WS700R Refrigerated Sampler
  • Ideal for refrigerated wastewater, industrial and environmental sampling
  • Simple to operate – no programming required
  • Rugged construction for harsh environments
  • Meets federal, state and local wastewater regulations
  • Timed and external flow pulsed composite samples
  • Adjustable and repeatable sample volume
  • Peristaltic pump prevents sample contamination


The WS700R Refrigerated Wastewater Sampler's state of the art water sampler controller gives you complete control over your water sampling process.  With the water sample size control, you can take individual time-weighted composite samples or full-bottle discrete grab samples in
a 2 gallon sample bottle.  The water sample interval control allows you set the time between individual refrigerated composite samples or enable the external trigger mode for flow proportional sampling. A start delay timer allows you to start multiple WS700Rs 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.  An automatic 15 second backflush cycle clears any debris from the strainer and empties the water from the hose so the next refrigerated composite sample is not contaminated.

Overflow Protection
The WS700R's sample bottle is equipped with a float switch that automatically turns off the peristaltic sampling pump if the water bottle becomes full.  Flow Proportional Sampling an external pulse type flow meter can control sample interval for true flow proportional water sampling.  Global Water's Open Channel Flow Monitor has a flow proportional output signal for triggering WS700Rs.
