Background

A measurement tool is a tool that measures a property. Including length, temperature, time, mass, force, current, voltage, resistance, sound, radio, refractive index and average dispersion, some mechanical measuring tools, such as angle rulers, calipers, etc., were used first in machine manufacturing. In the 16 th century, smooth gauges have begun to be used in artillery manufacture. In 1772 and 1805, a watt micrometer and a length measuring machine for calibration, which measure the length by using the principle of a thread pair, were manufactured in sequence from J.Watt and H.Motzley in UK. After the middle of the 19 th century, measuring tools similar to modern mechanical outside micrometer and vernier caliper appeared successively. At the end of the 19 th century, a complete set of dipsticks appeared. Following the appearance of mechanical measurement tools is a collection of optical measurement tools. At the end of the 19 th century, vertical length gauges appeared, and at the beginning of the 20 th century, length gauges appeared. By the 20 s, measurements have been made in machine manufacturing using projectors, tool microscopes, optical micrometers, and the like.
