A Micrometer is a widely used instrument for measurement of blocks, depths of slots and outer and inner diameters of shafts precisely. These instruments are very user friendly and well known to provide consistent readings. The precision of a micrometer is achieved by a using a fine pitch screw mechanism.

Types of Micrometer External Micrometer: The instrument is used to measure spheres, shafts, wires and blocks. Internal Micrometer: The instrument is used to measure opening of holes. Depth Micrometer: The instrument is used to measure depths of slots and steps.

These instruments are available in screw form with gauge and used in physics laboratory for accurate and precise readings.
