Setting gauge for micrometres M304.321.3 — 825 mm nominal length, ±0.009 mm accuracy, Metav IndustryLine

The Setting gauge for micrometres M304.321.3 is a precision reference instrument for setting and checking outside micrometres in workshop and laboratory environments, designed for long-format calibration tasks where stability and repeatability are essential

• 825 mm nominal length for large standards
• ±0.009 mm measurement accuracy
• Ball-ended measuring faces for repeatability
• Integrated thermal protection for stable readings

Ensure measurement accuracy across production

The gauge offers a clear basis for reliable micrometre adjustment: with a nominal length of 825 mm and a stated ±0.009 mm tolerance (equivalent to 9 µm), the instrument provides a stable reference across long spans. This level of precision supports consistent set‑up of outside micrometres, reducing variation between operators and lowering the likelihood of out‑of‑tolerance parts. The numerical specification is expressed as an objective performance parameter so that measurement uncertainty can be incorporated into quality control plans and process capability studies.

Minimise thermal and contact‑induced variability

Built with thermal protection and ball‑ended measuring faces, the reference is engineered to limit two common sources of error: thermal expansion and point loading at the contact. The thermally shielded design keeps readings stable in typical workshop conditions, while the spherical contact geometry (diameter 16 mm) reduces local stress and improves repeatability when setting micrometres. The instrument’s mass of 1.3 kg contributes to steady positioning on a workbench without being cumbersome to handle during routine calibration tasks.

Integrate into routine calibration workflows

Supplied as a robust accessory within the Metav IndustryLine portfolio, the gauge supports efficient calibration routines and traceable documentation. As a workshop reference, the device is suited to regular verification of outside micrometres and can be incorporated into ISO‑aligned internal procedures; its clear technical data simplifies the creation of test logs and measurement reports. Choosing a well‑specified standard from a recognised supplier helps maintain production continuity and underlines a commitment to precise, reproducible inspection results.

FAQ

What is the primary purpose of this setting gauge? The setting gauge M304.321.3 is intended as a reference for setting and checking outside micrometres, providing a stable nominal length and defined accuracy for calibration tasks.

Which measurement tolerance can be expected from the device? The instrument is specified with an accuracy of ±0.009 mm, which corresponds to 9 µm and serves as the basis for traceable micrometre adjustment.

Can the gauge be used in a standard workshop environment? Yes, the gauge’s thermal protection and robust design make it suitable for routine workshop calibration and use as a bench reference.

How does the ball-ended face benefit micrometre setting? The ball‑ended measuring faces (16 mm diameter) reduce local contact stress and improve repeatability when transferring a reference dimension to an outside micrometre.

Who supplies and supports this product? This gauge is offered under the Metav IndustryLine range and is supported by Metav Werkzeuge for enquiries and order processing.
