Abstract (en)
[origin: WO9749985A1] The present invention relates to a device for measuring the partial pressure of gases dissolved in liquids. Said device contains (a) a measuring point (15) which is partially separated by a gas-permeable membrane (11) permeable to the gas to be determined; (b) a light emission source (6) for producing a light ray interacting with the liquid in the measuring point (15) and having a wave length which is absorbed by the gas to be determined; and (c) a measuring arrangement (7) for determining the light leaving the measuring point (15). Said device is characterised in that (d) the measuring point (15) is in contact with the interface of a photoconductive element (14), and (e) the light is guided through said element (14) in such a manner that total reflection thereof is reduced at the interface.
