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. Substrate type, expected film range and accuracy class are the specifications that decide the right model.
