WATER SAMPLER This versatile sampling system allows you to set the sampling mode for each of two pumps and bottles individually. Because it is actually two samplers in one, consisting of two intake tubes, two sampling pumps, and two one-gallon sample bottles, any possibility of cross-contamination between the samples is eliminated. You can obtain two individual time-weighted or flow-proportional composite samples, two full-bottle discrete ( grab) samples, or a full-bottle discrete ( grab) sample in one bottle and a time-weighted or flow-proportional composite sample in the other. When taking two composite samples, you can even adjust sample size settings for each pump. The sampler can be easily set up and installed in any stormwater channel to take and store physical water samples throughout a storm event. Included are a rainproof lockable carrying enclosure, two one-gallon polyethylene sample bottles, two peristaltic sampling pumps, a control panel-enclosed logic timer/ controller, two 15’ reinforced PVC sample pickup hoses with removable debris strainers, a 5 AH rechargeable gel cell battery, and a battery charger.
