Ebay_Standard DIV FORESTRY SUPPLIERS Product Head--> Global Water Composite/Discrete Water Sampler Description This composite/discrete sampler allows you to control sample size and take either individual, time-weighted composite samples or full-bottle discrete grab samples in a two-gallon sample bottle. You can set the time between individual composite samples or use the external trigger mode for flow-proportional sampling. Use the start delay timer to start multiple samplers in the field at the same time or delay drawing a water sample following a triggering event so that the sample better represents the water source. The automatic 15 second backflush cycle ensures that the next composite sample is not contaminated. Sample size can be adjusted to one of 15 composite sample sizes from 50 ml to 2 liters, and the time interval can be set to one of 15 time settings from 5 minutes to 12 hours. Comes complete with a two-gallon polyethylene sample bottle, a peristaltic sampling pump, a circuit board controller, a sample pickup hose, a rechargeable gel cell battery, and a battery charger. The Stormwater Kit (sold separately) includes a rain sensor, flow sensor, and an auto-drain rain gauge.
