thermocouple

thermocouple
A device for measuring slight changes in temperature, consisting of two wires of different metals, one wire being kept at a certain low temperature, the other in the tissue or other material whose temperature is to be measured; a thermoelectric current is set up which is measured by a potentiometer. SYN: thermojunction.

ther·mo·cou·ple (thurґmo-kup″əl) a device used for measuring temperature differences, consisting of a pair of dissimilar electrical conductors (such as platinum and platinum-rhodium) joined in such a way that an electromotive force is developed by the thermoelectric effects when the junctions are at different temperatures. See also thermocouple thermometer, under thermometer.
