16-20mm 0.63-0.79" IP65 Digital Three Point Internal Bore Micrometer - 3127 Series (Insize)

The Insize 3127 IP65 digital three-point internal bore micrometer is built for fast, accurate checks of 16–20 mm bores. Its rugged, IP65-sealed body is dustproof and waterproof, so you can rely on measurements in dirty or damp environments. With carbide measuring points, a digital readout offering 0.001 mm (0.00005") resolution and 4 µm accuracy, and a ratchet stop, it delivers quick, repeatable results. It also features mm/inch switching, data output, and automatic power-off, and it ships with a manufacturer inspection certificate. Optional accessories are available to tailor it to your workflow.

• IP65 sealed design for dust and water resistance: Keeps measurements accurate and protects the electronics in harsh shop conditions, reducing downtime and maintenance.
• Three-point internal measurement with carbide tips: Delivers fast, stable, and durable bore readings in the 16–20 mm range, with wear-resistant tips that last longer in daily use.
• Digital readout with data output and measurement consistency: Easy-to-read display, mm/inch switching, data transmission, automatic power-off, and a ratchet stop that ensures the same measuring force every time.

This micrometer helps you speed up internal bore verification while improving accuracy and traceability across QA records. The 16–20 mm range covers common components, and carbide tips resist wear for longer service life. The IP65 protection keeps working in dusty or wet environments, while the built-in data output and certificate support efficient reporting and compliance. Choose it for reliable, repeatable measurements that fit smoothly into busy production or workshop workflows.
