Fluke GEO Earth Ground Testers

Ensure proper grounding and eliminate equipment failure

These GEO earth ground testers help lower the risk of electric shock to users and eliminate equipment failure. Units aid in establishing and troubleshooting effective grounding systems, for both equipment and structures, and eliminate instrument errors in electrical devices as well as harmonic distortion issues and power factor problems to keep your systems running and operators safe.

These units perform all four essential earth ground tests including three- and four-pole fall of potential, four-pole soil resistivity, one clamp selective, and two clamp stakeless earth ground tests. In addition, model 1625-2 offers advanced features such as automatic frequency control, R* measurement capability, and adjustable limits for quicker testing.

Both are essential for technicians, electrical contractors, and industrial electricians for gas, telecom, utility, and manufacturing applications.
