The HR-MP is a passive changer rack that enables the fast interchange of probe modules or styli configurations during measuring cycles, guided directly by the CMM measuring software. The HR-MP rack is designed to store probe modules safely and securely, providing them with protection from airborne contamination.

The HR-MP-A3 can be mounted to a HR-R rack and therefore, does not need to placed on the machine table separately. It includes a 3-port module with an adapter to mount it on the side of a HR-R Rack.
