The 7911 vane anemometer for the Weather Wizard and Weather Monitor stations (also compatible with the Vantage Pro and Pro 2 stations) provides wind speed and wind direction measurements. The anemometer is rugged and can withstand hurricane-force winds, but is also sensitive to very low wind speeds.

The anemometer has been tested in a wind tunnel and meets the limiting characteristics below. It recorded up to 282 km/h during Hurricane Andrew in 1992 before breaking.

A 12m 4-conductor cable is supplied with the vane anemometer. 

Fixing to a tube/mast with a maximum diameter of 5 cm.

This vane anemometer also exists in a version with a more vertical offset arm: Reference 6410 (see associated product).
