Application
● It can measure the roughness of various machined parts, such as
plane surface, bevel surface, outer cylindrical surface, curved
surface, small hole, groove and car axle etc.
● Application for Surface roughness measurement of metal and
non-metal parts and workpiece, including a variety of machining
parts, machining manufacturing, testing, commodity inspection
departments,it is especially suitable for on-site inspection of
large workpiece and production lines and the inspection,
measurement, commodity inspection and other departments of the
outbound verification,no damage to the workpiece.
