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, water and wastewater treatment, waste collection systems, rivers, and streams.

  • Overview

    The 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.

    Samplers Inputs and Outputs

    In addition to taking samples automatically, inputs are provided for triggering the composite/discrete water samplers by PLC devices and other controllers.  These inputs include an external trigger input that accepts a switch closure or pulse input, ideal for flow proportional sampling.  Two separate water sensor inputs can be used for monitoring water level in a rain gauge and at the source using the optional stormwater kit.  A pulse output is also provided for using a data logger, or PLC to record when the samples were taken.  An automatic 15 second backflush cycle clears any debris from the composite/discrete water sampler's strainer and empties the water from the hose so the next composite sample is not contaminated.

    Water Sampler Enclosure

    The composite/discrete water sampler's rugged rainproof enclosure can be padlocked and/or chained to prevent tampering.  The composite/discrete water samplers are enclosed in a case that can be easily hidden or camouflaged to prevent vandalism.  The samplers are lightweight enough that even with a full sample bottle the composite/discrete water samplers can be suspended, from the over-molded handle on top, in a manhole for wastewater or stormwater sampling.  The compact enclosure features heavy duty polyurethane wheels and a retractable extension handle for easy transportation.  The pickup hose comes with quick disconnect fittings which allows it to be disconnected from the composite/discrete water sampler and conveniently stored inside the enclosure when being moved or when not in use.

    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.  An external pulse-type flow meter can control the water sample interval for true flow proportional sampling.

    Remote Water Sampling Notification

    Attach an Autodialer or 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.
