Starrett Outside Micrometers with Analog Counter
A mechanical analog counter displays measurement readings. These micrometers do not require batteries. They have a ratchet-stop thimble with a speeder knob to reduce the time it takes to open and close the micrometer. The thimble has a constant-force mechanism, so that once the spindle contacts the surface of the measured object, it will stop tightening. This ensures repeatable measurements and prevents over-tightening. When the spindle stops tightening, the thimble stops turning, but the speeder knob will continue turning with a clicking sound.

Mitutoyo Outside Micrometers with Analog Counter
Measurement readings are displayed on a mechanical analog counter. These micrometers do not require batteries. They have a friction thimble with a constant-force mechanism, so that once the micrometer’s spindle contacts the surface of the measured object, it will stop tightening. This ensures repeatable measurements and prevents over-tightening. Once the spindle has stopped tightening, the thimble will continue turning with resistance. A speeder knob reduces the time it takes to open and close the micrometer.
