Internal micrometer by Microtech Metrology — digital readout, IP65 protection

A precision internal micrometer designed for internal diameter measurement of large components and fixtures across machining, toolmaking and quality control applications.

• Digital readout with mm/inch and hold
• IP65 protection for harsh environments
• Calibrated to ISO 17025, certificate included
• Friction ratchet for consistent measuring force

Precise measurement for large components with a wide working range

The instrument covers a measuring range of 125–1,000 mm, making it suitable for larger bores and assemblies where repeatability over long spans is required. The construction focuses on profile stiffness and stable guide geometry to reduce bending and variability during measurement. With an accuracy of ±0.02 mm, the device provides reliable numerical results for workshop and inspection tasks where tolerance chains demand consistent data rather than laboratory micro‑precision. The extended reach reduces the need for multiple specialised gauges while keeping handling manageable.

Clear digital readout and operator aids for fast inspections

Equipped with a digital display offering ON/ABS/SET/HOLD functions and mm/inch switching, the gauge simplifies readout and data recording during batch checks. The display resolution of 0.001 mm permits fine judgement of trends and deviations, while the HOLD function secures difficult readings for documentation. Together with the friction ratchet, the measuring process becomes more reproducible: the ratchet enforces a consistent measuring force, limiting user‑induced scatter and speeding up routine measurements in the shop or at the inspection bench.

Robust design and traceable calibration for production use

Designed for demanding environments, the device meets IP65 ingress protection for reliable performance despite coolant mist or dust exposure. Delivered fully calibrated to ISO 17025, the micrometer includes an official calibration certificate, enabling immediate use in traceable quality management systems and easing audit preparation. The weather‑protected electronics and mechanical safeguards also reduce downtime, which supports continuous production and a predictable inspection workflow.

Modular reach with practical extension options

A modular extension system allows adaptation to a broad variety of bore depths: extensions: 25, 50 (2×), 100, 200, 400 mm are available to match specific component geometries. This modularity reduces inventory by enabling one base instrument to cover multiple size classes, shortening setup time and improving workshop flexibility. The extension options are straightforward to mount and lock, promoting fast changeovers between jobs without compromising measurement stability.
