RA-120P
The Roundtest RA-120 120P are 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.
The RA-120P is a PC based model which controls all operations via ROUNDPAK
software optional.
