April 24, 2022 by Himanshu Arora The micrometer is also known as the micrometer screw gauge and is used to measure the dimensions particularly linear dimensions of the objects. It is used to measure the outside diameter, thickness, and length of solid objects. Parts of the Micrometer Anvil Spindle Frame Barrel Thimble Rachet Range of micrometer

Analog vs. Digital. In recent years, the digitization of measuring instruments has steadily progressed. For example, finding a hand caliper or micrometer with a digital counter is no longer rare. Whereas practice was once required to accurately read the Vernier scale on a pair of hand calipers, digital hand calipers instantaneously display.

Outside Micrometers Mechanical outside micrometers measure outer dimensions in 1" increments to 0.0001" accuracy and resolution. Electronic Outside Micrometers Electronic outside micrometers measure outer dimensions in 1" increments to 0.0001" accuracy and to 50 millionths (1 micron) resolution.… Micrometer Sets

The main scale reading is 8.5 mm which immediately precedes the position of the thimble on the main scale. Now the least count of the instrument is 0.01 mm and the 22nd division of the thimble is coinciding with the main scale then the reading will be. 8.5 + 22 (0.01)mm = 8.72mm.

255 3 8 Vernier calipers I've used just seem to be a bit flimsier than the average micrometer. It may come down to what you prefer reading but my gut feeling is that I trust the advertised precision and accuracy of a micrometer a little more. Too speculative to put as an answer though. – Air Oct 14, 2016 at 17:05 1

These digital micrometers are easy-to-read and do not require operators to do any math. They provide measurements within an accuracy of 0.0001” or 0.0002”. With a third contact point, these micrometers are self-centering and so eliminate errors when taking two-point measurements off of center. Sets include gauges of different ranges.

The micrometre ( Commonwealth spelling as used by the International Bureau of Weights and Measures; [1] SI symbol: μm) or micrometer ( American spelling ), also commonly known by the non-SI term micron, [2] is a unit of length in the International System of Units (SI) equalling 1 × 10−6 metre (SI standard prefix "micro-" = 10−6 ); that is.

Hence, when you buy a new micrometer, a vernier scale should be one thing you take into account. The vernier is also used in other instruments such as theodolites and sextants. However, people today easily find vernier scale on vernier calipers. Vernier Caliper. The vernier applies both in a linear and circular scale model.
