A potentiometer is a high precision instrument that measures voltage by comparing an unknown voltage to a standard one. This device was made by Leeds & Northrup Co., out of Philadelphia, in 1966. It was intended as a portable instrument to be used in labs for measuring the output of thermocouples, thermal converters, strain gauges, and other transducers. With its standard cell battery, it could also be a source of calibrated voltage.
