Product Description

Product Description

ES3020 series clamp ground resistance tester is a new generation of groundless pile measurement method that our company's technical team meticulously developed. It uses a brand new generation of LCD, black screen backlight display and microprocessor technology to measure the grounding resistance through inductive method. Ω+A same screen display.When measuring a grounded system with a loop, it is not necessary to disconnect the ground lead wire, and no need for auxiliary electrodes. It is safe and fast. Widely used in telecommunications, electricity, meteorology, computer rooms, oil fields, power distribution lines, iron tower transmission lines, gas stations, factory grounding networks, lightning rods and so on. The instrument has the test precision, fast, simple, stable, reliable and other features ES3020 series clamp ground resistance tester is microprocessor controlled, can accurately detects ground resistance and leakage current. It uses a fast filtering technique to minimize interference. At the same time store 500 groups of data, online monitoring data through monitoring software, USB data uploaded to PC ,and has unique features such as value retention and intelligent alarm prompting ES3020 series clamp ground resistance tester consists of host computer, monitoring software, test line, USB cable, and grounding pin. It has the functions of reading, viewing, saving, reporting and printing of historical data.
