Amprobe GP-2A Ground Resistance Tester
Overview
Poor grounding is a safety hazard and a common cause of equipment failure and downtime. The Amprobe GP-2A provides accurate measurements of both earth ground resistance and soil resistivity for installation and troubleshooting of grounding systems.
The tester automatically checks for noise voltage to prevent false readings and applies three test frequencies for the most accurate result. Measurements can be stored in 999 memory locations and downloaded to a PC with the supplied software to create reports.
