Hand pushed laser flatness meter is a portable road surface flatness detection device that uses laser ranging technology combined with inertial compensation system to measure the local flatness of pedestrian walkways, small roads, construction sections and other areas with high precision. Compared to vehicle mounted systems, it is more suitable for detecting low-speed, small range, or areas that are difficult for vehicle mounted devices to cover.
 
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 operating system, for data acquisition, storage, printing and data processing, calculation and generate reports and to facilitate further analysis.
