App allows smartphone to control surface measurement drive unit
Mahr Federal has introduced a new Android® app that lets users 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 to measure such roughness parameters as Ra, Rz, Rmax, Rt, and Rq. Resulting profiles can be zoomed using multifinger gestures for instant analysis, saved, converted to PDF files, synched, and e-mailed for display and analysis on other devices.
The app can be downloaded from Google Play for Android. A free demo version is available for seven days, and the full, licensed version can be purchased for automatic download. No operator training is required, as operational elements follow typical and well-known Android user interface styles. The app uses a standard R-profile filter and measures in accordance with DIN EN ISO 16610-21 (digital phase correct).
