Disk Micrometer
A disk micrometer is a measurement tool used to collect data on different lengths or thicknesses of materials. The disk micrometer is designed with measurement faces in the shape of wide and flat plates that can easily measure tough to reach spaces as well as thinner flat materials like paper, rubber, plastic, or metals. The disk micrometer is commonly used to measure the root tangent length of a gear. Since the flat surface of the disks on a disk micrometer can be designed to extend past the diameter spindle and anvil, these measurement tools are great for unusual or more difficult measurement contexts.
