Clamp on Earth Resistance Tester
New generation clamp on earth resistance/ground resistance tester, based on loop resistance principle that provides earth resistance measurements without any auxiliary spike electrodes or unhooking ground earth wire. The unit simply has to be clamped onto the ground wire or strip to obtain earth resistance value with high accuracy. The unit also measures leakage current.
