Magnetic Induction Process

Magnetic induction test method according to the standards:
ISO 2178:2016-3, ASTM 7091

Functional principle

Contact method: The excitation current generates a low-frequency magnetic field with a strength that corresponds to the distance between the probe and the base material. A measurement coil measures the magnetic field. In the instrument, the obtained measurement signal is converted into the coating thickness values via the characteristic probe output function, i.e., the functional correlation between the probe signal and the coating thickness.

Main fields of application: Non-magnetizable coating materials on magnetizable base material.

  • Electroplated coatings of chrome, zinc, copper or aluminum on steel or iron
  • Paint, enamel, lacquer or plastic coatings on steel or iron
