The Marine Anemometer WS-12 is an instrument for wind speed and direction. It can measure relative wind speed (accuracy ±5%, min 0.1m/s), relative wind direction (accuracy 1°). The WS-12 wind sensor must be reading representative values for the wind and therefore the wind sensor must be reading clear wind, unobstructed by any wind shadow from structures. -
