The Fluke 1623-2 and 1625-2 GEO Earth Ground Testers are cracking tools for field service, industrial maintenance, and power utilities, offering comprehensive earth ground testing for switchgear, motors, and telecom systems.
They perform 3-/4-pole Fall of Potential, 4-pole soil resistivity, selective (1 clamp), and stakeless (2 clamps) tests, measuring 0.02 Ω to 19.99 kΩ with ±2% accuracy (3-/4-pole). The 1625-2 adds Automatic Frequency Control (AFC) for interference mitigation, R* impedance at 55 Hz, and adjustable limits for faster testing. Stakeless testing eliminates stake placement, ideal for indoor or pylon applications, while selective testing targets specific rods.
Both store 1500 records with USB transfer for analysis. Weighing 1.1 kg (7.6 kg with case), these IP56-rated testers use six AA batteries (>3000 tests) and operate in -10 °C to 50 °C. The intuitive interface features a large LCD, rotary switch, and one-button operation. The kit includes test leads, four stakes, three cable reels, two clamps, batteries, a manual, and a professional carrying case. Backed by a three-year warranty, the Fluke 1623-2 and 1625-2 are reliable, efficient mates for precise earth ground diagnostics in rugged environments.
