Skan-A-Matic 749040 is a rugged inspection tool designed to check for defects and measurements on parts with thin walls and tight diameters up to 0.750" (19.05 mm). It is an ultra-precise optical dimensional scanning system that can accurately measure thickness, radius, diameter, and depth. The 749040 uses a powerful CCD linear array, paired with highly accurate optical components, to accurately measure material to tolerances of 0.0002" (0.005 mm). The 749040 is equipped with a high-resolution LCD display, allowing users to view real-time readings on the go. The device is lightweight and compact, making it an excellent choice for applications on the go. The 749040 is an ideal solution for production applications and can easily be used to verify parts such as bearings, stamped and formed parts, fasteners, as well as many other components and mechanisms.
