Sturdy Flukes. Reliable Flukes. Flukes are accurate.



True-rms measurements and optimized ergonomics make the 320 Series Clamp Meters the best general troubleshooting tool for commercial and residential electricians. The 323, 324 and 325 series are designed to check for the presence of load current, AC voltage and continuity of circuits, switches, fuses and contacts. These small, sturdy clamp gauges are ideally suited for current measurements up to 400 A in tight cable enclosures. The Fluke 325 also offers DC current and frequency measurements.

The Fluke 1550C performs digital insulation testing up to 5 kV, and makes data collection easy through the Fluke Connect™ wireless app. Remote operation lets you spend as little time as possible in potentially hazardous zones. Real-time trending shows a live graph on your phone, rather than a hard-to-read set of changing values. And you can create reports quickly, using pre-designed templates that you can customize with company logos. It’s the perfect tool for preventive or predictive maintenance programs designed to identify potential equipment failures before they occur. And it comes with a three-year warranty and CAT IV 600 V safety rating.
