A thermocouple device comprising two low mass dissimilar metal elements each being of relatively short length and each having a relatively narrow cross section along their lengths. The elements are provided with pointed ends for engaging and penetrating the surface of an object to be measured for its temperature. The two metal elements are disposed together such that their pointed ends taper toward each other to form a single, unitary, pointed end. The two elements are separated by a relatively thin layer of heat resistant, insulating material, and extend into and are secured in an insulating refractory member.
