The OWI-430 DSP-WIVIS™ is the most advanced present weather and visibility sensor ever made.

The fully automated instrument provides accurate visibility, present weather and precipitation measurement in a single sensor. This next generation intelligent sensor uses all digital signal processing (DSP) for no-drift high-accuracy results. A patented environmentally adaptive algorithms use artificial-intelligence technology derived from over 100 million field hours of real-world data from our sensors installed around the world. The result is the most advanced weather sensor in the world.

The DSP-WIVIS™ measures visibility and detects and quantifies rain, snow, drizzle, freezing and mixed precipitation conditions. The sensor is designed for year-round continuous operation in all climates from Antarctica to tropical rain forats. This advanced weather sensors provide critical weather information to airport, highway, military, research and meteorological weather information systems all over the world with over 2000 sysyems fielded. Sensing the environment is not a sideline business for us - it is our primary focus. When you need superior present weather information and high reliability, nothing else can match the DSP-WIVIS™
