Thermocouple. A device consisting of the junction of two dissimilar metallic conductors, such as copper and iron, which generate different currents when subjected to the same temperature. When this junction is connected to a third substance, the thermocouple generates a resultant current that can determine the temperature of the third substance or control an associated device.

Things to Consider When Purchasing This Product:
