  • 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
