Description

Overview

The Marmonix MEG725 is a clamp-on ground resistance tester that measures earth resistance without the need for auxiliary spikes or disconnecting the ground system. By simply clamping around the grounding conductor, technicians can measure loop resistance from 0.01 ohm up to 1000 ohm and leakage current up to 30 A, making it ideal for testing live or hard-to-access earthing systems. A 55 x 32 mm jaw, 4-digit LCD, 99-group memory and adjustable alarms make it a fast, safe tool for electrical maintenance and safety inspection.
