Dissolved Oxygen Monitor

Improve performance & reduce maintenance costs

Dissolved Oxygen water quality monitoring is critical for aeration system process control. Optimization of the biological process, whether it’s removal of organic material, nitrification, or nitrification/denitrification, depends on maintaining proper D.O. levels. Controlling air flow to within the optimal range eliminates excess aeration, which translates into significant energy savings.
