Overview
The following tables give the output voltage of several thermocouple (TC) types over a range of temperature in 5°C increments. In each case, the TC reference temperature is 0°C. The first-named material will be the positive terminal, as iron-constantan; the iron will be the positive lead when the reference temperature is lower than the measurement. The temperature is in °C and the output is mV. Each column is in 5°C increments from the temperature of that row.
