Inside Micrometer — digital inside measuring instrument, IP65, Microtech Metrology

An inside micrometer designed for precision internal measurement of large bores and assemblies in heavy fabrication and metrology labs.

• Digital display with 0.001 mm resolution
• Measurement range 125–3000 mm
• Delivered with ISO 17025 calibration certificate
• IP65 protection and friction ratchet

Accurate large‑bore measurement that speeds QC decisions

This instrument brings high-resolution readout and repeatable measurement to large internal diameters: the 0.001 mm display resolution combined with a practical ±0.04 mm accuracy enables confident acceptance or rejection of components without time‑consuming secondary checks. The clear digital display (ON/ABS, SET, HOLD, mm/inch) reduces reading errors and shortens cycle time in inspection routines. For production environments where throughput and traceability matter, the measurable benefit is faster, more reliable quality decisions.

Built for harsh workshop conditions and reproducible handling

A robust enclosure rated IP65 protects the electronics against dust and water jets, making the instrument suitable for machine shops and site measurements. The integrated friction ratchet ensures a consistent measuring force, which reduces operator‑induced variation and improves repeatability on large diameters. These design choices translate into fewer measurement re‑runs and less downtime for recalibration or repair, supporting continuous production with consistent metrology performance.

Traceable calibration and process documentation

Delivered fully calibrated to ISO 17025, the instrument arrives with a calibration certificate that documents measurement uncertainty and traceability to national standards. This simplifies audit preparation and supplier qualification processes, since the calibration status and certificate are ready to file. The certificate supports quality systems and demonstrates that measurement data used for release decisions meets recognised laboratory standards.

Flexible extension system for extended ranges and easy setup

The modular extension set (25, 50, 100, 200, 400 mm lengths in multiple pieces) allows the instrument to cover the full 125–3000 mm span without complex adapters. As a result, inspection teams can adapt quickly to differing bore depths and diameters with a single, calibrated measuring system. Fewer tools are needed, storage and training are simplified, and handling remains practical even for extra‑long measurements.
