Micrometer What is micrometer? A simple meaning can be thickness measurement, an instrument that measures small distances, angles or objects. A micrometer sometimes known as a micrometer screw gauge, is a device used widely in mechanical engineering and machining as well as most mechanical trades for precision measurement, along with other metrological instruments such as dial calipers and vernier calipers.
Depth micrometerThe depth micrometer is used to measure the precise depth of holes, grooves and recesses by using interchangeable rods to accommodate different depth measurements. When using a micrometer, you must make sure the base of the micrometer has a flat, smooth surface to rest on and that it is held firmly in place to endure an accurate measurement.
