INSIZE 3282-50 Disk Micrometer 25-50 mm

INSIZE's 3282-50 analogue disk micrometer covers 25-50 mm to an accuracy of 4 µm, with 5 µm parallelism between its disk-shaped measuring faces, for measuring the root tangent length of gear teeth by spanning several teeth at once. It has a 0.01 mm graduation and a ratchet stop, and INSIZE supplies a setting standard with it for checking the zero setting before use.
