Product Code: Vortex-P-30
Pole Mount Anemometer
Rugged anemometer with dual digital display handles speeds from 3 mph to over 125 mph. Comes with exterior grade wire. The Pole Mount anemometer is great for home or mobile use where AC power is not available. Pole not included. Comes with 30m of cable (more available on request).
Knowing the wind speed is not only useful - it's informative and it's fun. The Vortex Pole Mount Anemometer is an inexpensive way to provide you with accurate wind speed in places where AC power may not be available.
Mount the head and rotor to your own pole or roof bracket, bring the wire in through a window or some other hole, and stick the display on the glass, a window, or anywhere you want. Connect the red & black wires and Voila!
The Vortex Pole Mount Anemometer display is a high quality, Sigma Sport bicycle computer. Speed range is approx. 5 to around 150 mph, although the calibration has only been verified from 5 to 50 - we did not find a wind tunnel with 150 mph calibration facilities! Check out the wind sensor specifications for details. Battery life is around 1,000 hours of continuous use. Some we have tested on our home lasted for well over a year on the original batteries!

A further note on accuracy
The Vortex™ anemometer is NOT sensitive to how it is held in the wind, provided the head is held horizontal and the air flow is not obstructed by the user (i.e. you do not have to face into the wind).
IMPORTANT NOTE ABOUT AVERAGE WIND SPEED:
WORKAROUND : if you want to know the real average wind speed - even with spells near zero, do the following: reset the computer, note the time. When desired, simply divide the total number of wind "miles" on the display by the number of hours since reset.
