Membrane Covered Optical Co2 Sensor For Aquaculture - China

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
