42A to 1000A AC Current Clamp Meters with Double Opening Jaw and Slim Profile to Get into the Narrowest Spaces

Hioki clamp on meters are best-in-class measuring devices incorporating Hioki’s expertise in current sensing technology. The 3280-10 and 3280-20 are our most popular clamp on meters, featuring a thin and compact clamp core that lets you get into the tightest spots.

True RMS vs. MEAN Value

Two ways to convert alternating current to RMS are “true RMS response” and “average rectified RMS response” (averaging). Both display the same value for a sine wave, but can display very different values for distorted waveform.
