A device for accurate measurement of temperature difference between two junctions. A thermocouple consists of two dissimilar metals joined at two joints in a loop so that the difference in voltage can be measured. If the temperature of one junction is known, the other junction temperature can be calculated. Since voltage changes in proportion to temperature, the voltage difference indicates temperature differences.
