Peristaltic Water Sampler

Simple to operate-- no programming required|Automatic 15-second backflush clears pickup strainer and hose|Optional kit available for storm water sampling|Global Water WS700/750 samplers combine all of the features you need for storm water, industrial discharge, water and wastewater, or rivers and streams. Sample size control allows individual time-weighted samples or full-bottle discrete samples. Sample interval control allows you to set the time between individual composite samples or enable the external trigger mode. Start delay timer allows multiple units to be set for concurrent sampling or to delay the start of sampling after an event for a more representative sample. WS700 sampler features one pump and bottle for most composite/discrete sampling applications. WS750 sampler has two pumps and two bottles providing the unique ability to set the sampling mode for each pump and bottle individually. This allows time-weighted composite sample and a discrete sample at the same time, or you can take two individual time-weighted samples with different sample sizes for each pump. An automatic 15-second backflush cycle cleans debris from the strainer and empties fluid from the hose to prevent contamination. Order the optional stormwater kit to trigger the sampler for storm water monitoring applications; includes a rain sensor, flow sensor, and auto-drain rain gauge all in one package.
