It's often said that the increase of CO2 in the atmosphere is one of main cause for a global warming phenomenon recently. And it is being finding out that released CO2 in the atmosphere is absorbed by the ocean as well as a forest. it's very important to know the CO2 exchange amount of the atmosphere and the ocean for correct prediction of a fluctuation of the future CO2 concentration of the atmosphere. Our portable corbon dioxyde analyzer achieves highly precise automatic measurement to response this request.
　The CO2 concentration is measured continuously with a high accuracy by non-disperse infrared absorption (NDIR) method. It's possible to measure the CO2 partial pressure in the seawater continuously by using a gas-liquid circulatory equilibriator.
