Typical Walking Profiler™ Application ROADS actual profile International Roughness Index(IRI) grade assessment of local surface detail AIRPORTS runway profiles cross slope SPECIAL AREAS car parks walkways CALIBRATION roughness measuring equipment national local standards DRAINAGE levels flow checking WEIGH-IN-MOTION site assessment BRIDGES tolerance assessment static deflection BUILDING SLABS profile level

The Walking Profiler™ enables accurate recording of measurements for actual profile, grade and level for surfaces such as paved roads, footpaths, runways, building slabs and sporting surfaces. This compact and easy-to use device is pushed over the surface to be surveyed. The on-board computer calculates and displays results (graphics and tables). The International Roughness Index (IRI) output from this device meets World Bank Class 1 Profilometry requirements. The system comes with a basic Footworks software package that provides profile and IRI. An advanced version of the Footworks software is available which provides additional information including straight edge emulation and California Profilograph emulation. Walking Profiler™ General Specifications Outputs: True profile height and grade against distance Speed of operation: Controlled walking pace, with audible speed prompt Availability of data: US units/ metric units/ imperial units/ displayed immediately at end of run Sampling interval (length): 241.3 mm or 9.50 inches Height measurement precision: ±0.01 mm or ±0.0004 inches per step Height resolution: Less than .005mm or 0.0002 inches per step Profile accuracy: ±1.0 mm per 50 metres or ±0.04 inches per 50 yds of smooth surface(typical) Profilometry class: World Bank Class1 and ASTME950 Class1 IRI accuracy: ±0.16 metres per km or ±6.5 inches per 1000 yds (on high quality pavements) Distance accuracy: Typical error band ±0.1% to ±0.3% (texture dependent) Correlation with rod and level derived IRI: R² = 0.988 Maximum grade measurement: 1 in 6 or 9.5 degrees Minimum path curvature: 15 metres or 16 yds (radius) Laptop: Provided, IBM compatible, Windows operating system Warm up time: 10-20 minutes Battery Life: 8 hours Working surfaces: Should be dry, firm, mud and dust free. Paved surfaces should be swept free of stones and debris. Operating temperature and humidity: 0-45°C or 32 - 113°F, non-condensing Wavelength measuring limits: 0.5 metres to hundreds of metres or 0.5 yds to hundreds of yds, no defined upper limit.

QD30 Reflectometer On site quality control of road markings according to CEN specifications

The QD30 Reflectometer is a portable instrument with built-in facilities capable of measuring reflection properties of road surfaces and road markings observed by drivers of vehicles under day and road lighting conditions. The QD30 Reflectometer can measure both on plane, profiled and textured markings. The QD30 Reflectometer measures the reflection and calculates the mean luminance coefficient in diffuse illumination(Qd) in agreement with the EN 1436 specification. Built-in thermal printer and memory provide registration of measurement results and corresponding supplementary data. The calibration standard supplied with the QD30 is traceable to an accredited national standards laboratory. Calibration to an accurate and traceable reference makes measurements taken with the QD30 reliable and repeatable. Other features: Easy to operate Measures both dry and wet surfaces Measurements in full daylight Measures plane, textured and profiled markings Stray light compensated Direct digital read-out of the mean luminance coefficient in diffuse illumination QD RS 232 serial interface for data output, extended control, calibration and diagnostics Rechargeable battery Built-in thermal printer Carrying case Calibration standard
