True RMS measurements and optimized ergonomics make the 320 Series clamp meters the most important measuring instruments for installation and troubleshooting in industrial and building technology applications. The Fluke 323, 324 and 325 clamp meters are used to check circuits, switches, fuses and contacts for the presence of load current, AC voltage or continuity. These compact and robust clamp meters are ideal for current measurements up to 400 A in cramped control cabinets. The Fluke 325 clamp meter also enables DC current and frequency measurements.
