Description

Fluke 374FC True-RMS Clamp Meter

The Fluke 374FC True-RMS Clamp Meter can be used to measure current levels up 600A (AC and DC). By equipping an optional Fluke iFlex probe it is also possible to expand this range further up to 2500A (AC only). Featuring DC as well as true-rms ac voltage and current measurements, and resistance measurement up to 6000Ω with continuity detection, the Fluke 374 is everything you need, plus a little more.
