SRT-310 Surface Roughness Tester
Main feature:
SRT-310 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 SRT-310 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 SRT-310 is a Non Destructive Testing instrument, damage won’t caused to testing piece.
