Fluke 325 True RMS Clamp Meter
The Fluke 325 True RMS Clamp Meter is a compact troubleshooting tool for commercial and residential electricians who need to verify load current, voltage and circuit continuity. True-RMS technology supports accurate AC measurements on non-linear signals, while the jaw measures AC and DC current up to 400 A and the test leads measure AC and DC voltage to 600 V. A slim body, 30 mm jaw and large backlit display support measurements in tight cable compartments.
Beyond core current and voltage checks, resistance reaches 40 kΩ, frequency covers 5 Hz to 500 Hz, and capacitance and contact temperature extend the available diagnostic functions. Min/Max records important values, while Display Hold retains a selected reading on the screen. With CAT III 600 V and CAT IV 300 V ratings, the meter combines a broad range of front-line electrical measurements in one portable tool.
Key Benefits
- Provides True-RMS AC readings on non-linear signals
