Applications

The inside micrometer is an instrument for the accurate linear measurement of the diameter, thickness, length and other dimensions of solids. 3 point internal micrometer is mainly used to measure internal dimensions such as the internal diameter of a hole or a tube and is widely used in mechanical engineering, machining and most mechanical industries.

Tips: Inside Micrometer Error

In general, the inside micrometer direct measurement error includes the measurement of force deformation error, temperature error and value error, the reading alignment error, contact error and zero alignment error of the length measuring machine. The main factors affecting the internal micrometer measurement error are the force deformation error and temperature error.
