• All the features needed for a wide variety of water sampling requirements

• Retractable pull handle and heavy-duty wheels provide easy transport
• Weathertight enclosure for the battery prevents accidental wetness
• Quick-disconnect pickup hoses can be stored inside the enclosure lid for easy transport

The WS705/755 samplers combine all of the features you need for stormwater, industrial discharge, water and wastewater, or rivers and stream sampling. Sample size control allows individual time-weighted samples or full-bottle discrete samples. Sample interval controls the time between individual composite samples or enables 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. An automatic 15-second back-flush cycle cleans debris from the strainer and empties fluid from the hose to prevent contamination.

WS705 sampler features one pump and bottle for most composite/discrete sampling applications. WS755 has two pumps and two bottles, and offers the unique ability to set the sampling mode for each pump and bottle individually. This allows time-weighted composite sample and a discrete sample simultaneously, or you can take two individual time-weighted samples with different sample sizes for each pump.

Order the optional stormwater kit to trigger the sampler for stormwater monitoring applications; includes a rain sensor, flow sensor, and auto-drain rain gauge all in one package.
