Smartphone App Delivers Surface Roughness Measuring

Mahr Federal’s Android App provides users the ability to measure common surface roughness parameters using their Smartphones and other Android operating system devices. The MarSurf One App interfaces via Bluetooth with a Mahr RD 18 Drive Unit and probe that measures the most popular roughness parameters, including Ra, Rz, Rmax, Rt, and Rq. Resulting profiles can be zoomed using multi-finger gestures for instant analysis, saved, converted to PDF files, synched, or emailed for display and analysis on other devices such as PCs.

MarSurf One App is a very inexpensive and portable way to obtain surface roughness measuring capability. The App requires an RD 18 drive unit and probe, which come standard with MarSurf M 300 systems.

Users get a free seven-day demo version and can click the buy button to download the full licensed version automatically. No operator training is required as operational elements follow typical and well-known Android user interface styles. The MarSurf One App uses a standard R-profile filter and measures in accordance with DIN EN ISO 16610-21 (digital phase correct).
