Partial oxygen pressure then equates to: ( ) 204.795mbar 100 20.95 ppO 2 986 8.458 = = − ⋅ As we now know the oxygen partial pressure and the total barometric pressure we can work out the volumetric content of oxygen as: 100 20.77% 986 204.8 O 2 %Vol.= ⋅ = Table 1: Maximum water vapour pressure (WVP Max) T (°C)WVP Max (mbar) WVP Max . It is only necessary to adjust the analyzer to the corresponding range level according to the content of trace oxygen in the gas. The output of the flat-plate limiting current oxygen sensor is not the voltage value, but the current value. These detectors continuously operate to confirm low levels (less than 100 ppm) of oxygen. Walsn's OAM oxygen analyzer has a stable secure zirconia sensor, which consists of zirconium dioxide (ZrO₂), and a surface that is coated with a porous platinum electrode layer.
