Metravi Pro ERT-1635 Double Clamp Earth Tester

The MetraviERT-1635 Double Clamp Multi-function Earth and Grounding Resistance Tester is specially designed and manufactured for on-site measurement of grounding resistance, soil resistivity, grounding voltage, grounding line leakage current, and AC and DC resistance. Applying digital processing technology, it offers precision 4-wire method, 3-wire method, and simple 2-wire method, selection method, and double-clamp method to measure grounding resistance.

The large caliber clamp design can measure the grounding system using large grounding down lead and can flexibly and accurately measure any grounding resistance value of various complex grounding conditions such as single point and mesh grounding. It is not required to disconnect any parallel grounding pole to do the measurements. Import FFT (Fast Fourier Transform) technology, AFC (Automatic Frequency Control) technology, with unique anti-interference ability and environmental adaptability, high repeated test consistency, ensures high precision, high stability and high reliability for long-term measurements.

Widely used in power, telecommunications, meteorology, oil fields, construction, lightning protection and industrial electrical equipment, such as grounding resistance, soil resistivity, grounding voltage, alternating current, leakage current measurement.
