Mitutoyo Series 137 Tubular Inside Micrometer, 50 to 1500 mm Range, 137-205
Technical overview
Mitutoyo 137-205 is a tubular inside micrometer for checking internal dimensions over a wide 50 to 1500 mm range. The steel rod assembly uses hardened steel measuring faces, spring-mounted cylindrical gage rods and a satin chrome scale for reliable 2-point internal measurement. It is suitable for inspection of bores, large internal spans, fabricated components and machine maintenance work where an inside micrometer or ID micrometer is required.
Key Features
- Extension rod inside micrometer covers wide internal measurement.
- Steel rod assembly with hardened steel measuring faces supports stable contact.
- Spring-mounted cylindrical gage rods are held in protective sleeves.
- Satin chrome thimble and sleeve support clear scale reading.
- Supplied with micrometer head, extension rods, spanner and box.
- Made in Japan.
Applications
- Internal measurement of bores, tubes, cylinders and pipe IDs.
- Maintenance inspection of large mechanical assemblies.
- Machine shop and fabrication dimensional control.
- Quality checks where an extension rod inside micrometer is required.
