M303.131.S built‑in micrometer — 0–25 mm, 0.01 mm resolution (Metav IndustryLine)

The M303.131.S is a compact built‑in micrometer designed for machine and panel integration, offering planparallel measuring faces and a reliable locking function for repeatable small‑range measurements.

• Built‑in design for machine mounting
• 0–25 mm measuring range
• 0.01 mm analogue readout
• DIN 863 compliance

Consistent precision for repeatable measurements

Precision is the primary advantage of this compact micrometer. With a 0–25 mm measuring range and a fine 0.01 mm indication, the instrument supports precise sizing and quality checks where small tolerances matter. The spindle advances with a spindle pitch 0.5 mm, which—combined with the vernier‑style analogue scale—ensures predictable linear motion and traceable increments. Compliance with DIN 863 documents the mechanical accuracy and makes the device suitable for standard workshop inspection routines, ensuring that measurements are both reliable and comparable across shifts and machines.

Integration and robustness that reduce setup time

Engineered for in‑line installation, the built‑in form factor simplifies mounting into fixtures and control panels. The metric M9 thread and compact spindle Ø 6.5 mm make mechanical connection straightforward, while the low mass (approx. 0.1 kg) minimises dynamic load on moving parts. The matt chrome‑plated drum resists glare and surface wear, improving legibility and longevity in production environments. This combination of mechanical detail reduces setup iterations and shortens machine‑integration time, delivering a measurable improvement in process efficiency.

Secure handling and straightforward maintenance

Planparallel measuring faces provide stable contact geometry for external and step measurements, reducing orientation error during short‑range checks. A dedicated locking device holds the spindle position for transfer measurements or when replicating a setting across multiple parts. The analogue readout avoids electronics in harsh environments and facilitates quick visual checks on the shop floor. Routine care is limited to light cleaning and occasional lubrication of the spindle; the simple construction keeps downtime low and service straightforward, supporting continuous operation in demanding production contexts.
