Pro-Oceanus Solu-Blu Dissolved CO2 Probe
The Solu-Blu dissolved CO2 probe can be used for long-term continuous in-situ monitoring to provide reliable free dissolved carbon dioxide data.
- Provides continuous 24/7 CO2 monitoring
- Fully temperature and pressure compensated
- User-input salinity values allow for automatic salinity correction
Solu-Blu Dissolved CO2 Probe
The Solu-Blu series of instruments combine rugged design, ease of use and versatility, all in a single sensor package. The measurement of a gas dissolved in a liquid is facilitated by a semi-permeable membrane that allows gases to transfer from water into a gas head space where the measurement is made.
The Solu-Blu dissolved CO2 probe can be used for long-term continuous in-situ monitoring to provide reliable free dissolved carbon dioxide data. The probe provides a fully temperature and pressure compensated free dissolved CO2 and partial pressure of CO2, and user-input salinity values allow for automatic salinity correction. Flow-through and in-line adapters are also available for simple and effective industrial solutions.
Intensive water re-use systems and well-boats are particularly susceptible to CO2 problems. Increased stocking densities, leaks in aeration pumps, biofilters, source water and more, can lead to elevated CO2 levels. High free dissolved CO2 levels have been associated with formation of mineralized deposits in the kidneys, slowed growth, reduced efficiencies in feed conversion, increased susceptibility to pathogens, and interference with sense of smell leading to erratic swimming. Measurement of dissolved CO2 continuously in RAS with the Solu-Blu dissolved CO2 probe can provide useful and cost-effective feedback control for aeration so that optimal levels of CO2 are consistently maintained.
Elevated CO2 levels alter the delicate balance of the carbonate system in the ocean. These changes make ocean water more corrosive to shellfish shells. Earliest larval stages are particularly sensitive to these changes and often have to divert too much energy to shell building from eating and swimming and this can lead to increased mortality. Intake of ocean water during acidification events has been linked to collapse of oyster seed production at hatcheries. Insitu monitoring is the best method to ensure timely knowledge of changes in carbonate chemistry to allow for protection of shellfish stock.
