1000-3000mm Wide Range Rod Type Inside Micrometer Measuring Device

1000-3000mm Wide Range Rod Type Inside Micrometer Measuring Device
Tubular inside micrometers consist of a measuring head and tubular extension rods. The combination of extension rods provides a wide measuring range, while the tubular design allows for easy insertion into the object being measured. The measuring head delivers precise readings of internal diameters.
Available in ranges from 50-100mm up to 50-1500mm to suit various applications, all our tubular inside micrometers come with protective case packaging.
Key Features
  • Graduation: 0.01mm (Metric) / 0.001" (Inch).
  • Extension rod combination provides wide measuring range.
  • Extension rod diameter: φ28mm.
  • Accuracy: (7+n+L/50)μm (n=number of rods, L=max measuring length in mm/inches).

Applications
Tubular inside micrometers are precision instruments designed for measuring internal diameters of pipes, tubes, and other cylindrical objects with narrow openings. These reliable tools are essential for quality control in manufacturing, automotive, and construction industries.
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.
