6-8mm 0.24-0.31" IP65 Digital Three Point Internal Bore Micrometer - 3127 Series (Insize)

The Insize 3127 IP65 digital three-point internal bore micrometer is a precision tool designed for fast, accurate inside diameter measurements in 6–8 mm (0.24–0.31 in). Built for engineers, technicians, and shop floor use, it delivers quick, repeatable readings with minimal effort—ideal for quality checks, assembly fitment, and benchmark sizing.

Its rugged, IP65-rated housing protects the sensitive measurement components from dust and water, making it reliable in challenging environments. The tool features steel measuring points for durable wear resistance, a ratchet stop to ensure constant contact pressure, and automatic power-off to extend battery life. With mm/inch conversion, data output, and a factory inspection certificate, it integrates smoothly into professional workflows.

• IP65 dustproof/waterproof construction: keeps critical components protected in dirty, damp environments while maintaining measurement accuracy over time.
• Three-point internal measurement for repeatable accuracy: three contact points evenly-size the bore for stable, repeatable readings with improved concentricity and faster setup.
• Digital convenience with data output and ratchet stop: 0.001 mm (0.00005") resolution, 4 µm accuracy, mm/inch switching, and automatic power-off support efficient reporting and consistent measurements.

This bore micrometer helps you move from measurement to action with confidence: quick, reliable readings that reduce rework, protected performance in tough environments, and seamless data capture for traceability. The combination of precise steel tips, a robust IP65 build, and a documented inspection certificate ensures you can trust results across daily use, maintenance checks, and precision assemblies.
