HY-RSS11E/12E/13E non-contact road surface state detectors, thanks to remote sensing technology it’s taken, it can not only avoid damage to the road,but also traffic interference during its installation. Multispectral measurement technology enables accurate detection of thickness of ice, snow, water on surface of the road.

HY-RSS11E is the most popular one, and we release more cost-effective road state sensor HY-RSS12E and RSS13E in 2020 to cater for projects with lower budget.
