Sun LabTek

The apparatus is used for detecting the road surface irregularity. It can be used either for concrete or asphalt pavements. The apparatus consists essentially of a beam with rigid wheels at the extremities and a wheel at the middle, which can detect any vertical deviation of the surface from a straight-line between the two wheels at the ends of the apparatus. Supplied complete with recording unit to obtain a graph of vertical deviations.

• Beam length: 3 m
• Scale: 2 mm increments up to 10 mm; 5 mm increments from 10 to 25 mm
• Max vertical deviation: ± 25 mm
• Weight approx.: 55 kg
