For very precise measures and low Turbidity values, as required by most drinking water application, we suggest to install the probe in the flow cell. The cell is equipped with a flow regulator to avoid air bubbles, which can come from grab samples under pressure. Cleaning the cell is extremely simple, and it can also be used for calibrations with Formazine. Sensors can also be installed in pipes, and special adapters and Tee assembly.
