What Is Surface Roughness Tester?
A Surface Roughness Tester is a precision instrument used to measure the surface texture and finish of materials. It evaluates microscopic surface irregularities such as peaks and valleys created during machining. The tester measures parameters like Ra, Rz, Rq, and Rt to assess surface quality. It works using a stylus probe that moves across the surface and records vertical variations. These movements are converted into electrical signals and displayed as numerical values or profiles. Surface roughness testing ensures quality, consistency, and compliance with standards. It is widely used in automotive, aerospace, manufacturing, and quality control applications.

How Surface Roughness Tester Work?
A Surface Roughness Tester works by using a stylus probe that moves smoothly across the surface being measured. As the stylus travels over microscopic peaks and valleys on the surface, its vertical movements are detected and converted into electrical signals. These signals are then processed by the instrument’s internal electronics and software to calculate surface roughness parameters such as Ra, Rz, and Rq. The measured values and surface profile are displayed digitally, allowing accurate evaluation of surface finish for quality control and inspection purposes.
