Sigma 1600 Dipper Automatic Liquid Samplers
The dipping action of the Sigma 1600 simulates grab sample collection. Once the liquid in the flow-through chamber is well mixed and turbulent, the dipper arm passes through the full cross section of the flow. Good mixing prevents solids from settling and assures representative and repeatable samples.
The Sigma 1600 Dipper simulates grab sample collection - considered to be the most representative collection method. The large 2-inch inlet provides superior solids handling capability.The sampler can be conveniently located where pumps or gravity can deliver a wastewater stream from each stage of the treatment process. To ensure sample integrity, the sample temperature is tightly controlled at 4°C (39°F) in ambient temperatures up to 49°C (120°F).
