RoadWatch Road Surface Temperature Sensors From MS Foster & Associates, Inc.

RoadWatch, road surface temperature sensor
Road surface temperature sensors from RoadWatch Bullet use state-of-the-art infrared measuring, which assures accurate, real-time road surface temperature information critical to proper deployment of anti-icing and de-icing materials. With RoadWatch Bullet, the pavement temperature sensors create an alert of existing hazardous conditions for driver safety.

The RoadWatch Bullet, formerly the RoadWatch SS Road Temperature Measuring System, can accurately detect a one-degree change in road surface temperature in one-tenth of a second. An early warning system using pavement temperature sensors within the RoadWatch Bullet system alerts the driver when the road surface temperature dips below 37 degrees Fahrenheit. RoadWatch Bullet’s pavement temperature sensor system was originally developed to assist highway and public works departments determine when and where to apply road treatment chemicals, however, this innovative road surface temperature sensor can benefit all drivers and improve highway safety.

The road surface temperature sensor system, road surface temperature sensor, RoadWatch BulletRoadWatch Bullet, is already in use throughout North America and Europe. The pavement temperature sensor system uses its unique, early warning road and temperature sensors to tell city and highway departments along with airport officials when to treat road surfaces if hazardous driving conditions are created using the unique infrared temperature sensor to monitor road and pavement surface temperatures.

RoadWatch Bullet provides users with an unmatched reliability, approved performance of road treatment chemicals, while providing constant feedback on road surface temperature conditions. The road surface temperature sensor system can operate alone or can be integrated into other vehicle controls with easy installation. To protect the sensors monitoring the road surface temperature, the sensor is fully enclosed and has been environmentally tested to provide durability under extremely cold temperatures. The pavement temperature sensor operates in conditions from -40 to 150ºF.


If you already own a RoadWatch SS pavement temperature measuring system, the new RoadWatch Road surface temperature sensors offer backward compatibility, allowing you to purchase the sensor to connect with your existing cables, connectors, displays and converters. This allows you to stay up-to-date with the latest road surface temperature sensors without the added cost of a complete road temperature system.
