Starrett Electronic Outside Micrometers with Calibration Certificate

These micrometers come with a calibration certificate traceable to NIST that states they've passed a test for accuracy. All have a friction thimble with a constant-force mechanism, which stops the spindle from tightening once it contacts the surface of the measured object. This ensures repeatable measurements and prevents over-tightening. Once the spindle has stopped tightening, the thimble will continue turning with resistance.
Zero-position memory, also known as absolute (ABS) positioning, retains the measuring position when the micrometer is turned off. A zero-set button allows you to start measuring at any point.

Harsh Environment Starrett Electronic Outside Micrometers with Calibration Certificate


These micrometers come with a calibration certificate traceable to NIST that states they've passed a test for accuracy. All are IP67 rated for protection from dust and temporary water submersion. Zero-position memory, also known as absolute (ABS) positioning, retains the measuring position when the micrometer is turned off. A zero-set button allows you to start measuring at any point.
Each micrometer has a thimble with 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.
Friction thimbles continue to turn with resistance when the micrometer’s spindle stops tightening.
Ratchet-stop thimbles have a speeder knob to reduce the time it takes to open and close the micrometer. When the spindle stops tightening, the thimble stops turning, but the speeder knob will continue turning with a clicking sound.

Tip Sets for Outside Micrometers





Turn your micrometer into a specialty micrometer capable of measuring slots, grooves, angles, cylindrical walls, and other surfaces. The ball-shaped tip comes with two balls. If one ball gets damaged or worn, replace it with the other one.
Use ball-shaped tips to measure the wall thickness of pipe, tubing, and other curved surfaces.
Use blade-, cone-, knife-, and spline-shaped tips to measure grooves, slots, and other hard-to-reach dimensions.
Use disc-shaped tips to fit into recesses to measure the thickness of gear teeth.
