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 1000pm 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.
