BKC-ANM - Includes both wind speed and wind direction sensors. Rugged components stand up to hurricane‐force winds, yet are sensitive to a light breeze. Includes sealed bearings for long life. The range and accuracy specifications have been verified in wind‐tunnel tests. In areas where icing of the anemometer is a problem, drip rings deflect water from the joint between moving parts
