Determine dry and wet film thickness non-destructively — on steel, on non-ferrous metal and in multi-layer build-ups.
Coating thickness decides corrosion protection, hiding power, shade and cost all at once. Too thin means failure in the field, too thick means material given away on every single part. On ferromagnetic substrates the magnetic induction method applies, on aluminium and other non-ferrous metals the eddy current method; neither destroys the coating and both deliver the value in seconds.
It gets difficult with multi-layer build-ups on non-conductive substrates — coating on plastic, for instance — and when the question is not total thickness but the individual layer. Ultrasonic methods resolve the build-up layer by layer. Wet film, by contrast, is measured directly after application with a comb or wheel: the simplest check there is, and the only one that still allows you to intervene during application.
What matters when choosing
Substrate first: steel, non-ferrous metal, plastic or composite
Total thickness or resolution of the individual layers
Measuring range and required accuracy as laid down in the acceptance agreement
Part geometry — edges, radii and small areas need suitable probes
Statistics to standard, such as means over a defined number of measuring points
Calibration foils and zeroing on the actual substrate

Data sheets, operating manuals and quotations are available on request. We quote prices individually, because configuration, accessories and the scope of calibration decide the figure.
After the purchase
An instrument is only worth something once its readings hold up. Calibration, adjustment, repair and operator training are handled from Aesch — the same contact, the same language.
Corvus, our knowledgeable raven, advises you on BYK-Gardner test and measurement instruments: gloss, colour, film thickness, viscosity, physical testing and more — straight from the technical data sheets.

From requirement to instrument
He asks about the measuring task, substrate and standard — and only then recommends a specific instrument.
