In a two wire thermocouple, a hollow tip is formed of the material of one of the thermocouple wires, the tip being adapted to extend into a medium the temperature of which is to be measured, both wires extending into a passage in the tip through an open outer end of the passage toward an inner end of the passage, one of the two thermocouple wires, of a material different from said tip, extending entirely through the passage and being welded at the outside of said tip to form a thermocouple junction and the other of the wires, of the same material as the tip, being welded to the tip at a place spaced from the junction.
