WindObserver II Ultrasonic Anemometer

The WindObserver II provides wind speed and direction data via 1 digital and 3 analogue outputs and features an IP66 rated stainless steel housing, which is particularly suitable for use in salt-water environments. The anemometer also has an optional anti-icing heating option enabling the sensor to operate effectively in extreme environmental conditions, like those experienced at high altitude or at sea. The WindObserver II has been type approved by the Lloyds Register for use in marine and offshore applications.
