ETCR2000A+ Clamp Earth Resistance Tester, also known as clamp type earth resistance tester, single clamp earth resistance tester, loop resistance tester, lightning protection earth resistance tester, lightning protection earth resistance tester, which is used for measurement of earth resistance, loop resistance, and grounding fault judgment.
In the loop grounding system measurement, no need to disconnect the grounding down lead, and not request the auxiliary grounding pole, which is safe, fast and convenient to use.the clamp earth resistance tester is widely used in earth resistance and loop resistance measurement of electric power, telecommunications, meteorology, oil fields, construction and industrial electrical equipment.The long clamp is particularly suitable for flat steel grounding site.
