Dissolved oxygen (DO) is one of the most important parameters monitored when evaluating water quality, aquatic biology, and related processes. Until development of optical DO technology, the ability to accurately monitor DO levels over long periods of time was limited.
Electrochemical sensors (Clark, Galvanic) require sample stirring or process flow and are functionally limited by the durability of their membrane and electrode, while galvanic diffusion types offer characteristically slow response.
Key markets and applications where the ppm dissolved oxygen sensor / dissolved oxygen probe is used:
- Municipal and industrial wastewater: Aeration tanks, Aerobic digesters, Plant effluent monitoring (NPDES permit holders) and Anaerobic digesters
- Aquaculture
- Brewing
- Fermentation
- Bio-processing
- Many applications also exist in chemical process, food and dairy, pulp and paper, and other process industries.
