Electrochemical Two Electrodes Oxygen Gas Sensors 4O2-GP Toxic gases at TLV levels have no cross-sensitivity effect on oxygen sensors. At very high levels (i.e. percentage levels), high Highly oxidizing gases (e.g. ozone, chlorine) will interfere to the extent of their oxygen equivalence, but most other common gases will not.
