Reproducibility**
< ±0.01 vol%
Flow rate of sample gas
25-60 Nl/h air
Influence of sample gas flow
Variation in gas flow between 25-60 Nl/h air will cause
a deviation of < 0.1 vol% O

Sample gas inlet pressure
0.6 - 1.6 bar
Sample gas outlet pressure
Recommendation: discharge freely into atmosphere
(requires higher pressure at the analyzer inlet com-
pared to the outlet)
Influence of sample gas pressure
< 1 % of full scale within the range of 0.6 to 1.6 bar abs.
