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 multiple internal diameters without the need for separate instruments. This model is ideal for machine shops, metrology laboratories, and repair shops.

Features:
- Measuring range: 2-20" (including drum and extension rod combinations)
- Extension rods: 6 extension rods included in the package
- Measuring surfaces: very hard, abrasion-resistant measuring surfaces made of tungsten carbide, suitable for industrial and continuous measurements of hard materials
- Scale: 0.001" analogue reading
- Measuring type: 2-point inside diameter measurement for holes, bushings, tubes, and cylinders.
