    Membrane covered optical CO2 sensor for aquaculture

    Online determination of the dissolved carbon dioxide in water

    /

    The measurement of the dissolved carbon dioxide gas (excluding HCO3 - and CO3 2- ) in the water in fish farms is one of the most important parameters for the success in aquaculture.

    Until now the so called m-value method has been used, which has some disadvantages.

    Apart from the very time-consuming manual analysis, the m-value method is not only influenced by CO2, but also by all the other compounds with influence to the pH-value (e.g.phosphates, silicates, hydrogen carbonate, carbonate).

    Additionally, the m-value method requires sampling, which may lead to errors too.

    On the other hand, a direct reading sensor is required to allow the control of the conditions in the water.

    /

    Main features of the Carbon Dioxide Sensor:

    - submersible direct reading sensor for water and air

    - detects only dissolved CO2 gas

    - no signal interferences to silicate, phosphate, HCO3 - and CO3 2-

    - built-in reference measurement for superior stability
