The MH20 and MH20i are manually operated probe heads that articulate to provide orientation of the probing axis.  MH20 provides non-repeatable orientation, while MH20i permits repeatable indexing at 15° increments marked on the A and B axes.  Both heads feature TP20 kinematic (magnetic) probe mounting, allowing stylus module changes without the need for re-qualification.  A range of shanks is available to suit most CMM quills.
