The ETCR2100 clamp-on ground resistance meter is a major breakthrough in traditional ground resistance measurement technology and is widely used in power, telecommunications, meteorology, oil fields, construction and industrial electrical equipment ground resistance measurement.
When measuring a grounding system with a loop, the ETCR2100 clamp-on ground resistance meter does not need to disconnect the grounding lead or auxiliary grounding electrode. It is safe, fast, easy to use, and can measure ground faults that cannot be measured by traditional methods. It can be used in situations where traditional methods cannot measure.
