This wind speed sensor comes with a specific and unique calibration certificate from a 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 calibrated 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 calibrated (MEASNET) anemometer you have a guaranteed highest precision for a year.
