M304.319 Setting Gauge for Micrometres — 275 mm, Thermal Protection (Metav IndustryLine)

The M304.319 is a precision setting gauge for external micrometres, designed for workshop and laboratory use where consistent reference lengths and stable readings are required.

• Nominal length 275 mm
• Accuracy ±0.0035 mm
• Equipped with thermal protection
• Flat measuring faces, D 8 mm

Improve calibration reliability with traceable reference performance

The setting gauge serves as a stable reference for micrometre adjustments and routine verification tasks. With a nominal length of 275 mm and an accuracy of ±0.0035 mm, the gauge reduces uncertainty in the zeroing and checking of external micrometres, helping to maintain consistent measurement chains. The precision specification supports quality processes in machine shops and metrology benches, translating technical performance into measurable uptime and fewer instrument-related errors.

Maintain stable readings under varying shop conditions

Thermal effects cause the largest short-term drift in small-length standards; the integrated thermal protection minimises temperature transfer during handling, so readings remain repeatable between successive checks. The gauge is supplied with flat measuring faces and a diameter of 8 mm that suit standard micrometre anvils, while the modest weight (0.4 kg) and compact form factor permit quick positioning without sacrificing rigidity. These design choices reduce operator influence and improve reproducibility during calibration routines.

Seamless integration into workshop workflows

Classified within the standard range for length references (suitable for maximum spans up to 300 mm), the gauge bridges bench and workshop needs: long enough for broad applicability yet short enough for single-person handling. Use as an accessory for setting external micrometre screws or as a length master for periodic checks, thereby shortening inspection cycles and supporting stable production tolerances. The robust construction and targeted features make it an effective tool for quality control and process assurance in industrial metrology.
