PROBLEM TO BE SOLVED: To provide a sensor having a substrate for embedding oxygen sensitive dye, while the thus formed sensor is chemically stable to a high temperature, has a high-temperature resistance in the relevant temperature range, and is gas-permeable to a high extent. SOLUTION: The object is achieved in that the substrate consists of a fluoridated silicone polymer. The invention can be applied with particular advantage if the medium is a consumable oil, such as, for instance, sunflower oil, or if a measurement is performed at relatively high temperatures or in chemically aggressive environments. An additional advantageous property is that the substrate is found to adhere well to glass. As a consequence, in practice, the oxygen content can simply be determined in consumable oil products 2 stored in glass, from which in turn a storage life can be derived, and the sensor will not come loose at high temperatures or in chemically aggressive environments.
