Dissolved Oxygen

Dissolved oxygen sensors use an optical luminescence quenching principle to provide precise, maintenance-free measurements without chemical reagents or minimum flow. They are well suited for field use in aquaculture, river monitoring, well water analysis, and wastewater management, delivering reliable oxygen saturation and concentration data wherever water quality must be assessed and protected. Entry-level measurement is also possible with electrochemical sensors.
