25mm Tube Wall Micrometer With Spherical Anvil, 0.01mm Graduation, Ratchet, In Case - Metav IndustryLine

Take advantage of precise pipe‑wall measurement in a compact format: the combination of a 0–25 mm measuring range with a ball anvil and a 0.01 mm graduation ensures accurate contact on curved surfaces and clear readout for quality checks. The hardened measuring faces and ratchet stop provide repeatable results and protect the spindle, so production sampling and inspection cycles remain consistent.

M309.044 Micrometre Screw Gauge — Pipe‑wall measure 0–25 mm, 0.01 mm graduation (Metav IndustryLine)

M309.044 is a precision micrometre designed to measure pipe wall thickness up to 25 mm, combining a ball‑shaped anvil for secure contact on curved parts with a matt‑chrome thimble for easy reading

• Precision 0.01 mm graduation
• Ball anvil for curved surfaces
• Ratchet stop for consistent measuring force
• Hardened measuring faces and matt chrome thimble

Consistent accuracy for curved workpieces

A micrometre built specifically for pipe and tubular inspection reduces the uncertainty that comes from measuring rounded geometries. The ball anvil contacts the workpiece with a defined surface geometry, so contact points remain stable even on small radii; coupled with the ratchet stop, the applied measuring force is controlled, reducing operator‑induced variation. The instrument’s graduation of 0.01 mm and the documented accuracy ±0.004 mm make it suitable for routine quality checks where reproducible values are required rather than only rough estimates. This saves time at the inspection bench and supports fast pass/fail decisions.

Repeatable handling that speeds up inspection cycles

Ergonomics and repeatability are decisive in busy workshops. The micrometre’s ratchet mechanism ensures the same final spindle travel each time, which reduces rework and improves throughput on batch inspections. The lacquered frame offers good grip and thermal stability compared with bare metal finishes, while the matt‑chrome thimble improves contrast for quicker readings. Together these features provide a measurable productivity gain: fewer measurement repeats and shorter cycle times for standardised quality control routines.

Robust finish and workshop readiness

Designed for practical use, the measuring faces are hardened to resist wear from repeated contact, extending service life and preserving calibration. The frame is lacquered and the measuring drum is matt‑chrome plated, protecting key surfaces from corrosion and shop contamination. Delivery includes a protective case for safe transport and storage, so the instrument arrives ready for use on the shop floor or in the inspection room. For applications that routinely inspect pipe wall thickness from 4.7 mm, the construction and contact geometry conserve accuracy across many measurements.
