Jlab Export is a leading External Micrometer Manufacturer,and suppliers in India
External Micrometer (code EL-CLE-9064) is a set of outside micrometers, one each for 0–25, 25–50, 50–75 and 75–100 mm, for measuring external diameters and thicknesses. Each has a hardened and ground alloy spindle with a locknut, a ratchet or friction thimble and a rust-resistant finish, and the set comes in a fitted case. JLab makes this four-size micrometer set in Ambala, India.

How a Micrometer Reading Is Taken
Turning the thimble screws the spindle towards the fixed anvil until the work is held between them. The sleeve scale counts whole turns of the screw and the divisions round the thimble give the fraction of a turn, so the least count equals the screw pitch divided by the number of thimble divisions. The ratchet or friction thimble slips at a set force, so each reading is taken at the same measuring pressure, and the locknut holds the spindle once the size is found.
Why the Set Has Four Frames
Each micrometer spans 25 mm, so the frames step up in size to cover external sizes from 0 to 100 mm between them; pick the frame whose range contains the part.
