Tester for all types of earth measurements, including pylon earth measurements (with the CA6474 Tower Tester) - soil resistivity - earth coupling - ground potential - continuity and; resistance

The CA6472 Earth & Resistivity Tester can be used for quick, comprehensive surveys of all earthing configurations, offering all the necessary earth measurement functions in a single instrument.

When used with the CA6474 Tower Tester, it can also perform pylon earth measurements, making it a unique but essential tool for diagnostics and maintenance on pylon networks.

The CA6472 Earth & Resistivity Tester offers the possibility of analysing the frequency behaviour of the earth connections thanks to its extensive measurement frequency range (41 to 5,078 Hz). The use of a high-frequency measurement signal makes it possible to assess the behaviour of an earthing circuit in the presence of lightning.
