The Insize 3530 Series Digital Point Micrometer covers a 75–100 mm (3–4") range and is tailored for measuring web thickness on drills, small grooves, and keyways. With a crisp digital readout and a resolution of 0.001 mm (0.00005"), it provides fast, repeatable measurements you can trust in shop and inspection environments.
- Wide range with easy unit switching: Measures from 75–100 mm (3–4") and switches between millimeters and inches at the push of a button for versatile use across different parts and standards.
- Durable, wear-resistant design: Carbide measuring faces withstand daily use, while the ratchet stop ensures consistent pressure and repeatable results in busy workshop conditions, all within an IP54-protected housing.
- Powerful, flexible data and setup: Relies on a long-life LR44 battery with automatic power-off and offers data output capability; ships with setting standards (except 0–25 mm) and has an optional data output cable (code7302-SPC6) for SPC workflows.
This digital point micrometer helps you speed up quality checks and reduce downtime by delivering precise web-thickness measurements quickly and reliably. The combination of carbide tips, protective IP54 housing, and a user-friendly control set supports consistent results day after day, while optional data output enables seamless integration into measurement records and report workflows.
