Basic Values of Thermoelectric Voltage in mV
What is the thermoelectric voltage of a type K or type J thermocouple?
In the table below you will find the thermoelectric voltage in mV for all thermocouple types. The thermoelectric voltage (in millivolts mV) for a type K thermocouple, for example, at a temperature of 300/°C is equal to 12.209 mV. The thermoelectric voltage at type J and a temperature of 300/°C is equal to 16.327 mV. The complete overview for all pairs and temperatures from -100 °C to +1700 °C can be found in the following table.
