Coating Thickness Gauges
Coating thickness gauges read dry-film thickness directly, using magnetic induction on ferrous substrates and eddy-current on non-ferrous metals — many models switching between the two automatically. The range here spans entry-level paint checkers through to dual-principle instruments with onboard statistics and data output, all measuring to ISO 2808. For layer-by-layer checks, a paint inspection gauge cuts a small, precise groove through the coating so that individual layers and total thickness can be read under magnification. Substrate type, expected film range and accuracy class are the specifications that decide the right model.
