Product Introduction

Multifunctional Ground Resistance Tester, also known as Ground Resistance Tester, is an advanced ground resistance tester that integrates multiple measurement methods. It features a large-size high-definition segment LCD screen and microprocessor technology, controlled by a microprocessor to perform precise 4-wire, 3-wire, and simple 2-wire measurements for ground resistance testing. Widely used in telecommunications, power, meteorology, computer rooms, oil fields, power distribution lines, tower transmission lines, gas stations, factory grounding networks, lightning rods, etc. The instrument is characterized by accurate, fast, simple, stable, and reliable testing.

Multifunctional Ground Resistance Tester is controlled by a microprocessor, capable of accurately detecting ground resistance, soil resistivity, ground voltage, and DC voltage. It uses fast filtering technology to minimize interference. The resistance value of auxiliary electrodes is displayed on the same screen, facilitating the judgment of measurement errors caused by environmental factors and enabling more accurate measurement of the true ground resistance. It can store 500 sets of data, connect to a mobile app via Bluetooth, or connect to a computer via USB for wireless or wired remote measurement, reading historical data, exporting reports for analysis, etc. It also features unique functions such as value hold and intelligent alarm prompts.

Multifunctional Ground Resistance Tester consists of a host, PC software, mobile app software, test leads, USB cable, charger, and grounding rods.
