The WS750 wastewater/stormwater sampler gives you complete control over your wastewater/stormwater sampling process

With the sampler's sample size control, you can take individual time-weighted composite samples or full bottle discrete grab samples. The sampler's sample interval control allows you to 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 triggering event so that your sample better represents the water source.
An automatic 15 second back flush cycle clears any debris from the sampler's strainer and empties the water from the hose so the next sample is not contaminated.

A unique feature of the WS750 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 samplers to take full-bottle discrete (grab) samples, or you can set the 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 samplers are easy to set up in the field.

The samplers rugged rainproof enclosure can be padlocked and/or chained to prevent tampering.
The samplers are enclosed in a relatively small case that can be easily hidden or camouflaged to prevent vandalism. The sampler is lightweight enough that even with a full sample bottle it can be suspended in a manhole for storm drain or sewer sampling.

The WS750 samplers come with two 4.5 litre 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.

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

Overflow Protection
The 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 sampler's peristaltic pumps individually to one of 15 composite sample sizes from 50ml to 2 litres plus a full bottle discrete setting. The 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.
