Usage Precautions
- Always connect the largest extension rod to the micrometer head first, then add other rods in sequence to minimize axis bending.
- Check for variation when the micrometer head is fixed and loosened during measurement.
- Ensure proper bearing position during measurement.
Applications
These precision tubular inside micrometers are ideal for measuring internal diameters of pipes, tubes, and cylindrical objects with narrow openings. Essential for quality control in manufacturing, automotive, and construction industries.
