The world’s only UCI hardness tester suitable for fully automated production lines with the possibility of 100% process monitoring in mass or series production

100% process monitoring in mass or series production

With its 19″ housing dimensions, the SONODUR R is ideally suited to be used in fully automated production lines and as a tabletop device. The familiar android-based software of the SONODUR 3 is optimally adapted to the clear 7″ LED touch screen of the SONODUR R.

Thanks to USB and a fully isolated, digital I/O interface, the device is currently the only fully automatable UCI hardness measuring system in the world. Set points can be used to directly control actuators such as good/bad sorting switches.

The SONODUR R combines all the advantages of the SONODUR 3 mobile hardness tester with the requirements of a device for integration into a fully automated process line.

All UCI SONODUR handheld and motor probes can be used without restrictions due to high-resolution, digital signal processing technology. The instrument works with wired probes of the SONO H/M/S series. These are available in different versions and test forces. Hand-held probes are available with standard test loads of 10 N, 30 N, 49 N and 98 N. Motor probes are available in 1 N, 3 N and 8.6 N versions.

The main areas of application are the measurement of series parts after heat treatment and/or surface processing as well as coating hardness measurement on gravure cylinders.
