Earth resistance tester is also called grounding resistance tester.It is an advanced grounding resistance tester with a variety of measurement methods.Using the large size HD segment code LCD screen display and microprocessor technology, through the microprocessor control precision 4-line method, 3-line method and simple 2-line method to measure the grounding resistance test. Widely used in telecommunications, electric power, meteorology, computer room, oil field, power distribution line, tower transmission line, gas station, factory grounding grid, lightning rod, etc. The instrument has the characteristics of accurate, fast, simple, stable and reliable test. Earth resistance tester Controlled by a microprocessor, it can accurately detect ground resistance, soil resistivity, ground voltage, DC voltage. It uses fast filtering technology to reduce interference to a minimum. The resistance value of the auxiliary electrode is displayed on the same screen, which is convenient to judge the measurement error caused by environmental factors, and is convenient to measure the ground real resistance more accurately. 500 groups of data are stored at the same time, and the mobile phone APP is connected through Bluetooth, or the PC is connected through USB to realize wireless or wired remote measurement, reading historical data, exporting report analysis and other functions. It has unique functions such as numerical retention and intelligent alarm prompt。 Earth resistance tester It consists of host computer, upper computer software, mobile phone APP software, test cable, USB cable, charger and ground pin.
