The Vaisala Surface Patrol Pavement Temperature Sensor is a mobile temperature sensor used to detect possible freezing temperatures on the pavement. It features a non-contact infrared sensor for measuring pavement temperature, and also measures air temperature. The easy to- use Surface Patrol is valuable for large agencies, such as Departments of Transportation, all the way down to smaller companies with only a few trucks. The Surface Patrol pavement sensor is mounted outside your vehicle and continuously monitors road surface temperatures, providing instant feedback on road surface conditions. The Surface Patrol has a separate air temperature sensor and cabling so that it can be placed away from direct sunlight for accurate readings. The data retrieved from the Surface Patrol is accurate and real-time, making it a reliable method for collecting pavement information.
