shock-proof, dust-proof, and moisture-proof structure. It is a commonly used and indispensable
instrument for telecommunications, electric power, meteorology, computer rooms, oil fields,
electronic mechanical installation and maintenance, and industrial enterprises that use
electricity as industrial power or energy. It is suitable for measuring grounding resistance of
various telecommunications, electricity, meteorology, computer rooms, oil fields, power
distribution lines, transmission lines of iron towers, gas stations, factory grounding grids,
lightning rods, etc.
The ground-pile clamp ground resistance tester is controlled by a microprocessor and can
accurately detect ground resistance. It uses fast filtering technology to minimize interference. At
the same time with data storage and data upload functions.
