WARNING
Measuring gas mixtures with high oxygen concentration
For the measurement of high O
2
concentrations in excess of 25%, it is absolutely necessary 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.
