3700 Full-size Portable Water Sampler

Full-size performance and flexibility

The full-featured 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.
