WINDWATCHER
Wind Watcher Data Logger

Wind Watcher Data Logger The WindWatcher provides basic wind speed, direction, and wind power density information in an easy-to-install, easy-to-use package. Instantaneous and historical wind data are available at the touch of a button. Stored data can be used for prediction or verification of wind turbine performance.

Inexpensive totalizers or weather stations that provide only average wind speed don't give a complete picture of your site's wind energy potential. The WindWatcher provides a professional quality, complete assessment.

The WindWatcher includes a #40 anemometer, 30 m cable, 406 mm (16 inches) sensor stub mast, grounding cable, D-cell battery and enclosure.

Features:

Simple to use
Inexpensive turbine performance verification
Operates on a single D-cell battery for one year
Calculates power in the wind
