The SurPro is an accurate and effective device for measuring surface profile and roughness characteristics of any placed surface, including roads, structures, runways, and floors. It is a Class 1 profiling unit and uses patented inertial technology.
The SurPro is a fully automated, portable unit. It weighs just 42 pounds. It can be brought onto any job site and be collecting data in a matter of minutes. The SurPro collects true elevation profiles, displays the results, saves the data, and executes user-configurable analysis to provide numerical and graphical representation of the profile and several roughness indices.
The SurPro calculates IRI (International Roughness Index), RN (Ride Number), PI (Profilograph Index), and Boeing Bump Index.
The device collects both longitudinal and transverse profiles as well as elevation and grade information for any placed surface.
