The ES3050 is engineered for precision equipotential bonding tests on metal structures, lightning protection systems, and grounding grids. Its microprocessor-controlled four-wire method ensures accurate measurements of low resistances (e.g., transformer windings, weld points). Includes real-time monitoring software for data analysis and reporting.
