The i430 Flex is an AC current probe utilizing the Rogowski principle. The flexible and lightweight measuring head allows quick and easy installation in hard to reach areas, without batteries or an external power source.

Also available as a pack of 4 pieces of the i430 current clamp, to be used for high current measurements. The Flex clamp fits around bus bars and large or hard-to-reach conductors. This 4-pack is perfect for use with 3-phase tools such as the Fluke 430 series.
