50-100mm/1.97-3.94" IP54 Digital Three Points Internal Bore Micrometer Set - 3127 Series (Insize)

The Insize 3127 IP54 waterproof Digital Internal 3-Point Bore Micrometer Set is built for accurate bore measurements in demanding environments. It’s ideal for technicians, engineers, and workshops that work around machine fluids and coolants, delivering quick, repeatable readings in a compact, robust package. The 50–100 mm (1.97–3.94") bore range is complemented by setting rings and extension rods for flexible setup, with optional data output for streamlined data capture.

• Three‑point internal bore design for repeatable measurements: The three contact points ensure stable, consistent readings across varying bore geometries, reducing measurement errors and speeding up inspection workflows.
• IP54 waterproof build with carbide measuring faces and ratchet stop: Designed to withstand fluids and coolants in harsh environments, while carbide faces resist wear for long-life accuracy and the ratchet stop guarantees consistent torque every time.
• Digital readout with unit control and optional data output: Clear mm/inch display with on/off, set, ABS/INC, and data output capability; powered by SR44/LR44 batteries with auto‑power‑down for reliability and convenience (data cable available as an accessory).

This bore micrometer set simplifies hard-to-reach measurements, helps maintain tight tolerances, and integrates smoothly into quality checks or SPC workflows with its optional data output. With durable construction, included extension rods and setting rings, you can trust it to deliver precise results quickly, every time.
