Tubular Inside Micrometer Carbide Tipped

The 137 series models provide an accurate and flexible solution for measuring inside diameters when the available measuring range varies. The extension rod-based measuring system allows the same micrometer to be used for various internal dimensions without the need for separate instruments. The model is practical for machine shops, measuring laboratories, and workshops.

Features:

- Measuring range: 50-1500mm (Drum and extension rod combinations supplied)
- Extension rods: 13mm, 25mm, 50mm (2 pcs), 100mm, 200mm (3 pcs), and 300mm (2 pcs) extension rods included in the package
- Measuring surfaces: Very hard, abrasion-resistant measuring surfaces made of tungsten carbide suitable for industrial and continuous measurement of hard materials.
- Scale: 0.01mm analogue reading
- Measuring type: 2-point inside diameter measurement for holes, bushings, tubes, and cylinders.
