275-300mm 10.83-11.81" IP65 Digital Three Point Internal Bore Micrometer - 3127 Series (Insize)

The Insize 3127 IP65 Digital Three-Point Internal Bore Micrometer covers a 275–300 mm (10.83–11.81 in) bore range and brings digital precision to inside‑diameter measurements. Designed for engineers, machinists, quality inspectors, and maintenance technicians, it provides fast, repeatable readings with three carbide‑tipped measuring points. Built for the real world, this tool combines rugged IP65 protection with a compact, easy‑to‑use interface and automatic power off to extend battery life. It also includes a manufacturer inspection certificate for traceability.

• IP65 dustproof and waterproof protection: Built to withstand dusty, damp, and wash‑down environments so you can rely on accurate bore readings in busy workshops without downtime.
• Carbide-tipped, three‑point bore measurement: Three contact points deliver stable, repeatable readings across the bore while the durable carbide tips resist wear on hard materials, improving tool life.
• Digital readout with data transmission, mm/inch switch, and ratchet stop: Quick, unit‑free readings plus easy data transfer; switch units on the fly and use the ratchet stop for consistent pressure and repeatable results, with automatic power‑off to save battery life.

Ideal for quick inspection in manufacturing and maintenance workflows, this bore micrometer enables faster setup, traceable results with its inspection certificate, and reliable performance in demanding environments. Its 275–300 mm range covers a wide array of internal diameters, while the combination of three‑point contact and carbide tips supports long‑term accuracy and durability. Optional accessories let you tailor the instrument to your exact process needs, ensuring you can tighten tolerances with confidence.
