Abstract: For the measurement of gas, vapor, or aerosol fractions of a measured gas, the fraction to be determined is absorbed in a reaction solution, and a change of resistance from a reaction between the fraction and the reaction solution is determined as the measured variable by an ohmmeter, using electrodes in the reaction solution. The measured gas entering a test container through a sealing unit tight to the reaction solution and passing the medium to be determined, is improved with regard to all-purpose use and convenient measurement. This is done pursuant to the invention by placing the reaction solution in a disposable test container that can be inserted or connected interchangeably to the measuring device which has electrodes. The test container is sealed, at least at one end, with a sealing unit that is permeable to the medium to be determined and impermeable to the reaction solution.

Abstract: Reflector telescope, consisting of a tube (2) disposed in a spherical casing (1) and an outer framework (4) in which the spherical casing (1) is mounted. In known reflector telescopes, the tube is rotatable about its polar and declination axis, requiring two different driving systems. Moreover, access to the spherical casing is variable according to the position of said casing. These disadvantages are avoided by mounting the spherical casing (1) within the outer framework (4) to rotate about a horizontal axis (8), and by mounting said framework on a base to rotate about a vertical axis (50). Fixed and permanent access to the spherical casing (1) and therefore to the tube (2) is thus ensured, and the provision of a driving force for the spherical casing (1) is easily achieved.
