APPLICATION

The Oxygen Analyzer PMA 30 is suitable for the continuous measurement of oxygen in particle-free and dry
sample gases with a maximum dew point of 5 °C.
The features of the anaylzer are safe operation, accuracy and low maintenance.
The measurement is based on the physical principle of the magneto-dynamic oxygen measuring cell and is
one of the most exact quantitative methods of oxygen determination within the range of 0-100 vol% oxygen.
There is a direct flow against the measuring cell which has got a low volume of only 2 ml (small stagnant
volume). Further characteristics are robustness, extremely small drift, fast response time (T
negligible cross sensitivities to other sample gas components.
Fluctuations of the sample gas flow in a range from 10 to 60 Nl/h nitrogen (N
reading which is smaller than 0.1 vol% O
Measurements in flue gases and in inerting plants are some typical applications for the PMA 30 within a great
variety of other measurement tasks.
