SEM-S110 Non-contact Road Surface Condition Detector

SEM-S110 is a non-contact road surface condition detector that uses remote sensing technology to avoid damage to the road, thereby eliminating the disruption to traffic caused by installing a road weather station. Multispectral measurement technology allows accurate detection of the thickness of ice, snow and water on the road surface.

SEM-S110 is a non-contact road surface condition detector that uses remote sensing technology to avoid damage to the road, thereby eliminating the disruption to traffic caused by installing a road weather station. Multispectral measurement technology allows accurate detection of the thickness of ice, snow and water on the road surface.

The SEM-S110 detector is the best choice for road conditions where buried road sensors are inconvenient or impossible to install. Remote sensing installation means no road closures or road cutting are required, making installation safe and convenient. Low maintenance makes it an ideal choice as part of a road weather system. It can be installed on existing weather stations or other buildings with an unobstructed view of the road surface.

The SEM-S110 detector is installed in an all-weather, durable housing to ensure it withstands adverse weather conditions, allowing it to provide accurate data in all weather conditions.

By providing road condition information, the SEM-S110 detector provides road management departments with accurate monitoring data to take response measures before road safety is endangered.
