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 automatic 15 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 minutes 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. 

Remote Water Sampling Notification

Attach an autodialer or cellular autodialer to your sampler to add remote sample notification.  This accessory will save you travel time by ensuring that you always know when your water samplers have taken a sample at your monitoring sites.
