Abstract
The present invention concerns a device for measuring the partial pressure of gases dissolved in liquids. The device comprises (a) a measurement chamber (14) which is separated by a gas-permeable membrane (11) permeable to the dissolved gas from a sample chamber (10) containing the liquid with the dissolved gas; (b) a light emission source (6) for producing a light beam which passes through the measurement chamber (14) and is of a wavelength absorbed by the dissolved gas; (c) a measurement device (7) for determining the intensity of the light beam leaving the measurement chamber.
