The NewSonic SonoDur-R 'Rack' is a UCI hardness tester designed for complete automated, 100% checks of mass-produced parts. The 19" desktop device performs rapid process monitoring (at one-second intervals) of mix-up testing procedures. Conforms to ASTM A1038.

The SonoDur-R is mainly used to test serial parts following heat treatment, surface processing or measuring coating hardness on gravure cylinders with highly-selective low-load motorized probes. 

The SonoDur-R is the world's only automated UCI measurement system that is fully system compatible thanks to its USB and fully-isolated, digital I/O interface. Good/bad sorting gates and other factors can be set up with setpoints to help facilitate your hardness inspection processes.

The SonoDur-R provides all of the features of the SonoDur2 mobile hardness testing device but can scale into a fully-automated process line.


All SonoDur manual and motorized probes are compatible with the SonoDur-R without restrictions. Simply connect each probe through a USB port.
