The GP-1 is a rugged,battery operated,earth ground resistance tester that automatically calculates resistivity
The GP-1 is a rugged, battery operated, earth ground resistance tester that automatically calculates resistivity and can download to a PC. 100 memory locations allow storage of two point, three point (fall of potential) and four point resistance/resistivity test results. The GP-1 also functions as a voltmeter up to 600 VAC.
The GP-1 is a complete kit for testing existing earth ground electrodes to equipment manufacturer specifications or as mandated by national code requirements of proper grounding, typically 25 ohms or less. The unit also tests soil resistivity for new ground system designs. Other testing applications include cathodic protection, soil contamination, lightning protection and isolated grounding.
