What Is a Micrometer? Types, Parts, and How to Use One

The primary difference between a digital micrometer and an analog micrometer is how the measurement data is captured and displayed, though both rely on the exact same high-precision mechanical screw mechanism. While an analog micrometer requires manual interpretation of physical lines on a sleeve and thimble, a digital micrometer uses electronic encoders to calculate the distance and show it instantly on an LCD screen.
