Tubular Inside Micrometer Carbide Tipped

The 137 series models provide an accurate and flexible solution for measuring inside diameters when the measurement range varies. The extension rod-based measuring system allows the same micrometer for a wide range of internal diameters without the need for separate instruments. This model is practical for use in machine shops, measuring laboratories, and workshops.

Features:

- Measuring range: 50-300mm (Drum and extension rod combinations supplied)
- Extension rods: 13mm, 25mm, 50mm (2 pcs) and 100mm extension rods included
- Measuring faces: very hard, wear-resistant measuring faces 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
