Sauter AHMR 01 support rings are measuring accessories for Leeb hardness testers designed to stabilise the impact device on curved or irregular surfaces. These Sauter support rings improve measurement accuracy by ensuring correct positioning during hardness testing. They are used in hardness testing of metals where cylindrical or rounded components are being measured. The rings provide a stable contact surface for the impact device reducing measurement variation. They are commonly used in field inspection maintenance and quality control of pipes shafts and curved components. As support accessories they enhance reliability of Leeb hardness measurements.
