FUZRR ES3000P Multifunctional Micro-controller 3-Wire Ground Resistance Tester 0-20Kohms High Precision Earth Resistance Tester

Description:
- Multi functional ground resistance tester, also known as earth resistance tester. It is an advanced grounding resistance tester that integrates multiple measurement methods. Adopting large-sized high-definition segment code LCD screen display and microprocessor technology, the grounding resistance test is measured using the 3-wire method and simple 2-wire method controlled by the microprocessor. Widely used in telecommunications, power, meteorology, computer rooms, oil fields, power distribution lines, iron tower transmission lines, gas stations, factory grounding grids, lightning rods, etc. Instruments have the characteristics of precise, fast, simple, stable and reliable testing.

- The multifunctional ground resistance tester is controlled by a microprocessor and can accurately detect grounding resistance, grounding voltage, and DC voltage. It uses fast filtering technology to minimize interference. Displaying the resistance value of auxiliary electrodes on the same screen facilitates the determination of measurement errors caused by environmental factors and facilitates more accurate measurement of the true grounding resistance value. Simultaneously store 500 sets of data, connect to a mobile app via Bluetooth, or connect to a computer via USB to achieve wireless or wired remote measurement, read historical data, export report analysis, and other functions. It has unique functions such as numerical retention and intelligent alarm prompts.

- The multifunctional ground resistance tester consists of a host computer, upper computer software, mobile APP software, testing cable, USB cable, charger, and grounding pin.
