Description
Overview
GAOTek surface roughness tester is a high-accuracy instrument for measuring surface roughness. It can be used on a variety of machining parts and operates on various surfaces, not only flat but also an outer cone, outer cylinder, curved, pinholes, grooves, recesses grooves and axle, etc. It allows surface roughness measurement both on metal and non-metal workpieces. It is suitable for machining and manufacturing, quality control, and inspection departments, especially for measurement on large and heavy workpieces, assembly lines, and on-site. It is a Non-Destructive Testing instrument; damage won’t cause to the testing piece.
