Surface treatments can be paints, plastics, metals as well as insulating materials.In order to ensure that the extent of application will adequately protect the underlying material from corrosion or abrasion, a certain thickness is required, which varies according to the material being applied.This is where measuring devices for testing the thickness of the layer come into play using the surface measurement technique, which reliably measures the thickness of the coating.The company ElektroPhysik offers accurate professional layer gauges, thickness gauges and probes for measuring layers.
