. The programming uses SCPI, the same type of programming strings that most newer (1990 forward) instruments use.
