Roughness Tester

Roughness meters, also known as surface roughness testers, are instruments used to measure the surface texture or roughness of a material. They work by tracing the surface with a stylus and recording the variations in height to determine the roughness profile. These measurements are crucial in manufacturing and quality control, as surface roughness affects the performance, appearance, and wear of parts. Results are typically given in micrometers (µm) or microinches.
