Wastewater/Stormwater Samplers Product Description
Our new WS750 two-bottle wastewater/stormwater samplers combine all the features you need to meet a wide variety of sampling requirements, including those for stormwater, industrial discharge, water and wastewater treatment, waste collection systems, and rivers and streams.

The WS750 wastewater/stormwater sampler's state of the art controller gives you complete control over your wastewater/stormwater sampling process.  With the wastewater/stormwater sampler's sample size control, you can take individual time-weighted composite samples or full-bottle discrete grab samples.  The wastewater/stormwater sampler's 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 wastewater/stormwater samplers in the field at the same time, or to delay drawing a wastewater/stormwater sample after a triggering event so that your sample better represents the water source.  An automatic15 second backflush cycle clears any debris from the wastewater/stormwater sampler's strainer and empties the water from the hose so the next sample is not contaminated.

A unique feature of the WS750 stormwater/wastewater samplers is the ability to set the sampling mode for each pump and bottle individually.  This allows you to take two individual time-weighted or flow proportional composite samples, or you can set the stormwater/wastewater samplers to take full-bottle discrete (grab) samples, or you can set the stormwater/wastewater samplers to take a full-bottle discrete (grab) sample in one bottle and a time-weighted or flow proportional composite sample in the other.  In the case of two composite samples you can have different size settings for each pump.

The WS750 stormwater/wastewater samplers are easy to set up in the field.  The stormwater/wastewater samplers rugged rainproof enclosure can be padlocked and/or chained to prevent tampering.  The stormwater/wastewater samplers are enclosed in a relatively small case that can be easily hidden or camouflaged to prevent vandalism.  The stormwater/wastewater sampler's is lightweight enough that even with a full sample bottle it can be suspended in a manhole for stormdrain or sewer sampling.

The WS750 wastewater/stormwater samplers come with two 1-gallon polyethylene sample bottles for collecting composite samples, two peristaltic sampling pump, a circuit board controller, and a rechargeable gel cell battery.  Also provided are two sample pickup hoses and a battery charger.  Everything you need is provided for a successful wastewater management or environmental monitoring program.

Low Power
The composite/discrete water sampler's 5 AH rechargeable battery will power the sampler for several months or a half hour of continous sampling with both pumps.

Overflow Protection
The wastewater/stormwater sampler's sample bottles are each equipped with a float switch that automatically turns off the peristaltic sampling pump if the water bottle becomes full.

Sample Size
The user can adjust the wastewater/stormwater sampler's peristaltic pumps individually to one of 15 composite sample sizes from 50ml to 2 liters plus a full bottle discrete setting.  The wastewater/stormwater sampler's peristaltic pumps can be set to a single sample time interval from 5 min. 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 WS750 wastewater/stormwater samplers.  If you already have a flow meter but it has a 4-20mA output, please look at the related products section of the Wastewater/Stormwater Samplers Options & Prices section
