Setting standard for micrometers M304.321.4 — 875 mm, ±0.009 mm accuracy (Metav IndustryLine)

The M304.321.4 setting standard for micrometers is designed to provide a stable reference for calibrating and setting outside micrometers across long measuring spans, with thermal protection for consistent results in workshop conditions

• 875 mm nominal length
• ±0.009 mm rated accuracy
• Spherical measuring faces
• Integrated thermal protection

Precise long-range reference for reliable setups

This setting standard offers a nominal length of 875 mm combined with a rated accuracy of ±0.009 mm, which supports precise adjustment of long-range micrometers and reduces rework. The long nominal dimension is paired with a modest mass of 1.3 kg, enabling stable single-handed positioning while limiting thermal gradients. The numerical specification communicates measurable performance and facilitates quality planning and inspection routines.

Stable contact design reduces measurement uncertainty

The gauge uses spherical measuring faces, which ensure defined contact geometry when setting the faces of outside micrometers; this design reduces sensitivity to slight angular misalignment and makes the procedure more repeatable. The inclusion of thermal protection helps to mitigate temperature-induced expansion during typical workshop operations, so the reference length remains closer to its calibrated value and traceable measurements are easier to maintain.

Practical benefits for production and quality control

As a workshop-grade metrology accessory from Metav IndustryLine, this setting standard streamlines routine calibration tasks and supports faster changeovers by shortening the time required to establish a reliable zero. The clear numerical accuracy and robust construction make it suitable as an in-process reference for manufacturing lines, inspection benches and measuring rooms where reproducible settings translate directly into fewer scrap parts and higher throughput.
