MODEL: Earth Resistance Tester SRT2000+  CE

1. Brief Introduction
SRT2000+ Earth Resistance Tester is widely used in the grounding resistance measurement of the power, telecommunications,    meteorology, oilfield, construction and the industrial and electrical equipment.
SRT2000+ Earth Resistance Tester, in the measurement of a grounding system with loop current, does not require breaking down the grounding wire, and need no auxiliary electrode. It is safe, fast and simple in use.
SRT2000+ Earth Resistance Tester can measure out the faults beyond the reach of the traditional methods, and can be applied in the occasions not in the range of the traditional methods.
SRT2000+ Earth Resistance Tester can measure the integrated value of the grounding body resistance and the grounding lead resistance.
