Description 

 

 

The Global Water WS700R Sampler is designed specifically to meet a wide 

variety of sampling requirements where refrigeration is required; including 

industrial discharge, process control, water and wastewater treatment plants, 

sewers, rivers and streams. 

 

The WS700R Sampler can take individual “time weighted” composite samples, or 

it can be set to take a full-bottle discrete or “Grab” sample.  This is accomplished 

with a Sample Size control having one position being reserved for “Full” bottle.  A 

Sample Interval control sets the time between individual composite samples and 

has a provision for allowing the sampler to be triggered from external sources. 

 

A Start Delay timer can be set to start sampling after a preset time.  This allows 

multiple samplers to be deployed in the field and have them turn on at the same 

time.  The delay can also be used to hold off sampling to let the water source 

flush out debris or other contaminants. 

 

After each sample, the pump will reverse for 15 seconds.  This clears any debris 

from the strainer at the end of the pickup hose and also empties water from the 

hose so the next sample is not contaminated by the previous one. 

 

Inputs are provided for triggering the sampler based on water level, a rain gauge 

sensor or a signal from an external process controller or other monitoring device.  

An output is also available for monitoring when the pump is taking samples, using 

a data logger or similar recording device. 

 

The WS700R Sampler is easily set up near industrial discharges or streams.  It 

can also be suspended in a manhole for sewer flow sampling.  The sampler 

consists of a rugged, rainproof and lockable carrying enclosure.  The enclosure 

houses a peristaltic sampling pump, sample bottle, a control panel, and a 

rechargeable battery.  A battery charger and sample pickup hoses are also 

provided.
