Wind Watcher Data Logger w/#40

The WindWatcher provides basic wind speed, 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. The addition of a NRG #200P wind vane (optional) will provide wind direction data - remember a 3 conductor signal cable and mounting mast are required when adding a vane. 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, Dcell battery and enclosure.

Features:

ü      Simple to use

ü      Inexpensive turbine performance verification

ü      Operates on a single D-cell battery for one year

ü       Calculates power in the wind
