FLUKE-374 True RMS AC/DC Clamp Meter

The Fluke 374 True-RMS Clamp Meter delivers reliable, professional-grade performance for demanding electrical environments. Designed to handle complex signal conditions, this meter provides accurate AC/DC current and voltage measurements up to 600 A and 600 V. True-RMS functionality ensures accuracy when working with non-linear loads, making it ideal for industrial, commercial, and HVAC applications.

Compatible with the optional iFlex™ flexible current probe, the Fluke 374 allows expanded measurement capability up to 2500 A AC, offering improved access to tight or hard-to-reach conductors. Its robust ergonomic build supports safe one-handed operation—even while wearing PPE—while the large backlit display simplifies readings in low-light areas. Additional capabilities like inrush current capture, min/max/avg recording, and a soft carrying case make the 374 an essential tool in any electrician’s kit.
