Turbidity Sensor

This post is also available in: viVietnamese

The Turbidity Sensor is based on the Seapoint Turbidity Meter. The sensor detects light scattered by particles suspended in water. This measurement is known to have a good correlation to the amount of suspended matter in water and can be used to monitor e.g. sediment, algae or particle pollution. The sensor generates an output voltage proportional to the turbidity or suspended solids. The low power consumption makes it ideal for applications where battery drain is a concern. The sensor offset voltage is within 1mV of zero and requires no adjustment across gains. The unique optical design confines the sensing volume to within 5cm of the sensor allowing nearbottom measurements and minimizing errant
reflections in restricted spaces.

Turbidity Sensor can be mounted directly on the top-end plate of the Aanderaa SeaGuard, or on cable connected to SeaGuard or SmartGuard. The sensor output is analog, and output from SeaGuard is in engineering units (FTU).
