MEASNET High accuracy anemometer
This anemometer comes with a specific and unique calibration certificate from a MEASNET recognised laboratory. This means that the anemometer is guaranteed to have an accuracy better than 1% and a resolution better than 0.1m/s
The MEASNET anemometer is a good option where there's conflict of information between different wind speed sensors. In general anemometers degrade over time and their precision and accuracy suffers too. With the MEASNET anemometer you have the piece of mind to be guaranteed the highest precission over a year.
