What are the two kinds of measurement that can be accomplished by the Mitutoyo laser micrometer? The two main types of measurement conducted by the Mitutoyo laser micrometer are diameter measurement and interval measurement. In diameter measurement, the object or part which you need to measure is placed centrally into the laser beam of the micrometer. Then on the central display device, the measurement of the diameter of the part can be read. Alternatively, with interval measurement, two parts or objects can be placed within the laser beam of the micrometer. The readout then provides the distance between the two parts. Furthermore, when using interval measurement, the furthest distance between the two parts can also be measured.
