Precision where internal diameters matter

The three‑point contact geometry gives a stable and repeatable measuring interface, turning small positional changes into consistent results. With a nominal measurement range of 80–90 mm and an indicated accuracy of ±0.006 mm, the instrument is suited to tasks that require fine repeatability rather than long‑range inspection. The analogue design combines mechanical robustness with an easily readable scale, offering straightforward checks without reliance on batteries or electronics. The internal spindle and contact assembly centre automatically in the bore, which reduces routine setup time and improves throughput in serial checking.

Built for repeatable workshop use

A self‑centring contact system minimises operator‑induced misalignment, translating into fewer scrap parts and faster quality confirmation. The micrometer’s contact faces are provided for reliable contact behaviour under repeated use, maintaining measurement integrity across production shifts. Because the instrument is analogue and mechanically driven, maintenance is limited to periodic cleaning and light lubrication; this reduces downtime compared with electronic alternatives while keeping long‑term operating costs predictable. The compact geometry also permits access to relatively small bores where conventional large gauges would be cumbersome.

Practical handling and transport

Handling benefits from the instrument’s compact build and the three‑point principle: the contact points stabilise the tool during insertion and measurement, which is advantageous when inspecting blind or off‑centre bores. Delivery includes a protective transport case to safeguard the instrument during storage and transit, supporting reliable calibration intervals and preserving the measuring faces. Clear markings and a mechanical adjustment allow experienced technicians to integrate the gauge quickly into existing inspection routines or use it as a reference tool for in‑process checks.
