3.3 Measuring high oxygen concentrations
Note
Measuring high oxygen concentrations
For the measurement of high O
that all parts that come in contact with the sample gas are free of oil and grease and do not
contain any particles that could react with O
We highly recommend you use specially cleaned analyzer modules with the "Cleaned for
O2" option for such measurements.
Note
Measuring high oxygen concentration in hazardous areas
The analysis of gas mixtures with an oxygen content of more than 21% does not form part of
the EU type-examination certificate. Therefore the analysis of these gas mixtures is not
permitted without further consideration.
