• Large matt‑chrome measuring drum with ratchet
• Hardened measuring faces and 0.01 mm resolution

Precision where repeatability matters

The micrometer delivers a clear 0.01 mm reading combined with a 1 mm spindle pitch, which together permit controlled advance and straightforward interpretation of measurement changes. The mechanical graduation and the proven DIN standard ensure that readings are traceable and comparable across routine quality checks. The integrated friction ratchet standardises the contact force, reducing variability caused by different operators and improving result reproducibility in serial inspections.

Comfort and control for repetitive measuring

Designed for frequent use, the instrument’s large matt‑chrome measuring drum offers improved grip and a finer feel when setting the spindle. The spindle diameter of 8 mm provides the necessary stiffness for stable measurement, while the friction ratchet prevents over‑tightening and preserves both the measuring faces and the part under test. The hardened measuring faces maintain long‑term wear resistance, so accuracy is preserved even with intensive daily use.

Compact range for fine mechanical tasks

With a measuring range of 75–100 mm, this tool sits in the micro range, making it suitable for precision work on small to mid‑sized components. That range is particularly useful in toolmaking, precision engineering and parts inspection where reach and stiffness must be balanced. The instrument’s mass and dimensions are optimised so that handling remains comfortable while delivering the necessary reach for many common workshop tasks.

Workshop‑ready and transport‑safe

The micrometer is supplied ready for use and comes in a protective transport case for safe storage and movement between the bench and inspection area. Its analogue, mechanical design avoids electronic dependencies and offers immediate, low‑maintenance operation ideal for harsh shop environments. Conformity with DIN 863 supports integration into existing measurement procedures and fits standard inspection routines.

Built for reliable inspection workflows

Combining robust construction, a clear 0.01 mm scale and a torque‑controlled contact mechanism, this instrument supports tight tolerance checks and repeat measurements with confidence. The instrument’s features reduce measurement uncertainty and contribute to steady production quality — a practical choice where repeatability and low upkeep are priorities. Metav’s selection ensures that workshop needs are met with consistent supply and pragmatic service.
