III. Description
The Global Water WS700 Sampler is designed specifically to meet a wide variety of sampling requirements including industrial discharge, process control, water and wastewater treatment plants, sewers, rivers and streams. The WS700 Sampler can take individual “time weighted” composite samples, or it can be set to take a full-bottle discrete or “Grab” sample. Thisis accomplished with a Sample Size control having one position being reserved for “Full” bottle. A Sample Interval control sets the time between individual composite samples and has a provision for allowing the sampler to be triggered from external sources. A Start Delay timer can be set to start sampling after a preset time. This allows multiple samplers to be deployed in the field and have themturn on at the same time. The delay can also be used to hold off sampling to let the water source flush out debris or other contaminants. After each sample, the pump will reverse for 15 seconds. This clears any debris from the strainer at the end of the pickup hose and also empties water from the hose so the next sample is not contaminated by the previous one. Inputs are provided for triggeringthe sampler based on water level, a rain gauge sensor or a signal from an external process controller or other monitoring device. An output is also available for monitoring when the pump is taking samples, using a data logger or similar recording device. The WS700 Sampler is easily set up near industrial discharges or streams. It can also be suspended in a manhole for sewer flow sampling. Thesampler consists of a rugged, rainproof and lockable carrying enclosure. The enclosure houses a peristaltic sampling pump, sample bottle, a control panel, and a rechargeable battery. A battery charger and sample pickup hoses are also provided.
