The grounding resistance soil resistivity tester, also known as the four-wire grounding resistance tester or soil resistivity tester, is a common instrument for testing and measuring grounding resistance. It features a super large LCD gray-white screen backlight display and microprocessor technology, utilizing microprocessor-controlled 2-wire, 3-wire, and 4-wire methods for grounding resistance testing and soil resistivity testing.
This instrument gathers multiple grounding test functions and can quickly and comprehensively measure various parameters in grounding networks. As a new generation of grounding measurement instrument that replaces traditional measurement methods, it is widely used in telecommunications, power systems, meteorology, machine rooms, oil fields, power distribution lines, tower transmission lines, gas stations, factory grounding grids, lightning rods, and more. The instrument is characterized by accurate, fast, simple, stable, and reliable testing performance.
