Coating Thickness:

  • Measurement of coating or plating thickness on the surface of an article is another eddy current application. There are many currently available instruments which can perform this function. Most instruments are self contained and can be used for measurement of nonmagnetic coatings on a ferromagnetic base, or nonconductive coatings on a conductive but nonmagnetic base.

Coating Thickness of both Ferromagnetic and Non Ferromagnetic Substrates:

  1. Paint Thickness
  2. Anodize Thickness
  3. Plating Thickness
  4. Clear Coat Thickness

Accuracy:

Microprobes NAS:
± (0.01 mil + 1%) 0-4 mils
± (0.1 mil + 3%) >4 mils
± (0.5 µm + 1%) 0 - 100 µm
± (2 µm + 3%) > 100 µm
