The 3700 sampler collects sequential or composite samples based on time, flow rate, or storm conditions.
It's a great choice if you don't need the sophisticated parameter monitoring and logging capabilities of our 6700 series.
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. For higher lifts, we recommend our 6700 series.
- Exclusive LD90 Liquid Presence Detector and pump revolution counting system ensure accurate, repeatable sample volumes.
- Basic and extended programming modes for: Uniform time intervals, son-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, and is fully interchangeable between portable and refrigerated samplers.
- Bottle configurations Full size version: 24 x 1 litre PP or 24*350 ml glass - Compact version 24*500 ml PE or 12 * 350 ml.
