Lonroy LR310 表面粗さ計 (320µm, 12600μin, 17.5mm)

Application

Surface Roughness Tester LR310 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 LR310 allows surface roughness measurement both on metal and non-metal workpieces. especially for measurement on large and heavy workpiece, assembly line, on site. It is suitable for machining and manufacturing, quality control, inspection departments.

The LR310 is a Non Destructive Testing instrument, damage won’t caused to testing piece.
