Abstract
A measuring arrangement for determining the concentration of gases dissolved in a liquid is proposed, which has a simple design and makes possible the use of known gas-measuring apparatus based on color reaction tubes or color reaction capillaries. A preferably flexible tube-like body is provided which is formed of a material that is permeable to the gases to be measured but is impermeable to the liquid. A carrier gas flows on the inside of this body and the body is connected to the gas-measuring apparatus upstream in the direction of the gas flow. The semipermeable material is preferably microporous polytetrafluoroethylene (PTFE).
