YSI’s WS700 single bottle and WS750 Dual bottle samplers combine all the features you need to meet a wide variety of sampling requirements, including those for Storm water, rivers and streams, industrial discharge, water and waste water treatment and waste water collection.

If your samples need to be refrigerated the WS700R model is ideal for providing the same sampling functions and needs, but with the added benefit of keeping your sample refrigerated.

The WS705 and WS755 models provide the exact same functionality, but come with enhanced portability accessories, such as more ergonomic handles and durable wheels.

  • Sample Size
    The user can adjust the wastewater/stormwater sampler’s peristaltic pumps individually to one of 15 composite sample sizes from 50ml to 2 liters plus a full bottle discrete setting. The wastewater/stormwater sampler’s peristaltic pumps can be set to a single sample time interval from 5 minutes to 12 hours plus an external trigger mode setting for flow proportional sampling
  • Collection Control
    Trigger inputs to control sample collection. The sample bottles are each equipped with a float switch that automatically turns off the peristaltic sampling pump if the water bottle becomes full.
  • Two-in-One
    Does composite or discrete sampling or both at the same time (WS750 & WS755).
  • Automatic Backflush
    Automatic backflush clears pickup strainer and hose.
  • Low Power
    The composite/discrete water sampler’s 5 AH rechargeable battery will power the sampler for several months or a half hour of continous sampling with both pumps. The unit can also be plugged into an external battery source.
