Portable Automatic Samplers

Isco 3700 Portable Full-size SamplerFull-size performance and flexibilityThe full-featured 3700 Sampler collects sequential or composite samples based ontime, flow rate, or storm conditions.Accurate, repeatable sample deliveryThe exclusive LD90 Liquid Presence Detectorand patented* pump revolution counting systemdeliver accurate, repeatable sample volumestime after time. This system gives you:? Automatic compensation for changes in head heights? Automatic suction line rinsing to eliminate sample cross contamination.The LD90’s non-contacting design is notaffected by conductivity, viscosity, temperature,or liquid composition. There are no internaltubing connections, so cleaning and tubingreplacement are fast and easy.User-friendly programming for all applicationsBasic and extended programming modes provide you with the versatility for practicallyany collection scheme:? Uniform time intervals? Non-uniform time intervals? Stormwater runoff sampling? Multiple bottle compositing? Split samplingSuperior sample preservationWith thick, foamed-in-place insulation and anexclusive twin-wall design, your samples areprotected. Even in hot or cold temperatures,the 3700 provides the maximum performancein thermal preservation for a portable sampler.Interchangeable controllerThe 3700 Sampler controller components are protected in a tough environmentally sealedenclosure. The enclosure meets NEMA 4X and 6(IP67) requirements for submersible, water-tight, dust-tight, and corrosion resistant operation. To give you added flexibility, the3700 Series controllers are fully interchangeablefor portable or refrigerated sampling.Proven performance and long-term dependabilityare hallmarks of Isco’s 3700 Sampler.Patent #4,415,011Isco Product DataIsco 3700 Portable Full-size Sampler SpecificationsOrdering InformationSuction line and strainer not included; order separately.
