Fluke 1623-2 GEO Earth Ground Resistance Meter
The Fluke 1623-2 is a professional-grade earth ground resistance tester that performs 3-pole, 4-pole, selective, and stakeless testing quickly and accurately. With its IP56-rated rugged design, USB data storage, and support for both clamp-based and stake-based measurements, it’s an ideal tool for engineers, electricians, and field technicians working in industrial and commercial environments.
Description
The Fluke 1623-2 GEO Earth Ground Resistance Meter offers a versatile and efficient solution for performing comprehensive earth ground testing in various environments. It supports four major test methods: 3-pole, 4-pole, selective testing with clamps, and stakeless testing. The stakeless measurement method enables testing without disconnecting parallel grounds or driving auxiliary stakes, making it especially useful for complex or inaccessible grounding systems such as inside buildings, substations, and power pylons.
This tester features a large, backlit LCD display with an intuitive one-button TURN & START operation for faster workflows. With a rugged IP56-rated housing, it withstands harsh outdoor and industrial conditions, while its internal memory stores up to 1,500 test records accessible via the USB interface for seamless data management and reporting.
The 1623-2 improves accuracy with Automatic Frequency Control (AFC) to minimize electrical interference during measurement and provides advanced earth impedance calculations at 55 Hz for more realistic ground resistance analysis. Its flexible testing capabilities allow technicians to measure grounds in challenging environments safely and effectively.
Built for reliability, ease of use, and portability, the Fluke 1623-2 is ideal for electrical contractors, field service engineers, and utility professionals performing earth ground resistance testing in industrial, commercial, and residential applications.
