Product Introduction

The LD-590 dual clamp digital ground resistance tester is meticulously designed and manufactured for on-site measurements of ground resistance, soil resistivity, ground voltage, leakage current in grounding wires, AC current, and DC resistance, incorporating the latest lightning protection ground resistance detection standards. With a test current of up to 20mA, the LD-590 utilizes new digital processing technology, offering precise measurements using 4-wire, 3-wire, and simple 2-wire methods, as well as selection and dual clamp techniques. Its large aperture current clamp allows for the measurement of grounding systems with large grounding wires. It can accurately measure the ground resistance values of various complex grounding situations, such as single-point and mesh grounding, without the need to disconnect any parallel grounding electrodes during parallel grounding measurements, significantly enhancing measurement convenience. The LD-590 incorporates FFT (Fast Fourier Transform) technology and AFC (Automatic Frequency Control) technology, providing unique anti-interference and environmental adaptability with strong consistency in repeated tests. Widely used in the measurement of ground resistance, soil resistivity, ground voltage, AC current, and leakage current in power, telecommunications, meteorology, oil fields, construction, lightning protection, and industrial electrical equipment.
