The technological advancements of the dial indicator and digital electronics previously discussed ( see caliper advancement) have also been separately incorporated into the micrometer. The dial comparator micrometer is equipped with an indicator that takes the place of the vernier scale typically found on the sleeve and thimble. The indicator facilitates measurement reading speed and accuracy.
The digital micrometer , which has an electronically generated digital display , is now without a line graduated measurement scale. The digital display is easy to read and may be reset to zero from any measuring position. Also, the display can be set to read in either inches or millimeters . Finally , due to the electronic nature of the digital micrometer, data collection and statistical evaluation via computer are possible.
