Buy Used Surface roughness measuring equipment

A surface roughness tester is an instrument used to measure the roughness or texture of a surface. It is commonly used in the manufacturing and quality assurance industries to ensure that the surfaces of components and products have the required accuracy and quality. The gauge typically uses a sensor that is dragged across the surface of the material and measures the roughness of the surface. The measured data is then shown on a display and can be used to analyze and assess the quality of the surface. There are several types of surface roughness gauges, including handheld portable units and stationary gauges for measuring large components. Measurement is usually in micrometers (µm) or Ra values (arithmetic average of profile depth).
