A micrometer, micron, or micrometer screw gauge is a linear test and measurement tool designed to measure the thickness or distance of extremely miniature materials with a high degree of accuracy. These micrometers display the readings or measurements in both metric and imperial forms. With the “μm” symbol, they come in various types to offer several measurement ranges. Furthermore, micrometers have several parts to measure materials and are more efficient in their precise functions than other tools, such as vernier calipers.
For What Materials Are Micrometers Usually Used?
Typically, they are suitable for measuring the diameter and thickness of very fine and microscopic linear materials. They are also used for measuring materials, such as:
- Papers
- Microscopic Particles
- Plastics
- Tiny Holes, Wires
- Nails and Screws
- Foils, and
- Sheet Metals.
Why Should I Use a Micrometer?
Micrometers provide splendid benefits with high precision measurements of tiny materials. They are portable, easy to operate and offer consistent measurements. The items usually fit between the spindle and anvil of the gauges; are easily measured by having the length, depth, and thickness below one inch.
Choosing the Right Micrometer
It is crucial to ascertain various parameters before considering the right micrometer. Some of the essential factors include:
- The type of micrometer
- The quality of a micrometer
- The application of micrometer
- The accuracy of a micrometer
- The range and resolution
- The adaptability of a micrometer
Popular Types of Micrometers
These measuring devices are classified into three types: outside micrometers, inside micrometers, and depth micrometers. They are further divided into several types based on their respective functions and designs and include:
- Ball Micrometers
- Blade Micrometers
- Bore Micrometers
- Bench Micrometers
- Digital Micrometers
- Limit Micrometers
- Pitch Micrometers
- Point micrometers
- Tube Micrometers
- Universal Micrometers
- Vernier Micrometer
Why and When to Calibrate a Micrometer?
These standard tools need to be calibrated to ensure they function correctly. It is crucial to calibrate the micrometer at regular intervals to get accurate measurements and data. A typical micrometer (one inch) comes with a readout division of 0.001 inches and ±0.0001 inches of accuracy. It is recommended to operate the measurement at room temperature to get this high level of accuracy.
