Surface Roughness Tester
Surface Roughness Tester
OPT-SR Surface Roughness Tester is a high accuracy instrument for measuring surface roughness. it can be used on variety of machining parts and operates on various surfaces, not only flat but also outer cone, outer cylinder, curved, pinholes, grooves, recesses grooves and axle etc.
The OPT-SR allows surface roughness measurement both on metal and non-metal work-pieces. it is suitable for machining and manufacturing, quality control, inspection departments, especially for measurement on large and heavy work -piece, assembly line, on site. The OPT-SR is a Non Destructive Testing instrument, damage won’t caused to testing piece.
