WS700-WS750 SAMPLER
OVERVIEW
Our new WS700 single-bottle and WS750 two-bottle samplers combine all
the features you need to meet a wide variety of sampling requirements,
including those for storm water, industrial discharge, water and
wastewater treatment, waste collection systems, and rivers and streams.
The WS700/750’s state of the art controller gives you complete control
over your sampling process. With the sample size control, you can take
individual time-weighted composite samples or full-bottle discrete grab
samples. The sample interval control allows you set the time between
individual composite samples or enable the external trigger mode. A
start delay timer allows you to start multiple samplers in the field at
the same time, or to delay drawing a sample after a triggering event so
that your sample better represents the water source An automatic15
second backflush cycle clears any debris from the strainer and empties
the water from the hose so the next sample is not contaminated.
A unique feature of the WS750 model is the ability to set the sampling
mode for each pump and bottle individually. This allows you to take a
time-weighted composite sample and a discrete (grab) sample at the same
time. In the case of two composite samples you can have different size
settings for each pump.
Both the WS700 and WS750 include a trigger input for each pump/bottle to
control sample collection from an external signal like a water level
sensor, rain gauge sensor, external process controller or other
monitoring device. Pulse outputs for each bottle are also provided for
tracking sample collection information via a datalogger or other
monitoring device. See the ordering chart below for a list of compatible
sensors and our WSLO logger option that may be used with the WS700 and
WS750 models.
The WS700 and WS750 samplers are housed in a rugged, weatherproof
enclosure with handles on top and one side for easy portability. Both
units include 15’ of reinforced sampling hose with intake strainer for
each pump, 1 gallon (WS750) or 2.5 gallon (WS700) poly bottle for each
pump, rechargeable gel battery and charger. |
