WebHow many millivolts should a thermocouple produce? Thermocouples designed for residential gas appliances, such as fireplaces, water heaters and furnaces, are made for 30 Millivolts. The reading should be between 25 and 30. Anything under or hovering around the 20 millivolts mark means the thermocouple needs to be replaced. Select one of the 8 letter-designated thermocouple types from the console, type any voltage (mV) within the thermocouples range into the Thermocouple (mV) window and press calculate. The calculator will produce the NIST thermocouple table temperature value for that voltage along with the sensitivity or Seebeck coefficient (dV/dT).
