Main Unit for Tubular Inside Micrometer

Mitutoyo 137-014 - Drum for Internal Micrometer (2-2.5")

The Mitutoyo 137-014 is a drum for an internal micrometer and serves as the core of the measuring instrument. Various extension rods can be attached to the drum to significantly extend the measuring range. This micrometer is suitable for measuring a range of internal diameters. These main components are used in combination with Mitutoyo's 137 series extension rods.

Features

- Measuring range (Drum): 2-2.5"
- Resolution: 0.0004" (analog scale)
- Compatible with extension rods from the Mitutoyo 137 series to greatly expand the overall measuring range
- Very hard, wear-resistant measuring surface made of tungsten carbide, suitable for industrial and continuous measurements of hard materials

The design allows for accurate inside diameter measurement of holes, bushings, cylinders, and tubes.
