ABB 4690 Series Turbidity Systems is a state-of-the-art system for the continuous measurement of turbidity in water. It is based on the nephelometric method, which measures the amount of light scattered by suspended particles in the water sample. The system is highly accurate and reliable

Features of ABB 4690 Series Turbidity Systems:

Flow-through turbidity design

  • fast response to process turbidity changes due to minimal sample residence time

Automatic sensor cleaning

  • reduces maintenance requirements
  • optimizes performance sensitivity

Secondary standards for calibration

  • accurate, repeatable, simple, safe
    • realize significant cost savings by reducing the use of primary standards

Reliable and accurate measurement

  • ultralow back scatter for accurate measurement of low turbidity values
  • • automatic bubble rejection to compensate for erroneous readings due to degassing
