The WS705 single-bottle composite/discrete water samplers combine all the features needed to meet a wide variety of water sampling requirements, including those for stormwater, industrial discharge, waste collection, rivers, streams and water and wastewater treatment. The WS705 sampler's state of the art water sampler controller gives you complete control over your water sampling process.  With sample size control, you can take individual time-weighted composite samples or full-bottle discrete grab samples in a 9 litre sample bottle.  The sample interval control allows you set the time between individual composite samples or enable the external trigger mode for flow proportional sampling.  A start delay timer allows you to start multiple composite/discrete water samplers in the field at the same time, or to delay drawing a water sample after a triggering event so that your water sample better represents the water source.
