AC/DC Clamp Meters

About AC/DC Clamp Meters

Available in many different sizes, clamp meters are used to directly measure the current of a conductor without the need to physically break the circuit. Simply hook the tester's jaws directly around a measurement point such as a wire and you can test AC/DC current safely, quickly and easily.

Clamp meters vary greatly depending on their model and price. Higher priced clamps generally have larger jaws and wider measurement ranges, while lower-priced clamps are suitable for more basic electrical measurements. Many clamps also double up as multimeters, including the ability to measure additional parameters such as voltage and resistance by using included test leads.

Many manufacturers are now also starting to develop flexible clamp meters designed for use in difficult applications. Fluke's CNX range are one such examples of these testers; thanks to the inclusion of flexible clamps, the user can bend the clamp as necessary around a difficult conductor, making it significantly easier to gain measurements in areas where a normal clamp meter might not be feasible.
