An instrument for measuring differences in electric potential.
Essentially, this instrument balances the unknown voltage against a known, adjustable voltage. If the balancing is accomplished automatically, the instrument is called a self-balancing potentiometer. Potentiometers are frequently used in conjunction with thermocouples for measuring temperature.
