Influence of barometric pressure The oxygen reading varies in direct proportion to changes of the barometric pressure.
Influence of sample gas flow variation in gas flow between 0-60 Nl/hr air will cause a difference of < 0,1 vol.% O

An external fine filter must always be used at the gas inlet of the analyser.
Depending on the composition of the sample gas, it may be necessary to use a
sample conditioning system. Without precautions, the analyser is only suitable for
measuring of non-hazardous gases or gasmixtures in non-hazardous areas.
