The Navis WR3B Anemometer is a portable wireless anemometer with a long range. It features a portable display unit and a sensor suitable for permanent or temporary installation. The sensor with bearings and the long-lasting battery ensure a large period of time without maintenance. The sensor sends data every 2 seconds, providing immediate information about wind speed anywhere within a radius of 400 meters from the sensor. Each sensor has its own address, allowing multiple anemometers to operate in close proximity without interference.
