​The key to the RoadWatch system is our unique sensor which measures both air and surface temperatures in Fahrenheit or Celsius.  Built rugged to last in the harsh environments where it is expected to operate. The system is designed to allow for easy component replacement should damage occur. Calibrated for life, you won't need to spend valuable time checking and adjusting. Designed to mount either on the mirror c-loop or in a variety of other locations, you have the flexibility to position the sensor where it will serve your needs best.
