    Abstract: 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.

    Abstract: An object is to offer a method that can efficiently measure the oxygen content of both the headspace and fluid within a hermetically sealed container by taking advantage of the characteristics of a fluorescent-type oxygen concentration meter. A container 2 is pierced using a hollow needle 28 with the interior space 28a sealed from the outside and the tip of said hollow needle 28 removed, and the interior space 28a is made continuous with the headspace within the container 2; a probe 11 of a fluorescent oxygen concentration meter 10 is inserted through the hollow needle 28 to the interior of the container 2; the fluorescent material of the probe 11 is positioned in the headspace 3 within the container 2, and the oxygen concentration of the headspace 3 is measured; and the probe 11 is inserted further so that the fluorescent material is submerged in the fluid 4 inside the container 2, and the dissolved oxygen concentration inside the fluid 4 is measured.
