The reaction between nitric oxide (NO) and oxygen is used for determination of the oxygen content in the air. The nitrogen dioxide thus produced is dissolved in water. The volume decrease of the gas enables quick and accurate enough determination of the O2 content. The results of 20 measurements give %O2 = 21.04 ± 0.63.
