In addition, a direct-reading immersed sensor is necessary to allow measurement without alte- ring the temperature and pressure parameters which have a direct influence on this dissolved gas. The CO₂ sensor allows the measurement of the partial pressure of carbon dioxide directly in the water, thanks to a specific membrane permeable only to gases covering an infrared sensor.

Development of a dissolved carbon dioxide sensor based on ...

· The sensor is useful for detecting dissolved carbon dioxide in synthetic seawater in the range from 30 ppm to about 180 ppm. Typical durations of the measuring periods are between 5 and 120 s, depending on the distance between the membrane and the iridium oxide electrode and, of course, on the dissolved carbon dioxide concentration. The thickness of the electrolyte film is a very important ...

Dissolved CO2 Instruments Selection Guide: Types, Features ...

Dissolved CO 2 instruments measure the amount of dissolved carbon dioxide within a liquid sample.. Measurement Principles and Applications. Carbon dioxide, along with oxygen, is one of principal gases dissolved in water sources. In fact, CO 2 is roughly 200 times more soluble than oxygen and can therefore enter liquids much more easily. The surfaces of large bodies of water, such as oceans ...

Dissolved CO2 Sensor HR - Franatech GmbH

The CO2-HR is an in-situ sensor to be deployed underwater. It measures the Carbon Dioxide dissolved in fresh or salt water. The concentration of dissolved CO2 in the water equilibrates with the concentration in the internal detector room of the sensor. Outside water and detector room are separated by a pressure resistant membrane inlet system, which is impermeable to water and ions, but let ...
