Water sampler / composite

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.
