Turbidity Sensor

The Aanderaa Turbidity sensors detects infra-red 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.


  • Optically confined sensing volume
  • Insensitive to ambient light when under water
  • Linear output over more than 5 decades
  • 4 selectable ranges
  • Optic feedback compensated for temperature drift and aging of optical components
  • Very low offset voltage does not require adjustment
  • Very low power requirements
  • Maximum depth range 6000 meter


  • Pollution monitoring
  • Water and waste water quality
  • Sediment transport
  • Ocean profiling
  • River and stream monitoring
