The Anemometer includes both wind speed and wind direction sensors.

The sensor is made of rugged components stand up to hurricane-force winds, yet are sensitive to a light breeze. Includes sealed stainless-steel bearings for long life. The range and accuracy specifications of this unit have been verified in wind-tunnel tests (information available upon request).

A model 7911 Anemometer reported wind speeds of 175 miles per hour before its tower collapsed during hurricane Andrew, 1992.

In areas where icing of the anemometer is a problem, use Anemometer Drip Rings to deflect water from the joint between moving parts.
