Thickness Measurement

• Wall Thickness Measurement when only one side is reachable and you need remaining-wall evidence on pipes, tanks, vessels or hulls, by ultrasonic or magnetic-wall gauging.
• Material Thickness Measurement where both faces are in hand for sheet, film, foil, paper or rubber, from analogue dial gauges through digital models to precision benchtop instruments.

For the dry-film thickness of a paint, powder, plating or anodising layer, where the substrate decides whether a magnetic or eddy-current gauge is valid, continue under Coating Inspection.

Why each route measures what it does — the physics under ultrasonic and contact gauging — is set out in Thickness Measurement.
