Product Introduction
ET3100 Multi-functional Clamping Earth Resistance Tester
The double clamp multi-function ground resistance tester is combined with the new lightning protection ground resistance detection standard, and is specially designed and manufactured for on-site measurement of ground resistance, soil resistivity, ground voltage, ground wire leakage current, AC, and DC resistance. Test current up to 20mA. Using the latest digital processing technology, precision 4-wire method, 3-wire method and simple 2-wire method, selection method, double clamp method to measure ground resistance, Large-caliber current clamp design, can measure the grounding system using large grounding down conductors, and can flexibly and accurately measure any grounding resistance value of various complex grounding situations such as single-point and mesh grounding, and there is no need to disconnect any parallel grounding when parallel grounding measurement Electrode to maximize the convenience of measurement.
