It is critical for facilities to have grounded electrical systems. This is 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 electrical earth ground testers have been built to address the entire spectrum of ground testing, With methods from the basic to the most advanced. Fluke’s earth/ground testers have been designed to be accurate, safe and easy to use.

Fluke provides quick and precise resistance measurements through several test methods: 3- and 4-pole Fall-of-Potential testing, selective measurement testing, stakeless testing and 2-pole testing.
