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
