75-100mm Outside Micrometer 0.01mm Graduations in wooden case
75-100mmoutside micrometer 0.01 Graduations, in wooden case is used for measuring the thickness or outside diameter of small parts. They are industry standard measuring tools because of their high accuracy/resolution and ease of use.
This outside micrometer has a ratchet stop and mechanical digit counter. Graduation options of 0.01mm or 0.001mm. Includes standard bar.

Reading of The 75-100mm Outside Micrometer 0.01 Graduations
Cylindrical Parts
- Contact surfaces of cylindrical part and micrometer are cleaned.
- Micrometer is opened slightly larger than cylindrical part.
- Anvil is seated squarely on the surface of the cylindrical part.
- By moving back and forth around the diameter of the cylindrical part, micrometer is closed slowly.
- While closing the micrometer, first contact is felt then rock sideways for finding the position over centre.
- Steps are repeated for 4 to 5 times till the perpendicular position are found.
Flat Parts
- Contact surfaces of flat part and micrometer are cleaned.
- Micrometer is opened slightly larger than flat part.
- Anvil is seated squarely on the surface of the flat part.
- With the use of ratchet, micrometer is closed slowly until ratchet clicks.
- Reading is recorded.
- Entire procedure is repeated for few times and then average readings are calculated.
