Mitutoyo RA-120 Roundness/Cylindricity Measuring System - 211-543A
Roundtest RA-120 Compact Roundness Measurement
The Roundtest RA-120 is a compact, affordable, and simple-to-use device for measuring part geometry on the shop floor. It also provides such superb data analysis capabilities as required with laboratory roundness measuring instruments and has a ±1000μm wide range detector and precision turn table with excellent rotation accuracy. The RA-120 is a dedicated processor based model which controls all operations via the control panel incorporated in the main unit.
Best-in-class rotational accuracy for compact roundness measuring instruments. Fine adjustment on both X- and Z-axes.
- Multiple analyses through simple operation
- D.A.T. function
*except for centering/leveling device:
- Analog mic-head - Scaled Z-axis
- Continuous ID and OD measurement
- Display function for various graphs
- High-precision air bearing
- Wide-range detector
- Supports 15 languages
