Fluke 1625-2 GEO Earth Ground Tester

The Fluke 1625-2 GEO Earth Ground Tester is an advanced, high-performance instrument built to provide precise and efficient earth ground resistance testing in a wide range of environments. It supports all four testing methods — 3-pole, 4-pole, selective testing (using clamps + stakes), and stakeless ground loop measurements (using two clamps) — giving professionals the flexibility to choose the best approach for their testing environment.

One of its key features is Automatic Frequency Control (AFC), which detects electrical interference and automatically selects the optimal test frequency, ensuring highly accurate and stable readings. The tester also offers R* measurement capability, which calculates earth ground impedance at 55 Hz, closely matching the real resistance experienced during fault conditions.

Designed for ease of use, the 1625-2 includes an intuitive rotary selector and function buttons that can be operated even while wearing gloves. It supports USB connectivity for quick data storage and transfer of up to 1500 records, making it ideal for field reporting. With an IP56 rating, the device withstands harsh outdoor conditions, ensuring reliability even in challenging environments.

Whether you’re testing in industrial plants, construction sites, substations, or utility grids, the Fluke 1625-2 combines speed, accuracy, and durability to meet the demands of professional electricians, engineers, and technicians.
