A precision measuring instrument designed to measure the internal dimensions of bores, holes, and other cylindrical
spaces with a high degree of accuracy. Unlike traditional micrometers, which measure external dimensions, this tool
specializes in gauging internal diameters. The digital display provides an easy-to-read measurement, improving
accuracy and reducing the chances of human error.

• Resolution: 0.001mm/0.00005′
• IP65 protection level
• Button: on/off, set, mm/inch, ABS/INC, data output
• Automatic power off
• Data output
• Ratchet stop
• Carbide measuring faces (over 12mm series)
• Extension rod are included
• Setting rings are included (Range < 100mm)

How it works:

• Three-point contact: The micrometer has three measuring
  points that evenly distribute pressure on the inner surface of the hole, ensuring
  accurate and repeatable measurements.
• Digital display: The measured diameter is displayed digitally,
  eliminating the need for manual reading and reducing the possibility of errors.
• Extension rods: These can be used to measure deeper holes.

Applications

• Machining and Metalworking: Used to measure the
  internal diameters of bores and holes in metal components, ensuring that
  they meet the required specifications.
• Quality Control: Essential in inspection processes to
  verify the accuracy of internal dimensions in manufactured parts.
• Engineering: Applied in various engineering tasks where
  precise internal measurements are critical, such as in the design and
  fabrication of mechanical parts.
• Automotive and Aerospace Industries: Used for measuring
  the internal diameters of engine cylinders, bearing races, and other
  critical components that require precise tolerances.
