Abstract: The pressure effect on the NiGr-NiCu thermocouple was measured at room and liquid nitrogen temperatures up to 20 kilobar. The results showed that the pressure effect on the thermo-emf of this thermocouple was enhanced by the pressure. From 0 to 20 kilobar and in the accuracy of 0.1 Kelvin the pressuer effect on the thermo-emf did not affect the temperature measurement.

Key words: high pz-essure, low temperature, NiCr-NiCu thermocouple, thermo-emf
