Product Details

1、 Overview:

ES3010E soil resistivity testerThe grounding resistance soil resistivity tester, also known as the four wire grounding resistance tester or soil resistivity tester, is a commonly used instrument for testing and measuring grounding resistance. It adopts a large LCD gray white screen backlight display and microprocessor technology, and is controlled by a microprocessor for 2-wire, 3-wire, and 4-wire grounding resistance testing and soil resistivity testing.

ES3010E soil resistivity testerIt gathers many grounding testing functions, which can quickly and comprehensively measure various parameters in the grounding network. It is a new generation of grounding measuring instrument that replaces traditional shaking table measurement. Widely used in telecommunications, power, meteorology, computer rooms, oil fields, power distribution lines, iron tower transmission lines, gas stations, factory grounding grids, lightning rods, etc. Instruments have the characteristics of precise, fast, simple, stable and reliable testing.
