Weather measuring equipment manufacturer Lufft has launched StaRWIS, a new easy-to-install and compact stationary sensor for road weather information systems based on a non-invasive, spectroscopic measuring standard. Designed for hard-to-reach or critical locations, the sensor is installed at a height between five and six metres and provides road and dew point temperatures, water film height, road conditions (dry, wet, ice, snow, critical and chemically wet), relative humidity, ice percentage and friction.
