4690 Series Turbidity Systems
EPA- and ISO-compliant turbidity measurement
The measurement of turbidity is a critical measurement in drinking water as it is used to indicate water quality and filtration effectiveness (for example, whether disease-causing organisms are present). ABB's 4690 range of turbidity systems have been designed specifically for the measurement of turbidity throughout the potable water treatment process.
