Company Profile:
Applications
Single Type inside micrometers are precision measuring instruments especially useful for measuring the inside diameter of pipes, tubes, and other cylindrical objects with narrow openings. They are essential for quality control in manufacturing, automotive, and construction industries.
Precautions
- Check whether the zero line is accurate before use
- Clean the measuring surface of the workpiece during measurement
- Wipe the measuring rod and anvil clean before measuring
- Use ratchet device when screwing the movable sleeve
- Do not loosen the back cover to prevent zero line changes
- Do not add ordinary engine oil between fixed and movable sleeves
- After use, clean, oil, and store in fitted case in dry place
