KR310 Surface Roughness Tester Portable Surface Roughness Gauge
APPLICATION
Surface Roughness Tester KR310 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 KR310 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 KR310 is a Non Destructive Testing instrument, damage won’t caused to testing piece.
