Made of a one-piece durable plastic rotor and low-friction Teflon bearing, the wind meter communicates directly to the magnetic field sensor in your smartphone. Downloadable, free app allows you to register actual, mean and max wind speed on a smooth graph that supports both drag and pinch to zoom in on all the details.
Compact, pocket friendly and practical!
With its compact two cup design, inspired by professional anemometers, the Vaavud? wind meter is accurate, practical and truly pocket friendly. It has a one piece durable plastic rotor and low friction PTFE bearing. Reliability and long service life are assured through the use of revolutionary electronic-free technology, communicating directly with the magnetic field sensor in your smartphone. Free Vaavud? App available from the Apple App Store and Android Market!
The Vaavud? App measures and displays wind speed in commonly used units of measurement. It has a neat and clean interface that shows the most important wind characteristics: actual, mean and max wind speeds. The smoothed graph provides additional data on variations in strength as well as a quick overview. The graph supports both drag and pinch to zoom so data can be viewed in fine detail.
Precision at your fingertips!
The Vaavud? wind meter has a wind range from 4 knots up to 48 knots (2 m/s up to 25 m/s). Accuracy is the lower of +- 4% and 0.4 knots (0.2 m/s), with testing and calibration confirmed in the professional wind tunnel at the Technical University of Denmark. The cup anemometer design makes the Vaavud? less sensitive to the way it is pointed; a weakness in impeller type wind meters.
