  Main functions:

  • Accurate measurement of total dissolved gas pressure (O₂, CO₂, N₂) to maintain optimal levels in ponds or aquaculture systems.

  • Continuous real-time monitoring of gas balance in the water.

  • Early detection of dissolved gas anomalies (e.g., CO₂ overpressure) that can cause stress or mortality in fish.

  • Compatibility with RAS systems and other closed aquaculture environments.

  Why monitor gas pressure?

  • Gas overpressure: excess oxygen or carbon dioxide can lead to physiological issues in fish, reducing growth or causing respiratory problems.
