Wind Data Evolved

NAVIS Anemometers consist of wind speed and/or wind direction sensors which wirelessly transmit real time wind and temperature data to your paired display unit. Read instant data including, average and maximum wind speed, direction, temperature and view history graphs.

With the NAVIS Data Logging System you get all of the NAVIS benefits plus a complete data history running up to 168 consecutive hours stored on exchangeable SD cards.
