Chauvin Arnoux CA6416 Earth Clamp

The Chauvin Arnoux CA6416 Earth Clamp is a highly capable testing instrument designed for precise measurement of loop resistance, loop inductance, and leakage current. Its robust clamp is resistant to interference, ensuring accurate readings even in challenging conditions. This device is particularly useful for those working in environments where driving stakes for ground testing isn’t practical, making it an ideal solution for installations in urban areas, telecommunication setups, and subterranean or surface pipelines.

This earth tester measures loop resistance from 0.01Ω to 1500Ω, loop inductance from 10µH to 500µH, and leakage current from 0.2mA to 40A. Additionally, the meter is equipped with a user-adjustable alarm for ground voltage, providing added safety. The OLED display offers a clear view from all angles, displaying resistance, ground voltage, and inductance readings simultaneously for more efficient data gathering. Its ergonomic design, including an assisted trigger and silicone dial, makes it comfortable to operate in demanding conditions, even when wearing gloves.

Built for Precision and Convenience

The Chauvin Arnoux CA6416 stores up to 300 readings in its memory, allowing users to recall and track their measurements easily. The pre-hold function holds the reading as soon as the clamp jaws open, ensuring accurate data capture. This feature proves especially useful when taking measurements in hard-to-reach areas. Prioritising safety, the device meets the highest electrical standards with its CAT IV 600V rating.

Powered by four AA batteries, the Chauvin Arnoux CA6416 provides long-lasting performance, offering up to 1440 measurements per charge. Whether you’re working in a rural setting or within a high-voltage installation, this earth clamp delivers consistent, reliable results across a range of ground-testing applications.
