About Surface Roughness Measuring Instruments & Testers

Quickly and accurately determine the surface texture or surface roughness of a material. A roughness tester shows the measured roughness depth (Rz) as well as the mean roughness value (Ra) in micrometers or microns (µm).

Surface roughness is a component of surface texture and plays a pivotal role in determining how an object will interact with its environment. Roughness is a good indicator of the potential performance of a mechanical component, since irregularities on the surface may form nucleation sites for cracks or corrosion.
