Kelvin Double Bridge

Product Overview

The Maxwell Kelvin Double Bridge (Model KDB-2031) is a precision instrument used for measuring very low resistances with exceptional accuracy. It functions on the current balance technique, comparing an unknown resistance with a standard reference to eliminate errors from contact and lead resistances.

Also known as the Kelvin Bridge or Thomson Bridge, it is widely used in scientific laboratories, industrial testing facilities, and conductor resistance (CR) testing environments.
