1) Note that like ALL zirconia oxygen sensors the Rapidox measures oxygen partial pressure and therefore the oxygen concentration will change with gas pressure. E.g. a 5% oxygen gas will read 5% O₂ at atmospheric pressure but at 3 bar the reading will be 15% O₂

2) Leak rate of the sensor has been measured at 1.6 x 10-7 mbarls-1 through the sensor when hot.
