• Flat measuring faces
• Integrated thermal protection

Reliable reference for precise micrometre calibration

A solid reference bar delivers the foundation for repeatable measurements. The compact reference offers a 225 mm nominal length combined with ±0.0035 mm declared accuracy, which corresponds to roughly 3.5 µm. This level of precision reduces setup uncertainty when adjusting outside micrometres and supports consistent part inspection. The flat measuring faces minimise contact variability, making the standard well suited to both workshop and laboratory environments where reproducibility matters.

Temperature stability that preserves measurement integrity

Thermal effects are a common source of error in length standards. The supplied item features thermal protection, which mitigates short-term temperature influences during handling and brief exposure to ambient changes. Reduced thermal drift means fewer false rejections and less rework, improving throughput in calibration routines. For everyday calibration tasks this stabilising function directly translates into lower process variance and more reliable traceability chains.

Compact design for routine use and easy handling

Weighing 0.3 kg, the reference is easy to position and manipulate on a workbench or within a calibration jig without compromising stiffness. The flat measuring faces provide a clear seating surface for outside micrometres, simplifying alignment and reducing operator-induced error. As an accessory-class reference, the gauge integrates smoothly into existing metrology workflows and complements laboratory standards by offering a practical compromise between range and handling convenience.

FAQ

How precise is the setting gauge for routine calibration tasks? The setting gauge M304.317 offers a declared accuracy of ±0.0035 mm (about 3.5 µm), suitable for high-precision workshop and laboratory checks of outside micrometres.

Can this reference be used with all outside micrometres? The reference bar is intended for setting and checking outside-measuring micrometres; compatibility depends on the anvil geometry of the micrometre, but the flat measuring faces support standard contact geometries.

Does the thermal protection eliminate the need for temperature-controlled rooms? Thermal protection reduces short-term drift and handling effects, improving stability during use; for highest-accuracy traceable calibrations, a controlled environment remains best practice.
