The Compact version of the 3700 automatic water sampler can easily be passed through an 18 inch or offset manhole. The bottle choices with the 3700C are more limited than with the full size portable model. Available options are: 24 polyethylene 500ml bottles; a single 2.5 gallon (9.5 litre) polyethylene or glass bottle; or a single 2.0 gallon (7.5 litre) ProPak bag with holder. The 3700C's bottle carrier makes bottle changes fast and easy, when using the 24 bottle configuration.
The LD90 gives automatic compensation for changes in head height, plus automatic suction line rinsing to prevent cross contamination. The LD90 features anon-contacting liquid sensor which is not affected by temperature, viscosity, conductivity or liquid composition. Cleaning and tubing replacement is fast and easy, as there are no internal tubing connections. The 3700 automatic sampler pump outperforms most competing samplers and maintains the EPA-recommended 2ft/second line velocity at head heights up to 16 feet, with ? inch suction line. The 6700 series is recommended for higher lifts.
