The Fluke 1625-2 GEO Earth Ground Tester is a versatile solution for measuring ground resistance and soil resistivity in industrial and utility environments. It supports multiple test methods, including 3-pole, 4-pole, clamp, and selective testing, with onboard data storage for documentation.
Fluke 1623‑2 Basic GEO Earth Ground Tester Kit is a versatile earth ground tester kit for 3- and 4-pole resistance and soil resistivity measurements, enabling selective and stakeless testing with clamps or stakes. It stores results and transfers data via USB, and includes stakes, cables, clamps, batteries, and a rugged case.
The Fluke 1625-2 KIT is a full-featured ground/earth system tester kit offering all four measurement methods (3-/4-pole fall-of-potential, soil resistivity, selective, and stakeless), storing up to 1,500 records and included in a professional hard-kit format for power-utility, industrial and commissioning applications.
The Fluke 1630-2 FC is a high-performance ground-loop/leakage clamp meter that enables non-intrusive testing of bonded grounding systems — no auxiliary stakes needed — with wireless logging and rugged construction for industrial use.
Ground resistance testing plays a critical role in ensuring that electrical systems are safely and effectively grounded. By measuring the resistance of ground rods, grids, and soil, technicians can identify potential risks, validate installations, and maintain compliance with safety codes.
Our collection of ground testers covers every testing method:
Clamp testers offer fast, non-intrusive testing without disconnecting conductors. This method is ideal for routine inspections, allowing quick checks of existing grounding systems without downtime.
Two-point testers use a siple method for basic continuity and resistance checks. These testers are best suited for straightforward applications where only two connection points are available.
The three-point method is the standard approach for accurate soil and earth resistance testing using auxiliary probes. This method balances ease of setup with reliable accuracy for most field conditions.
Four-point testing is the most precise method for soil resistivity studies and site planning for new grounding installations. By separating current and potential leads, 4-point testing minimizes interference and provides the highest accuracy.
