Fluke Clamp Meter Selection Guide

Wires in tight compact spaces. Panels out of reach. Extra large conductors. We understand your workspace and have designed products for noise-free, reliable readings. Built on success, clamp meters designed by Fluke are known as workhorse clamp meters. With advanced performance, the clamp meter line is designed to be simple to use and gimmick-free.

Choosing your Clamp Meter

Buying a Fluke clamp meter not only requires looking at specifications, but also looking at features, functions, and the overall value represented by a meter’s design and the care taken in its production. Reliability, especially under tough conditions, is more important than ever. Fluke’s design engineers make a point of building these test tools not only electrically, but also mechanically, robust. By the time Fluke clamp meters are ready to be tossed into tool cases, they’ve undergone a rigorous testing and evaluation program. User safety should be a primary consideration in choosing a clamp meter—or any other piece of electrical test equipment. Fluke not only designs its clamp meters to the latest electrical standards, but each clamp meter is independently tested and then listed by certified testing labs such as CSA, TÜV, etc. Only with these certifications can you be assured an electrical tester meets these new safety standards.
