Consistent calibration performance through standard conformity

The ring is manufactured from hardened and lapped gauge steel, a choice that delivers both mechanical stability and a low-wear measuring face. Compliance with DIN 2250 and DIN 286 and the specified JS 3 tolerance class means the component functions as a dependable master for setting comparators, plug gauges and other inspection equipment. The standardised tolerance ensures interchangeability with other calibrated masters and supports traceable measurement routines in production and quality control.

Robust geometry that aids repeatable measurement

The Form C profile provides reliable centring and handling during routine use; combined with the lapped finish, this minimises local contact distortion and reduces the risk of measurement drift over time. The ring’s Ø 42 mm nominal diameter makes it suitable as a setting standard for instruments that require a mid-range reference size. The compact, symmetric design simplifies use in both bench metrology and shop-floor inspection, translating the material and finish choices into long-term dimensional stability.

Practical application and procurement confidence

Built for use in gauging, inspection and calibration tasks, this ring gauge is a practical master for workshops, toolrooms and small calibration labs where a durable reference standard is required. Supplied under the Metav IndustryLine brand, the product benefits from Metav’s supply chain and quality assurance approach—making high-precision measuring aids more accessible to industry. For buyers seeking dependable masters without sacrificing availability, the construction and conformity of this ring support efficient measurement workflows and reduced rework.
