225-250 9-10" IP65 Digital Outside Micrometer - 3101 Series (Insize)

The 225-250 9-10" IP65 Digital Outside Micrometer (3101 Series) is a rugged, IP65-rated digital micrometer designed for fast, precise outside measurements in challenging shop environments. Its carbide measuring faces and built-in ratchet deliver repeatable readings even when fluids or coolants are present, helping you maintain tight tolerances without guesswork.

Designed for engineers, machinists, technicians, and hobbyists alike, this micrometer combines effortless metric/inch switching, simple on/off/zero control, ABS/INC measurement modes, and convenient data output. Setting standards are included (except 0-25mm/0-1"), and it ships with a spherical anvil for versatile measurement. Optional data transfer accessories (foot switch for data transfer and data output cable) extend your workflow. When data output is used, measurements can cover up to 300 mm (12") in a single setup.

• IP65 waterproof protection: Keeps measurements reliable in wet, dusty, or coolant-rich environments, reducing downtime and guarding accuracy.
• Carbide measuring faces with ratchet: Durable, wear‑resistant contact provides long tool life and repeatable results across many uses.
• Digital versatility with data output: Easy metric/inch switching, zeroing, ABS/INC modes, and direct data transfer help you capture and record measurements quickly, with a resolution of 0.001 mm / 0.00005" and a measuring range up to 300 mm (12").

Designed to speed up inspection and assembly workflows, this micrometer delivers fast, repeatable readings even in messy environments. The IP65 protection guards against water and dust, the carbide measuring faces resist wear, and the built-in ratchet ensures consistent force. The digital readout and optional data output simplify recording and traceability, so you can build reliable quality records and reduce rework. With included setting standards (except 0-25 mm/0-1"), and optional data-transfer accessories, you can calibrate quickly and capture measurements across the full range up to 300 mm (12").
