This is a professional instrument for measuring grounding resistance of electrical equipment. The
whole instrument is stylish and superior grade in appearance and high stable in
performance. With dust proof and moisture proof structure, it is better suited for 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.
