Fluke 325 True-RMS Clamp Meter

The Fluke 325 crowns the Fluke 320 range of commercial / residential clamp meters. With True RMS measurement, its slim design and 30mm jaw opening, along with DC current and frequency measurements, the Fluke 325 is a great troubleshooting tool, saving you having to buy and carry multiple tools.

The 325 is designed to verify the presence of load current, AC voltage and continuity of circuits, switches, fuses and contacts with instant readings.

As well as DC current measurement, the Fluke 325 can handle resistance measurement up to 40 kOhms. It also features all the benefits of the other clamps in the Fluke 320 range, including a back light for use in low light conditions, data hold so you don't lose your reading and true RMS current measurements so you can be confident of accurate readings even on noisy circuits.
