Outside Micrometers for Gears with Calibration Certificate
These micrometers come with a calibration certificate traceable to NIST that states they've passed a test for accuracy. The disc-shaped anvil and spindle fit into narrow recesses to measure the thickness of gear teeth. Each micrometer has a ratchet-stop thimble with a speeder knob to reduce the time it takes to open and close the micrometer. A constant-force mechanism stops the micrometer’s spindle from tightening once it contacts the surface of the measured object. 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.
223-125 model has a mechanical analog counter that displays measurement readings. It does not require batteries.
323-350-30 model displays measurements on an easy-to-read LCD. It has zero-position memory, also known as absolute (ABS) positioning, which retains the measuring position when the micrometer is turned off. A zero-set button allows you to start measuring at any point.
