034B Wind Sensor

The 034B Wind Sensor combines wind speed and direction measurements in a single sensing unit. It installs in minutes and provides accurate, long-term, continuous monitoring in hostile environments. The sensor uses a quick-connect sensor cable which may extend hundreds of feet without affecting measurement performance.
