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 suitable for various internal diameters without the need for separate instruments. This model is practical for use in machine shops, measuring laboratories, and workshops.

Features:

- Measuring range: 2-6" (Drum and extension rod combinations supplied)
- Extension rods: 3 extension rods included in the package
- Measuring tips: very hard, abrasion-resistant measuring tip made of tungsten carbide, suitable for industrial and continuous measurement of hard materials
- Scale: 0.001" analogue reading
- Measurement type: 2-point inside diameter measurement for holes, bushings, tubes, and cylinders.
