The sensor has a linear calibration and is resistant to aliphatic hydrocarbons, in particular aviation fuel. A low cost and easy-to-implement method for calibrating the sensor was proposed. Temperature dependence of the oxygen mass transfer coefficient kL was measured for aviation fuel TS-1 (Russian equivalent of Jet A-1) in the temperature range of 10 to 40 °C as a demonstration of the sensor capabilities. The dependence found obeys the Arrhenius equation with the parameters EA = 21.7 ± 1.5 kJ/mol, kL0 = 1080 ± 90 m·h-1. The resistance to mechanical action is one of the important advantages over the sensor made of a sol-gel matrix with a protective coating. Damage to some part of the surface does not change the properties of the entire sensor, since the composite material contains a large number of isolated particles with a dye. %U https://www.ije.ir/article_88193_85d32fd72735653ecef5a2f38a112037.pdf
