Product Description

Inspeed Vortex Pole Mount Anemometer  This rugged wind speed anemometer with dual digital display can handle speeds from 3 mph to over 125 mph.

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! 

Accuracy:
+/-4% from ~10 to ~50 mph
+/- a few tenths of a mph from ~4 to ~10 mph
The accuracy above 50 mph is presumed to be excellent (based on data from the rotor manufacturer), but no precise laboratory calibration has been obtained.
