Thickness Measurement

Thickness measurement covers the instruments used to determine how thick a wall, sheet, film or component is — whether the part can be reached from both sides or only one. The discipline splits naturally into ultrasonic wall thickness gauging, which reads remaining wall through a single accessible surface on pipes, tanks and vessels, and contact material thickness gauging, which uses a calibrated feeler frame to check sheet, foil, leather and rubber. Both underpin quality control, corrosion monitoring and dimensional verification, which is why Checkline Europe groups the full range here: ultrasonic and magnetic wall thickness gauges, analogue and digital contact gauges, precision benchtop instruments, and the probes and accessories that support them.

Choosing the right method starts with whether you can access one face or two, and with the accuracy your part demands. To understand the measurement principles and their limits, see the Thickness Measurement Knowledge Base; when you are ready to specify an instrument for a particular task, work through the Thickness Measurement Selection Guide.
