The XYO optical oxygen sensors measure ambient oxygen partial pressure (ppO 2) using the principle of fluorescence quenching by oxygen. An optional pressure sensor allows to also measure barometric pressure (mbar) and to convert the ppO 2 reading to an oxygen concentration (O 2%). The oxygen sensors feature low power consumption, high accuracy and long lifetimes due to the non-depleting sensing principle. Typical applications include oxygen analysers, oxygen concentrators, confined space monitoring, laboratory equipment, agriculture, fire prevention as well as high altitude training.
