Surface Roughness Tester employ different measurement methods, including contact methods that use a stylus or needle to trace the surface, and non-contact methods that utilize optical or laser technology to capture surface profile information. These testers provide parameters such as Ra (average roughness), Rz (mean peak-to-valley height), Rq (root mean square roughness), and Rmax (maximum peak-to-valley height), among others, to quantitatively evaluate surface texture. The measured roughness data can be used for quality control, process optimization, surface finish comparisons, and conformity to industry standards. Surface roughness tester, also known as a profilometer or surface roughness gauge, is a device used to measure and quantify the roughness or texture of a surface. It provides numerical values or visual representations of the surface irregularities, allowing for quality control, inspection, and characterization of surfaces.
