Tubular Inside Micrometer with Extension

The 140 series models provide an accurate and flexible solution for measuring large internal diameters with a variable measuring range. The extension rod-based measuring system allows the same micrometer to be suitable for various internal dimensions without the need for separate instruments. The model is practical for machine shops, measuring laboratories, and workshops.

Features:

- Measuring range: 40 - 160" (Drum and extension rod combinations supplied)
- Extension rods: 7 extension rods included in the package
- Measuring surfaces: very hard and abrasion-resistant measuring surfaces made of tungsten carbide, suitable for industrial and continuous measurement of hard materials
- Scale: 0.001" analogue reading
- Measuring type: 2-point inside diameter measurement for holes, bushings, tubes, and cylinders
