- An online turbidity meter can estimate COD only after establishing and validating a correlation for the specific stream. Changes in wastewater composition can change that relationship.

Match the instrument to the wastewater stream
Consider a retractable wastewater turbidity meter, the Maselli UR62 drain refractometer, or a Real Tech BOD/COD field meter. These instruments measure different optical properties. Select and validate the approach against representative samples and reference measurements.
