4105A Grounding Resistance Meter, as a professional instrument for measurement of grounding resistance of electrical equipment, is made by improving the circuit, structure and technology of traditional ground resistance meter. With a beautiful and practical fashion style, this meter will provide more complete function, higher accuracy and more convenient operation.

Thanks to thedust-and-moisture proof structure, this meter is better suited to field operation. It is designed to measure the grounding resistance of grounding systems of a variety of power systems, electrical equipment and lightning protection equipment, and also to measure AC voltage.
