ETCR2000 Clamp Earth Resistance Tester is a clamp-style instrument for non-contact measurement of grounding/earth resistance, designed for use across power, telecommunications, meteorology, oil fields, construction and industrial electrical equipment. It provides safe, fast measurements without the need for auxiliary ground rods and offers strong anti-interference capability and high accuracy.

Applications

• Measurement of grounding resistance for power distribution networks, telecom sites, meteorological towers, oilfield installations, construction sites and industrial electrical equipment.

Key features

• Applies to all kinds of ground conductors: round bar, flat bar, angle iron.
• Non-contact resistance measurement for safe and rapid testing (no auxiliary ground rod required).
• Double protective insulation for enhanced operator safety.
