Brookhaven Automatic Sequential Precipitation Sampler
An Automatic Sequential Precipitation Sampler was designed and constructed at Brookhaven National Laboratory to collect precipitation samples for chemical analysis. The sampler is designed to collect both wet and frozen precipitation and to exclude dry fallout between precipitation events. The sampler consists of a large box containing a turntable holding 30 sampling bottles. Precipitation enters through a funnel on the top of the box. Between periods of precipitation, the funnel is closed by a movable cover which is actuated by a rain sensor when precipitation starts. Sample bottles are changed automatically and periodically from the time the cover opens. Times of cover opening and closing and of bottle changing are recorded on an event recorder. The sampler has operated successfully since June 1976.
