TURBILIGHT II® Technology

IR Nephelometry

Measuring light diffused at an angle of 90° from collimated incident beam (projector).
The resulting signal detected by the measuring cell is strictly proportional to the concentration of diffusing particles representative of water turbidity.
Compensation of water colour and diode aging achieved via a measurement at 180°.

TURBISONDE® Technology

INSITU IR Nephelometry

TURBISONDE® operation is based on infra-red (IR) measurement by Nephelometry

The light dispersed at 90 degrees from incident ray by suspended particles is detected by the measuring cell.

The signal yielded is strictly proportional to the concentration of diffusing particles and water turbidity
