ISCO 3700 Sequential / Composite Sampler Rental
- Exclusive LD90 Liquid Presence Detector and pump revolution counting system ensure accurate, repeatable sample volumes.
- Basic and extended programming modes for uniform and non-uniform time intervals, stormwater runoff sampling, multiple bottle compositing, split sampling .
- Thick, foamed-in-place insulation and twin-wall design provide maximum performance in sample preservation.
- 3700 Controller is housed in a NEMA 4X and 6 (IP67) environmentally sealed enclosure.
The exclusive LD90 gives you automatic compensation for changes in head height, plus automatic suction line rinsing to prevent cross contamination. The non-contacting liquid sensor is not affected by conductivity, viscosity, temperature, or liquid composition. There are no internal tubing connections, so cleaning and tubing replacement are fast and easy. The 3700 pump outperforms most competing samplers and maintains the EPA-recommended 2 ft/second line velocity at head heights up to 16 feet, with 1/4-inch suction line.
