Product Description

Handheld best valued Clamp Earth Tester 0.01 Accuracy Clamp-on ground resistance tester multi-Functional earth resistance meter
I.Introduction
     Clamp Grounding Resistance Tester is a major breakthrough in traditional grounding resistance measurement. It is widely used in the grounding resistance measurement of the power, telecommunications, meteorology, oilfield, construction and the industrial and electrical equipment. 

     Clamp Grounding Resistance Tester, in the measurement of a grounding system with loop, does not require breaking down the grounding down lead, and no need the auxiliary electrode. It is safe, fast and simple in use.
      clamp grounding resistance meter can measure ground faults which cannot be measured by traditional methods. It can be used in applications where traditional methods cannot be measured, because the HM series clamp grounding resistance meter measures the combined value of grounding body resistance and grounding lead resistance. .
In addition, the C type Clamp Grounding Resistance Tester is also able to measure the leakage current and the neutral current in the grounding system.
