SR310 Surface Roughness Tester

APPLICATION

Portable Surface Roughness Tester SR310 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 SR310 allows surface roughness measurement both on metal and non-metal workpieces. It is suitable for machining and manufacturing, quality control, inspection departments, especially for measurement on large and heavy workpiece, assembly line, on site. The SR310 is a Non Destructive Testing instrument, damage won’t caused to testing piece.
