Micrometer setting gauge M304.309 — 25 mm reference, ±2 µm accuracy (Metav IndustryLine)

The Micrometer setting gauge M304.309 is a compact 25 mm reference standard designed for setting and checking external micrometers in workshops and inspection environments.

• 25 mm nominal gauge with ±2 µm accuracy
• Flat measuring faces for stable contact
• Integrated thermal protection reduces distortion
• Compact 7 mm diameter, 0.1 kg for easy handling

Dependable reference accuracy for everyday metrology

The setting standard delivers a nominal size of 25 mm with an indicated precision of ±2 µm (0.002 mm), making it suitable as a reference for routine micrometer adjustments. The calibrated dimensional tolerance provides a reliable reference that reduces variability during tool set-up and quality checks. Thanks to the flat measuring faces, contact geometry is predictable and repeatable, which translates into fewer measurement cycles and a steadier production flow in machining or inspection tasks.

Minimised thermal influence and robust handling

Thermal effects are a common source of short-term measurement drift in the workshop. The integrated thermal protection on this gauge reduces the transfer of heat from the operator’s hands, maintaining dimensional stability during repeated use. Its compact form—a 7 mm diameter body at just 0.1 kg—permits comfortable handling while limiting thermal load and mechanical deformation, so adjustments remain consistent even in busy production environments.

Streamlined traceability and workshop efficiency

As an accessory for micrometer set-up, the gauge supports faster tool changes and less downtime by providing a quick, verifiable reference dimension. Traceability elements such as the included GTIN and tariff number support inventory and customs processes, while the unit’s form factor keeps it immediately at hand on the metrology bench. The combination of repeatability, compactness and process efficiency makes this gauge a practical companion for quality control routines and fixture set-up.
