Three‑point internal micrometer M312.132 — 10–12 mm, adjustable setting ring (Metav IndustryLine)

The Three‑point internal micrometer M312.132 is a precision instrument for measuring internal diameters from 10 to 12 mm, featuring an adjustable setting ring and a matt‑chrome scale for clear, low‑glare readings.

• Three‑point internal measurement
• Measuring range 10–12 mm
• Accuracy ±0.004 mm
• Carbide measuring faces
• Adjustable setting ring

Precision for fine internal diameters

The instrument delivers high repeatability for small bores by using a three‑point measuring head that centres automatically in the workpiece. With a measuring range of 10–12 mm and an indicated accuracy of ±0.004 mm, this micrometer is classified in the micro group for extremely compact, fine‑mechanical tasks. The vernier scale is matt‑chrome plated to reduce reflections and to provide clear, long‑lasting legibility under workshop lighting.

Designed for blind‑hole and bore inspection

Built to inspect blind holes and short bores, the tool’s geometry and adjustable setting ring allow secure positioning at the target depth. The three‑point contact ensures that the effective diameter is taken at a consistent plane, which reduces eccentricity errors inherent to single‑point probes. This design advantage supports reliable quality control in component assemblies, small housings and precision turned parts.

Measuring faces and handling that support accuracy

The micrometer is fitted with carbide measuring faces, providing wear resistance where surface contact occurs most. An analogue vernier with a reading step of 0.001 mm permits fine interpolation, while the robust spindle mechanism yields a predictable measuring motion. Together, these features lower measurement uncertainty and extend service life in routine inspection tasks.

Standards, traceability and workshop integration

Manufactured to DIN 863 standards, the device integrates easily into standard inspection routines and documentation. The compact form factor and light handling characteristics make it a practical choice for bench inspection or fixture checks. For operations seeking consistent measurement procedures, the micrometer complements existing gauges and contributes to a reproducible measurement chain.
