Micrometer accuracy comparison
The technical problem of the three-jaw inside diameter micrometer lies in the hole between the measuring jaws The greater the space between the measuring jaws, the larger the dimension error
~~~~~~~~~~~~
1 Full contact size on the measuring surface and 0-mark alignment
2 3/1 measuring surface contact measurement deviation zero
Shanghai Hengliang brand, small gap between measuring jaws and small measurement error
~~~~~~~~~~~
1 Full touch size on the measuring surface, zero mark alignment
2 3/1 measuring floor touch measurement deviation zero
Differential curler flower design, happy to rotate Ratchet drive measuring gadget ensures accuracy
The high-precision screw rod measures the precise internal hole, and the measuring floor is inlaid with carbide, which is wear-resistant and durable
6-12 specs are for parallax-free readings, and parallax-free readings are extra correct
