A surface profile gauge is an essential tool for measuring the texture or roughness of a surface. This gauge is crucial for assessing the surface preparation required for the successful application of coatings, paints, or other finishes. It measures the height and depth of surface peaks and valleys, providing an accurate profile to ensure that coatings adhere properly and have optimal durability. Surface profile gauges are used extensively in industries such as construction, automotive, manufacturing, and marine coatings.
