wastewater sampler / automatic / compact / portable
Fits where a full-size sampler won't
Smaller and lighter than our full size 3700 portable, the 3700C uses the same controller. The 3700C will easily pass through an 18-inch diameter or offset manhole.
Bottle choices with the 3700C are more limited than with the full-size model. The bottle options are: 24 polyethylene 500 mL bottles; a single 2.5 gallon (9.5 liter) polyethylene or glass bottle; or a single 2.0 gallon (7.5 liter) ProPak bag with holder. When using the 24-bottle configuration, the 3700C's bottle carrier makes bottle changes fast and easy.
The exclusive non-contacting liquid sensor LD90 gives you automatic compensation for changes in head height, plus automatic suction line rinsing to prevent cross contamination. The 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.
