The Global Water WS705 composite/discrete water sampler’s state of the art water sampler controller gives you complete control over your water sampling process. With the composite/discrete water sampler’s sample size control, you can take individual time-weighted composite samples or full-bottle discrete grab samples in a 2.5 gallon sample bottle. The composite/discrete water sampler’s 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.
The Global Water 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, water and wastewater treatment, waste collection systems, rivers, and streams.
Product Features
Sampler Power
The composite/discrete water sampler’s 5 AH rechargeable battery will power the sampler for several months or several sampling events. The sealed gel-cell battery and BC100 smart charge controller are contained in a separate battery box inside the composite/discrete water sampler’s main enclosure to isolate and protect electrical connections. The included smart charger prevents overcharging and greatly extends battery life over other charging methods.
Overflow Protection
The composite/discrete water sampler’s sample bottle is equipped with a float switch that automatically turns off the peristaltic sampling pump if the water bottle becomes full.
Water Sample Size
The user can adjust the composite/discrete water sampler’s sample size to one of 15 composite sample sizes from 50 ml to 2 liters plus a full bottle discrete setting and the composite/discrete water sampler’s sample interval to one of 15 time settings from 5 minutes to 12 hours plus an external trigger mode setting for flow proportional sampling.
Flow Proportional Sampling
An external pulse-type flow meter can control the water sample interval for true flow proportional sampling. Global Water’s Open Channel Flow Monitor has a flow-proportional output signal for triggering the WS705 composite/discrete water samplers.
Remote Water Sampling Notification
Attach the AD200 Autodialer or CVD-2000P Cellular Autodialer to your composite/discrete water sampler to add remote sample notification. This accessory will save you travel time by ensuring that you always know when your composite/discrete water samplers have taken a sample at your monitoring sites.
What’s Included
The WS705 composite/discrete water samplers come with a 2-gallon polyethylene sample bottle for collecting composite samples, a peristaltic sampling pump, a circuit board controller, and a rechargeable gel cell battery. Also provided is a sample pickup hose and a battery charger. Everything you need is provided for a successful wastewater management or environmental monitoring program.
