Abstract: A detector makes a quantitative determination of the proportion of a component (100) in a flowing medium. The detector has four electrical resistors (2, 3, 4, 5) forming a bridge (20) and in contact with the medium. The resistors are rated for current limited to a few milliamps. Two of the resistors (2, 3) are measuring resistors and two (4, 5) are reference resistors. Preferred Features: The resistors are positioned within but not in electrical contact with the component (101) in the medium (101). The measuring resistors (2, 3) are located in a measuring passage or in a side-branch of a measuring passage. Alternatively, they are located in an externally sealed diffusion chamber filled with a reference medium.
