Description

The Insize 3127 IP65 digital internal 3 point bore micrometer covers 125–150 mm (4.92–5.91") bores with a precise three-point contact. Built for rugged workshop environments, its IP65 dustproof and waterproof rating protects against dust and splashes, so you can measure confidently in dirty or wet conditions without recalibration or compromised results. Supplied with a manufacturer inspection certificate, this instrument is ready for traceable QA and inspection workflows.

The combination of carbide measuring points for long service life and a bright digital display provides fast, repeatable measurements. Features include automatic power off to conserve battery, a ratchet stop to ensure consistent torque, and easy data transmission, with mm/inch switching and a dedicated data output for logging and record-keeping.

  • IP65 protection for dust and water: Designed to withstand dusty shop air and washdown environments, keeping accuracy intact and reducing downtime.
  • Digital readout with carbide measuring points: 0.001 mm / 0.00005" resolution and 6 µm accuracy with wear‑resistant carbide tips for long‑life measurements.
  • Quick, repeatable measurements with data logging: Ratchet stop, mm/inch, on/off, set controls plus data output for easy logging and error‑free QA records.

For buyers and engineers, this bore micrometer delivers fast, accurate bore measurements with repeatable results, reducing inspection time and improving confidence in part dimensions. The IP65 rating keeps working in challenging environments, while the carbide tips resist wear for longer service life. With automatic power-off, data output, and a certificate of inspection, you’ll have reliable measurements that integrate smoothly into your quality control processes and documentation workflows.
