Micrometers

Micrometers a variety of measuring instruments are used to measure the width, length or thickness of small objects and high resolution requirements. The use of micrometers is divided into 3 types: external micrometer Measure the thickness, width, or diameter of the object. Internal Micrometer Measure the diameter of holes and pipes. Depth gauge micrometer Measuring the depth of the opening.

At present, the micrometer is designed according to the style and usage. But we can split the micrometer into 2 types: digital, easy to use, comfortable to read. And the durable analogy can be used without a battery.
