  VIS-430-DS is a state-of-the-art triple aperture, forward scatter visibility sensor. Unlike traditional two-headed visibility sensor designs, the VIS-430 does not require periodic field calibration. The VIS-430-DS is ideal for Road Weather Information Systems as well as Airport Automated Weather Observing Systems when present weather information is not required.
