Fluke 325 True‑RMS Clamp Meter Review: Features, Specifications & Applications
Fluke 325 True‑RMS Clamp Meter — 400 A AC/DC, Temperature
The Fluke 325 True‑RMS Clamp Meter is a compact yet powerful electrical diagnostic tool designed for electricians, maintenance engineers, and HVAC professionals. It combines True‑RMS accuracy with AC/DC current measurement, voltage testing, temperature measurement, and capacitance capability in one versatile instrument.
Fluke 325 True‑RMS Clamp Meter — Compact Power for AC/DC
The Fluke 325 is the top of the Fluke 320 clamp‑meter series, adding True‑RMS plus AC and DC current measurement up to 400 A. With temperature and capacitance functions built in, it handles both electrical and HVAC tasks in one compact tool.
Its slim 30 mm jaw fits into tight cable runs, and the True‑RMS engine ensures accurate readings even on the distorted waveforms common in modern installations. A bright display and one‑hand operation make daily measurements fast and safe.
Electricians working on industrial panels, commercial electrical systems, and HVAC maintenance often need a meter that can measure current, voltage, and temperature quickly without switching between multiple instruments. The Fluke 325 solves this by combining the most important diagnostic measurements into one compact clamp meter.
