Features & Applications:
This Global Water automatic stormwater / wastewater sampler allows you to take a wide variety of samples, from stormwater and wastewater to rivers and streams-even industrial discharge and water treatment. The sample size control lets you take individual time-weighted composite samples or full-bottle discrete grab samples. There’s even a start delay timer so you can start multiple samplers in the field at the same time. An automatic 15-second backflush cycle clears any debris from the strainer and empties the water from the hose so that your next sample isn’t contaminated. Sample pump has a flow rate of 1Lpm. at a 4' head. Maximum lift is about 20'. Pickup hose is 15'L nylon-reinforced PVC tubing with a stainless steel strainer and a 1/4" I.D. Unit measures 22"H x 17"W x 9"D.
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. Comes 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.
