The Fuzrr ES3001 portable digital ground resistance tester measures the resistance of the earthing system of electrical equipment and cables with high accuracy and resolution. The devices can be used to measure grounding or ground specific resistance in 2-, 3- and 4-wire measurement mode. The ground resistance measurement range is 0.01Ω ~ 30.00kΩ, the soil resistivity measurement range is 0.00Ωm～9999kΩm, so it is perfect for those who are looking for a reliable and easy-to-use device. The high noise level and the USB interface increase the ease of use of the Fuzrr ES3001 ground resistance tester, which allows you to download up to 500 groups of measured values. Whether it's a larger project or a smaller repair job, the ES3001 is the perfect tool for the job.
