With fully automated measurements, the CS8900 is a significant advancement for testing compliance with ADA (Americans with Disabilities Act) Access criteria for sidewalks. Eliminate random and time consuming measurements with manual tools like straightedges and digital levels. With the CS8900, users can add pictures and GPS positions to their sidewalk data, which can be exported in custom formats, including PDF and GIS.
Profile Device Classification/Rating: ASTM E950 Class I equivalent • World Bank: Class 1 profiling device
Test Results and Data Outputs: Cross-slope • Running Grade • Evenness • Ride Index (e.g. WPRI,IRI, HRI, PRI, RN) • Data Formats: PDF, Excel, CSV/ASCII, ERD/PPF (ProVal), GIS, GPX/KML and user specified formats
Localized Roughness (Evenness): Dimensions of bumps/dips measured with maximum amplitude of peaks and troughs calculated • User configurable templates for separately calculating dimensions of bumps and dips
Measurement Units: English/Metric (variable, re-writeable)
Operating Speed: 0–3 mph (0-5 kph)(slower speed for best results on rougher or coarse surfaces)
