Fluke 1623-2 GEO Earth Ground Tester Kit

The Fluke 1623-2 GEO Earth Ground Tester Kit offers powerful functionality for performing four types of earth ground testing:

• 3- and 4-pole fall-of-potential testing
• 4-pole soil resistivity testing
• Selective testing using one clamp with stakes
• Stakeless testing using two clamps only

With stakeless measurement technology, you can test ground loop resistance without driving auxiliary stakes, making it ideal for indoor environments, paved areas, and locations where soil access is limited. Simply place two clamps around the earth ground rod, and the tester automatically applies a known voltage, measures the current, and calculates resistance — without interrupting the bonded grounding system.

This significantly reduces setup time and allows testing in hard-to-reach areas like power pylons, substations, and building interiors where traditional methods are impractical.

The Fluke 1623-2 also features automatic range selection, error detection for probe resistance, and built-in indicators for ensuring test accuracy. Its IP56-rated housing offers protection against dust and water, while the rugged carrying case ensures durability in challenging field environments. With internal memory storage for up to 1,500 test records and USB connectivity for fast data transfer, reporting and analysis become seamless.

Designed for professionals in electrical installation, industrial maintenance, and grounding system verification, the Fluke 1623-2 delivers precision, flexibility, and reliability on every test.
