It is critical for facilities to have grounded electrical systems, so that in the event of a lightning strike or utility overvoltage, current will find a safe path to earth. To ensure a reliable connection to earth, the International Electrical Testing Association specifies ground electrode testing every three years.
Fluke's family of earth ground testers have been built to address the entire spectrum of ground testing methods from the basic to the most advanced. Our testers have been designed to be accurate, safe and easy to use. We provide quick and precise resistance measurements through several test methods: 3- and 4-pole Fall-of-Potential testing, selective testing, stakeless testing and 2-pole testing. Detailed application information can be found at the Earth Ground Solution Center.
The Fluke 1623-2 Earth Ground Tester offers all 4 primary test methods: 3- and 4-pole Fall of Potential earth resistance loop testing, 4-pole Soil Resistivity testing, selective earth ground rod testing, and stakeless earth ground rod testing
The Fluke 1625-2 Earth Ground Tester offers all 4 primary test methods, and makes testing even faster with adjustable limits, Automatic Frequency Control (AFC) to minimize existing interference, and higher accuracy 55 Hz R* measurements.
