Medium Affected Materials

3.2.1.2 Applications With Corrosive Or Solvent ComponentsSpecial paramagnetic oxygen sensors are available to measure gases, containing cor-rosive or solvent components. See below tables for further information on approved solvents, and medium affected materials.The table below shows, how accompanying gases interfere the paramagnetical oxygen measurement. If the concentration of such gases is already given at time of enquiry, this interference may be taken into account during factory startup and thus minimized (option).
