This product is a sampling device specially developed for non-point source pollution sampling problems that are difficult to deal with by traditional samplers. It is specially equipped with unique sampling modes such as rainfall triggering and flow rate proportionality. It is mainly used for non-point source pollution sampling, mainly agricultural non-point source pollution. Designed in view of the dispersion, uncertainty, hysteresis and duality of non-point source pollution, it provides more scientific data for agricultural non-point source pollution flux research and assists in guiding scientific fertilization and planting.
It has multiple sampling modes such as manual, flow trigger, and remote.
It has dynamic continuous proportional sampling function, and continuous and uninterrupted sampling during the whole drainage process.
It can be connected to an external flow meter to dynamically adjust the sampling rate according to the instantaneous flow change.
When it rains, bottle 1 collects the initial rain sample at a high sampling rate, and bottle 2 collects continuous mixed samples during the entire rainy period at a low sampling rate.
It is mainly used in surface source sampling scenarios.
