B002-B Road and Hand push type laser surface International Roughness Index (IRI) tester or Profilometer
The instrument is a new type of laser flatness gauge developed by xi'an zealchon Civil instrument graduate school on the basis of YLPY - F type and site construction requirements, convenient for construction units to use at any time.
It can test quality acceptance of the building, rebuilding, pavement engineering and no serious potholes and rutting disease, and the road surface roughness without water, snow, mud and normal traffic detection.
Precision can be up to 0.01 mm, to measure the surface smoothness of the asphalt, the reliability of generating high speed transmission measurement data into the computer processed by special software,it also can output calculation table and waveform figure .
Laser flat instrument host computer program is application software mating road flat instrument host supporting, the software can run on Windows XP operating system, for data acquisition, storage, printing and data processing, calculation and generate reports and to facilitate further analysis.
Technical performance
1. The flatness of measurable indicators:
The international roughness index IRI
Flatness sigma (can be reduced turbulence value)
2. The output:
All kinds of index number mileage pile number out-of-tolerance left picture right picture can be set
All kinds of index curve and the original data
3. The general technical characteristics:
Detection speed: 8 km/h continuous measurable distance: > 50 km
