Earth Soil Resistivity Tester Meter AC Voltage Measurement with Frequency 128Hz

Description: Earth Soil Resistivity Tester Meter AC Voltage Measurement with Frequency 128Hz Application Scenarios: This soil resistivity grounding resistance tester (multi-function type) is a common instrument for testing and measuring grounding resistance commonly used instruments, he uses a large LCD gray and white screen backlit display and microprocessor technology, through the microprocessor-controlled 2-wire, 3-wire, 4-wire French grounding resistance test and soil resistivity test. Bringing together many grounding test functions, it can quickly and comprehensively measure various parameters in the grounding network. It is widely used in telecom, electric power, meteorology, machine room, oil field, power distribution line, tower transmission line, gas station, factory grounding network, lightning rod and so on. The instrument is characterized by accurate, fast, simple, stable and reliable testing. 　　Microprocessor control, can accurately detect grounding resistance, soil resistivity, grounding voltage and AC voltage. Its use of fast filtering technology can minimize interference. The same screen displays the resistance value of the auxiliary electrode, which is convenient for judging the measurement error due to environmental factors, and facilitates the more accurate measurement of the real resistance value of grounding, while storing 500 groups of data, and the data can be monitored online through the monitoring software, and the USB data can be uploaded to the PC and has the unique functions of value retention and intelligent alarm prompts. 　　By the host, monitoring software, test line, USB cable, grounding pin composition, with historical data reading, access, save, report, print and other functions.
