Compact precision for small components

Designed for fine workshop and inspection tasks, this digital micrometer delivers a 0–25 mm range that places it within the micro category of measuring tools — the ideal choice where compact dimensions and maximum precision matter. The 0.001 mm display resolution ensures that small deviations are visible at a glance, while the stated accuracy of 0.004 mm provides a realistic expectation of measurement repeatability for typical metalworking and precision assembly checks. This balance of resolution and accuracy makes the instrument suitable for small parts inspection, gauge checks and fine mechanical assemblies where space is limited but tolerance demands remain high.

Consistent handling and reproducible contact

Repeatability is supported by the integrated ratchet spindle, which limits applied measuring force and reduces variation caused by operator technique. The spindle pitch of 0.5 mm and a robust measuring spindle (6.5 mm nominal) maintain mechanical stiffness during contact; the ratchet stop promotes uniform pressure on the workpiece and reduces overshoot. For practical workshop use, the ball‑ended measuring faces allow reliable contact on slightly rounded or turned surfaces, improving centring on shafts and fillets and preventing local indentation on soft materials.

Digital features that streamline inspection workflows

The instrument includes a clear digital display with ON/OFF, ABS/INC, UNIT and SET functions for flexible operation and unit switching. Data transfer is provided via RB 4.1 output, enabling straightforward capture of measured values into data collectors or inspection software for traceable records and batch documentation. These features support rational, process‑driven inspection routines: measurements are taken quickly, recorded without manual transcription and integrated into quality logs to reduce errors and speed decision making.

Durable finish and practical delivery for the workshop

The frame is finished in a lacquered coating while the measuring drum is matt‑chrome, combining corrosion resistance with a non‑reflective surface that aids precise reading and handling. The tool is supplied in a protective transport case to safeguard calibration and mechanical alignment during storage and transit. Such packaging reduces the risk of impact damage when the micrometer is moved between the bench and inspection area, helping to preserve long‑term measurement reliability.
