Abstract :
A furnace was constructed to investigate the effect of temperature distribution on the EMF change caused by the inhomogeneity in each individual thermocouple. The EMF change of the inhomogeneous Pt/Pd thermocouple was observed by scanning the thermocouple in the temperature gradient region.
