Surface Roughness Tester
A portable surface roughness tester is a specialized instrument used to measure and quantify the roughness of a surface. It provides numerical values and graphical representations of the texture and irregularities present on a surface. The tester typically uses a stylus or probe to scan the surface and collect data, which is then analyzed to determine parameters such as Ra (average roughness), Rz (mean peak-to-valley height), and other surface roughness parameters. Surface Roughness Testers are commonly used in industries such as manufacturing, automotive, aerospace, and engineering to ensure the quality and functionality of surfaces.
