Outside Calipers IMPA 650101-650112 — Hardened Steel Measuring Tools for Ships

Outside calipers in the IMPA 650101–650112 range are essential measuring tools for engine room and deck maintenance aboard cargo ships, container vessels, tankers, and offshore support vessels. They are used to measure the outside diameter of pipes, shafts, and other round workpieces during repair, fitting, and inspection tasks. When a chief engineer or engine room fitter needs to verify a pipe OD or check a worn shaft before ordering a replacement, these calipers provide a quick and reliable reading without the need for complex setup.

Each caliper is made from hardened steel with tempered points, giving the tool the wear resistance and durability required in the harsh marine environment. The hardened and tempered construction allows repeated use on metal workpieces while maintaining accurate measurement. The full series covers 12 individual IMPA codes from 650101 through 650112, with each size and configuration ordered and priced separately to match your vessel's specific requirements.
