NEPHELOMETRIC TURBIDITY

APPLICATIONS

  • Urban wastewater treatment (inlet/outlet controls)
  • Sanitation network
  • Industrial effluent treatment
  • Surface water monitoring
  • Pumping drinking water

DIGITAL TECHNOLOGY

  • The measure principle is based on IR nephelometry / 850 nm. The sensor can be calibrated with a formazine standard solution
  • The NTU sensor integrates a low-cost optical technology, with a very few maintenance and no consumables.
