Tubular Inside Micrometer with Extension

The 140 series models provide an accurate and flexible solution for measuring large internal diameters where the available measuring range varies. The measuring system based on extension arms allows the same micrometer to be applied for a wide range of internal diameters without the need for separate instruments. This model is practical for machine shops, measurement laboratories, and repair shops.

Features:

- Measuring range: 1000-4000mm (Drum and included extension arm combinations)
- Extension arms: 50mm, 100mm (2 pieces), 200mm, 500mm, and 1000mm (2 pieces) extension arms included in the package
- Measuring surfaces: Very hard, abrasion-resistant measuring surfaces made of tungsten carbide suitable for industrial measurement of hard materials.
- Scale: 0.01mm analogue reading
- Measuring type: 2-point inside diameter measurement for holes, bushings, tubes, and cylinders.
