Yankee Environmental Systems, Inc. Total Precipitation Collector TPC-3000

The Model TPC-3000 Total Precipitation Collector is a state-of-the-art automated wet deposition sampler designed for remote operation. It consists of a wet deposition collection bucket that is normally covered by a motor operated lid during non-precipitation events. The user periodically visits the system to recover its precipitation sample bag for off-site lab analysis. Its software-controlled Opti-Grid� precipitation sensor provides reliable and repeatable open/closed decisions, while ignoring false triggering from insects. It represents a major improvement over older technology that often missed the earliest phases of light precipitation. As the earliest precipitation phases tend to contain higher concentrations of pollutants, this lack of sensitivity biased historical data. The TPC-3000 is also suitable for research on chemical/biological (chem-bio) agent dispersion and emergency response teams providing in-situ collection after a terrorist attack.
