Reliable, Professional-Grade Testing
Engineered for reliability, the Chauvin Arnoux CA 6471 ensures dependable operation through:
- Self-diagnostic startup, highlighting poor connections or disturbances
- Broad measurement range from 0.001 Ω to 100 kΩ
- Adjustable measurement frequency (41 Hz to 512 Hz) for 3P and 4P testing
- Exceptional noise rejection for precise readings even in noisy environments
Whether you‘re testing a ground rod, an industrial site, or a residential grounding resistance setup, the CA 6471 stands out for its high-performance data integrity.
Advanced Earth and Soil Testing
The CA 6471 goes beyond conventional meters by incorporating sophisticated auto-calculation functions:
- Calculates coupling coefficient after three simple resistance readings (R1, R2, R1-2)
- Computes soil resistivity automatically when rod distances are entered
- Supports high-resolution measurements ideal for highly resistive soils
These expert-level tools make the CA 6471 a top-tier soil resistivity tester, saving time while improving diagnostic precision.
3P, 4P, and Clamp-Based Measurements
The earth resistivity tester supports traditional 3-pole and 4-pole measurements, allowing you to measure earth resistance with high precision. The selective 4P mode lets you test in parallel without disconnecting the earth, a huge time-saver for professionals.
When testing in parallel networks, simply connect two clamp-on ammeters—one for signal injection, the other for current detection. This innovative feature makes the Chauvin Arnoux CA 6471 a standout ground resistance tester in both speed and safety.
Compact and Rugged Design
Housed in a robust enclosure, the CA 6471 is built to endure challenging field environments. With a compact dimensions 272 x 250 x 128 mm, it fits easily into toolkits and workspaces. The tester operates on a rechargeable battery and includes USB connectivity for fast data export using Ground Tester Transfer software.
Also included are colour coded accessories and multilingual manuals for streamlined setup and use.
