Our new WS700 single-bottle and WS750 two-bottle samplers combine all the features you need to meet a wide variety of sampling requirements, including those for storm water, industrial discharge, water and wastewater treatment, waste collection systems, and rivers and streams.

The WS700/750’s state of the art controller gives you complete control over your sampling process. With the sample size control, you can take individual time-weighted composite samples or full-bottle discrete grab samples. The 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 samplers in the field at the same time, or to delay drawing a sample after a triggering event so that your sample better represents the water source An automatic15 second backflush cycle clears any debris from the strainer and empties the water from the hose so the next sample is not contaminated.

A unique feature of the WS750 model is the ability to set the sampling mode for each pump and bottle individually. This allows you to take a time-weighted composite sample and a discrete (grab) sample at the same time. In the case of two composite samples you can have different size settings for each pump.

Both the WS700 and WS750 include a trigger input for each pump/bottle to control sample collection from an external signal like a water level sensor, rain gauge sensor, external process controller or other monitoring device. Pulse outputs for each bottle are also provided for tracking sample collection information via a datalogger or other monitoring device. See the ordering chart below for a list of compatible sensors and our WSLO logger option that may be used with the WS700 and WS750 models.

The WS700 and WS750 samplers are housed in a rugged, weatherproof enclosure with handles on top and one side for easy portability. Both units include 15’ of reinforced sampling hose with intake strainer for each pump, 1 gallon (WS750) or 2.5 gallon (WS700) poly bottle for each pump, rechargeable gel battery and charger.
