DH-8/App and every Windows computer becomes a roughness measuring instrument

DIAVITE DH-8/App is best suited for permanent measuring stations.

Depending on the application, the DIAVITE DH-8/App can be connected to any tablet or PC. The software is easy to install. This way, you can transform any computer into a roughness measuring instrument. Take advantage of its new available options for data transfer, measurement storage and documentation, and so much more.

The App can be installed on several computers. Simply connect the analysis unit to the computer using a USB cable.
