What is a coating thickness gauge used for?

A coating thickness gauge measures the thickness of a protective or decorative coating, such as paint, powder coat, galvanizing or anodizing, on a metal substrate. It confirms the coating meets a specified minimum or maximum thickness without removing or damaging the coating.

What is the difference between magnetic and eddy current coating thickness measurement?

Magnetic induction measures non-magnetic coatings on ferrous substrates like steel. Eddy current measures non-conductive coatings on non-ferrous substrates like aluminium. Some instruments combine both methods in a single gauge.

Is BTSA an authorized Elektrophysik distributor?

Distributor status for Elektrophysik is being confirmed. We will update this page with an accurate statement once verification is complete.

Which coating thickness gauge should I use for powder-coated steel?

A magnetic induction gauge is typically used for powder coating over a steel substrate, since powder coat is non-magnetic and steel is ferrous.

How is a coating thickness gauge calibrated?

Coating thickness gauges are typically zeroed and verified against certified reference foils or shims of known thickness on the same base material being measured, at intervals set by your quality system.

Can Elektrophysik gauges measure coating thickness on aluminium?

Eddy current gauges are designed for non-ferrous substrates such as aluminium and can measure non-conductive coatings, including anodizing, on that base metal.
