Kelvin Contact Solutions

The term Kelvin Contact is derived from the English physicist Lord Kelvin who invented the Kelvin Bridge in 1861. The Kelvin Bridge is used to measure unknown electrical resistors below 1 ohm and is a modification of the Wheatstone bridge. The Kelvin contact solution by our supplier is using one of the pins to measure the current while the other is adjusting the applied voltage. As with all our products our engineers will adjust the product according to your specific needs.
