Characteristics in the rating
Sometimes, when measuring precise dimensions, the capabilities of a conventional caliper are not sufficient. At such times, micrometers come to the rescue. These are special devices that can measure with much greater accuracy, up to several microns. Micrometers, despite their minimal measurement error, are not too expensive. Therefore, they should be in the workshop of every self-respecting person who wants to achieve the utmost accuracy when working.
We have compiled a ranking of the top ten mechanical and electronic smooth micrometers. When selecting models, we focused on their capabilities, cost, convenience, and customer reviews that have already used the devices. All you have to do is choose the most suitable option from the ones shown in the rating.
The best mechanical micrometers
Micrometers that don’t need batteries or a screen to display their readings. They have a ruler on the stem with a step size of half a millimeter, and on the drum – a Vernier scale that allows you to determine hundredths of a millimeter. You can use this scale to determine the diameter or width of the part that has been measured. However, you will have to figure out how this works, and read the readings yourself each time.
