Fluke 345 Power Quality Clamp Meter

Product Summary

The Fluke 345 is a high‑performance power quality clamp meter designed for electricians and technicians working on variable‑speed drives, UPS systems, switchboards, and harmonic‑rich electrical environments. Combining a 2000 A AC/DC clamp, advanced power quality analysis, and a large colour display, it’s ideal for diagnosing harmonics, load imbalances, power factor issues, and energy consumption in industrial and commercial installations. Its Hall‑effect sensor and low‑pass filter make it especially effective on noisy loads.
