CA 6472 - Earth & Resistivity Tester: 5 tools in 1 with this tester

This tester guarantees reliable measurements:

  • Through the use of traditional rod methods
  • By self-diagnosis at the start of each measurement which indicates the presence of any faults liable to affect the measurements (poor connections or presence of interfering signals)
  • By extensive measurement ranges: 0.001 W to 100 kW
  • By analysing the frequency behaviour of the earthing systems (from 41 Hz to 5 kHz)

The C.A 6472 is eqipped with high-level, expert calculation capabilities:

  • For earth coupling measurement, it proposes to carry out the 3 measurements necessary and automatically calculates the coupling coefficient
  • For soil resistivity measurement, all you have to do is program the distances used for the measurement and the tester will then calculate r using the Wenner or Schlumberger method.

Other specifications:

  • IP 53 leakproofing
  • Electrical safety: CAT IV 50 V as per IEC 61326-1/ IEC 61010/ IEC 61557-1-4-5
  • Dimensions: 272x250x128 mm
  • Weight 3.2 kg
