Thermocouple
NIST ITS-90 reference functions (Monograph 175) with cold-junction compensation. Inverse uses Newton–Raphson on the forward polynomial.
ANSI MC 96.1 plug · Yellow
90% nickel, 10% chromium
Large positive Seebeck coefficient and decent oxidation resistance to about 1,200 °C.
Positive leg of Type K and Type E. Furnaces, engines, general industrial use.
95% nickel, 2% manganese, 2% aluminum, 1% silicon
Stable against Chromel. It is magnetic.
Type K negative leg. Industrial temperature control.
General purpose — the one most labs stock
Usual range −200 to +1,250 °C · −328 to +2,282 °F
ITS-90 polynomials run -270 to 1372 °C.
Ice bath = 0 °C. If the meter already compensates, leave CJC at the reference it uses (often 0) or convert uncompensated millivolts with the actual cold-junction temperature.
