The Roundtest RA-120/120P roundness measuring instrument features a ±1000μm wide range detector and precision turntable to provide best-in-class rotational accuracy in compact roundness measuring instruments. A dedicated processor controls all measurements and operations via a control panel in the main unit.
- Digital Adjustment Table (DAT) function digitally displays the centering and leveling adjustments on the turntable to make workpiece placement much easier
- Large color backlit LCD screen shows easy-to-understand measurement results and graphs to easily check forms and set notch processing
- Notch processing excludes data by notches or scratches if desired
- Model RA-120 has a built-in high-grade thermal printer provides instant measurement analysis results, graphs and comments
- Model RA-120P is PC-based and features a Windows graphical interface for excellent usability and advanced functions
