Correct measurement method

A micrometer is a measuring instrument for precise measurement.

How to read graduations

The sleeve reads a measurement of 7.0 mm, and the thimble reads a measurement of 0.37 mm, resulting in a measurement of 7.37 mm.

The sleeve reads a measurement of 7.5 mm, and the thimble reads a measurement of 0.37 mm, resulting in a measurement of 7.87 mm.

Micrometer basics

A micrometer is a measuring instrument that uses the rotation of a precision screw to take precise length measurements.
It is used for more precise measurements than those provided by vernier calipers.

How to hold a micrometer

Hold the heat-resistant cover to suppress the thermal expansion of the micrometer and use the ratchet stop to measure at a constant measuring pressure.

Types of micrometers

In addition to the standard type, various types of micrometers are available depending on the shape and characteristics of the object to be measured, such as inner diameter, step, narrow groove, the inner diameter of a deep hole.

Micrometer stands

Holding a micrometer in a micrometer stand allows measurements in a stable posture.
This posture reduces the effects of parallax and thermal expansion caused by direct hand contact with the micrometer or the object to be measured.
