KEY FEATURES:

  • The most accurate, dependable, and long term calibration stability of any profiler on the market
  •  Unique “Stop & Go” feature permits IRI and RN data to be collected in urban areas within traffic 
  • The RSP modular design allows for easy upgrades up to 21 lasers (three of which can be optionally macrotexture lasers), 2 accelerometers, and one inertial motion sensor
  •  Measurements referenced to linear chainage and Differential
  •  Geographical Position System (DGPS)
  •  Real-time profile data calculation and storage
  •  Optional GPS and digital photo logging can be stored with profiler measurement data Optional texture lasers can be used to collect real-time Mean Profile Depth (MPD) macro texture
  •  Optional 100 mm line lasers improve profile measurements on textured surfaces
