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 for a wide range of internal diameters without the need for separate instruments. The model is practical for machine shops, measuring laboratories, and workshops.

Features:
- Measuring range: 50-150mm (Drum and extension rod combinations supplied)
- Extension rods: 13mm, 25mm, and 50mm extension rods included
- Measuring surfaces: very hard, abrasion-resistant measuring surfaces made of tungsten carbide, suitable for industrial use and continuous measurement of hard materials
- Scale: 0.01mm analogue reading
- Measurement type: 2-point inside diameter measurement for holes, bushings, tubes, and cylinders
