Beschreibung
Micrometer accuracy comparability The technical difficulty of the three-jaw inside diameter micrometer lies in the hole between the measuring jaws The bigger the space between the measuring jaws, the bigger the dimension error ~~~~~~~~~~~~ 1 Full contact measurement at the measuring floor and 0-mark alignment 2 3/1 measuring surface contact size deviation 0 Shanghai Hengliang brand, small hole between measuring jaws and small size error ~~~~~~~~~~~ 1 Full contact measurement on the measuring surface, 0 mark alignment 2 3/1 measuring surface touch size deviation 0 Differential roller flower design, completely satisfied to rotate Ratchet drive measuring system guarantees accuracy The high-precision screw rod measures the exact inside hole, and the measuring surface is inlaid with carbide, which is wear-resistant and durable 6-12 specifications are for parallax-free readings, and parallax-free readings are extra accurate
