An Overview
Global Water has developed several automatic water sampler products to meet our clients' needs.  As one of our flagship product areas, we have devoted a great deal of research to developing a group of automatic water samplers that are simple to operate, rugged, and reliable.  We offer three main categories of portable samplers: storm water samplers, portable wastewater samplers, and handheld peristaltic pumps.  These automatic water samplers are discussed further below.

Storm Water Samplers
Global Water offers three different storm water sampler products.  The SS505 Discrete Stormwater Portable Sampler is a smaller, easily movable sampler that can be triggered with a rainfall event and/or by a rise in water level.  It takes a single grab sample of one liter and includes an overflow cutoff switch to prevent spillage.  The SS101 Discrete Stormwater Automatic Water Sampler is a larger version of the SS505 portable samplers.  It is able to take a grab sample of 2.5 liters.  Our third storm water sampler is the SS201 Stormwater Portable Sampler.  This automatic water sampler contains two sample bottles and can be triggered with a rainfall event or by a rise in water level.  The automatic water sampler takes a one gallon discrete sample in one sample bottle and takes a composite sample in the second bottle.  The composite sample size and time between water samples are configurable on the control panel.

Wastewater Samplers
The WS300 Wastewater Sampler is our standard portable wastewater sampler.  The unit takes a composite sample in a 2.5 liter bottle.  The sample size and time between samples are configurable on the control panel.  The automatic water sampler can also be triggered from an external source such as a flow meter.  We also have several cooling options for the samplers including a refrigerated unit, ice bag, and mobile cooler.

Portable Handheld Peristaltic Pumps
Global Water offers two portable handheld samplers.  One is the single speed pump SP100, which includes an internal rechargeable battery.  This unit is reversible and comes with a sampling hose and strainer.  The second version is the variable speed pump SP200, which can sample up to 500 mL of water per minute at four feet of head.  The motor is reversible and can backflush the sample hose at the sample speed.  This unit comes with a battery cable that can connect to a standard external 12 volt battery.
