Typical applications
Wastewater process
Monitor organic-load changes where a compact immersion probe fits the installation.
Plant inlet and outlet
Combine COD correlation and turbidity trends in one optical measurement point.
Surface-water stations
Use reagent-free optical monitoring in rivers, reservoirs and environmental stations.
Industrial process water
Integrate continuous organic-load and turbidity signals into project controls.
04
Confirm optical path, turbidity and correlation together
The two documented optical paths have different COD and turbidity ranges. Selection must be based on the actual water matrix, reference method, expected ranges, fouling risk and mounting space.
