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 for Using an Inside Micrometer

• Attention must be paid to the temperature during measurement, and avoid excessive measurement time and large-area contact with the inside micrometer by hand during the measurement process. Especially when measuring large dimensions.
• Since the 3-point inside micrometer does not have a force-measuring device, it is necessary to master the force-measuring size. Just touch the surface to be measured to avoid damage to the micrometer or causing large errors due to excessive rotational force.
• When measuring the pore diameter with a 3 point inside micrometer, the surface to be measured must be wiped clean and each section must be carried out in at least two directions perpendicular to each other, and the number of sections should be appropriately increased for deep holes.
• In order to improve the measurement accuracy, the use of the correction value of the inside micrometer should be considered.
• For correct reading, you must face up to the measuring tool reading device, and you cannot squint.
  The internal micrometer avoids high temperatures and direct sunlight radiation and should be maintained frequently.
