Campbell Scientific - Model 03301-L -Wind Sentry Vane

The 03301, manufacted by R. M. Young, is the wind vane included with our Wind Sentry Sets (03002, 03001). Although some customers have valid applications that require monitoring wind speed only (without direction), monitoring wind direction only (without wind speed) provides little useful information. For this reason, the 03301 is available for two purposes: As a replacement vane for a Wind Sentry Set that requires replacement of the vane only. As an "upgrade" for a customer that originally purchased only the anemometer and now wants to add the vane to make a complete Wind Sentry Set.
