Anemometer Vaisala WAA252 with heated cup

Non-freezing, all-weather wind set for arctic conditions
Fully heated anemometer and wind vane (heating in cups and vanes, sensor bodies and bearings prevent snow build-up and ice formation)
High performance, accurate wind speed and wind direction measurement
Low measurement starting threshold
Conical anemometer cups provide excellent linearity
