25-50mm 1-2" Digital Outside Micrometer - 3109 Series (Insize)

The 25-50mm 1-2" Digital Outside Micrometer from Insize 3109 Series is a compact, digital tool designed for fast, precise measurements of external dimensions. It’s ideal for engineers, machinists, technicians, and hobbyists who need reliable readings on small to mid-size parts, with a focus on quick setup and repeatable results. The carbide measuring faces provide long wear life, helping maintain accuracy even with frequent use, while a ratchet thimble enables one-handed operation for faster workflow.

Setting standards are included to help you calibrate accuracy out of the box (except the 0-25mm/0-1" range). The instrument features a spherical anvil for versatile contact, a durable battery system using SR44 or LR44 cells, and a user-friendly interface that supports mm/inch conversion, on/off, set, and ABS/INC modes for precise data capture.

• Carbide measuring faces for wear resistance: Delivers a longer tool life and maintains measurement accuracy across repeated use on a variety of workpieces.
• Ratchet thimble for one-handed, consistent pressure: Provides uniform contact force, reducing measurement variance and speeding up readings in busy environments.
• High‑resolution digital readout with flexible units: Offers precise 0.001 mm / 0.00005" resolution, easy mm/inch switching, and straightforward zero/set controls for quick, dependable measurements.

This digital outside micrometer combines durability, accuracy, and ease of use to support quality work across assembly, inspection, and maintenance tasks. It helps you measure with confidence, minimize rework, and keep projects on schedule.
