Mahr Roughness Testers

Mahr roughness testers measure and quantify the surface texture of materials by drawing a stylus across a finished surface to detect vertical and horizontal deviations. Surface roughness is an important quality control measurement and is crucial for predicting how two surfaces in contact with each other will wear or seal. Surface roughness is also important when determining how well a surface will hold lubricants or whether paint will properly bond with a surface.
