Product Information
Soil resistivity tester also known as grounding resistance-soil
resistivity tester precision grounding
resistance tester, etc. is a common instrument for inspection and
measurement of grounding
resistance commonly used instruments, the use of a large LCD grey
and white screen backlit
display and microprocessor technology to meet the two, three,
four-wire test resistance and Shi soil
resistivity requirements. Applicable to telecommunications,
electric power, meteorology, engine
room, oil field power distribution lines, tower transmission lines,
petrol stations, factories, grounding
network lightning rods and so on. Instrument testing precision,
fast, simple, stable and reliable
characteristics.
