Optical Comparator

Usages:
This instrument is a precision measuring device integrating optics, mechanics, electricity and computation into an organic whole; which is widely used in the labs, college RD, measuring rooms and workshops of related factories and plants in the sectors such as metal mould, clock and watches and electronics industries. This instrument can easily and speedily check the profiles and surface shapes of various measured jobs; e.g., various parts, cutting tools, punching pieces, cams, gears, molding milling cutters, tapping tools, etc.
