Ground Resistance Meter Vanlison 0.01Ω Resolution

Description

Product Overview

The Vanlison DY5500 is a professional‑grade ground resistance meter designed for accurate electrical testing in industrial environments. It measures ground resistance from 0.01Ω to 2000Ω with 0.01Ω resolution, insulation resistance up to 2000MΩ, and AC/DC voltage up to 1000V. Housed in a rugged ABS case weighing 4.9 lb, the device features a backlit LCD, auto‑illumination, and an auto‑zero function for consistent readings. Powered by eight AA batteries (included), it offers up to 30 hours of continuous operation.

Usage

Ideal for electricians, engineers, and field technicians, the DY5500 excels in power plant grounding checks, construction site safety audits, and routine maintenance of grounding systems. Its non‑intrusive testing allows measurements without disconnecting existing grounding, saving time and reducing downtime.
