Fluke 325 True RMS Clamp Meter Replaces Fluke 321 With 40A Resolution Accuracy

Fluke 325 True RMS Clamp Meter: New Generation Replaces Fluke 321

The Fluke 325 replaces the Fluke 321 as the general purpose clamp meter in the Milano electrical range. The 321 used average responding conversion and had a single 400 A range, so small loads and distorted waveforms were difficult to read reliably.

The new generation applies True RMS conversion, keeping readings accurate on variable frequency drives, LED drivers and switching power supplies, and adds a 40 A range with 0.01 A resolution for small loads. A Type K input and a CAT III 600 V rating extend the meter from simple current checks to panel level maintenance work.

What Changes Against the Legacy Model

Key Features

• True RMS conversion gives correct current readings on VFD, LED and switching loads
• 40 A low range with 0.01 A resolution resolves small loads that a 400 A range cannot separate
• Type K input adds temperature measurement for motor and bearing checks
• CAT III 600 V rating suits distribution panel and machine control work
• Backlit display with min max recording for unattended load checks

Technical Specifications

Typical Applications

• Small load measurement on control circuits and lighting panels
• Motor current checks on inverter driven equipment
• Panel maintenance in commercial and industrial buildings
• Bearing and enclosure temperature screening
