Description
The Insize 3127 IP65 digital three-point internal bore micrometer measures inside bores from 25 to 30 mm (0.98 to 1.18 in) with high accuracy. Its three carbide measuring points deliver quick, repeatable readings, while the bright digital display makes interpretation easy in tight spaces. The IP65 enclosure protects against dust and water, so you can rely on it in demanding workshop environments.
Designed for engineers, machinists, quality inspectors, and maintenance professionals, this bore micrometer combines everyday usability with professional-grade precision. It features a ratchet stop for consistent measuring force, automatic power-off to conserve battery life, and convenient data output options for integrating readings into QC records. A manufacturer inspection certificate is supplied for traceability.
- Three-point carbide measuring system: Delivers stable, repeatable bore measurements across the 25–30 mm range with reduced contact wear and improved consistency between readings.
- IP65 protection with digital readout: Dustproof and waterproof reliability in tough environments, with easy mm/inch switching and data transmission for seamless documentation.
- Ratchet stop and automatic power-off: Ensures consistent pressure for repeatable results while automatically saving battery life between measurements.
With a resolution of 0.001 mm (0.00005 in) and an accuracy of 4 µm, the 3127 delivers precise bore checks suitable for tight tolerances, calibration tasks, and quality control workflows. Its included inspection certificate supports traceability, helping you maintain rigorous measurement records across your projects.
