Roundtest RA-H5000
High-precision Roundness Measuring System

The Roundtest RA-H5000AS/AH has been developed by Mitutoyo
to provide the world's greatest degree of accuracy in roundness
measurement. High precision has been achieved without
sacrificing speed through a process involving constant redesign,
prototyping and experimentation. This development is based on
Mitutoyo's years of experience in the industry, along with
cutting-edge technology in the field of shape measurement.
