6 INTRODUCTION
The portable M&C oxygen analyser PMA 10(S) is an non-thermostated instrument which has
been designed for continuous and discontinuous measurement of oxygen concentrations in dry
and particle-free sample gases.
6.1 SERIAL NUMBER
The type plate with the serial number is on the back side of the analyser.
Whenever you call M&C regarding questions or orders for the spares please give us the serial
number of your PMA 10(S).
7 APPLICATION
The PMA 10(S) is based on the magneto dynamic oxygen measuring cell of M&C.
This measuring principle is one of the most accurate methods for oxygen determination within the
range of 0 - 100 Vol.% O2. The robust measuring cell is unique in design and construction.
Due to the extremely fast response time of the M&C magneto-dynamic measuring cell with no
stagnant volume as well as the negligible cross sensitivity from other sample gas components,
the portable M&C oxygen analyser PMA 10(S) has a wide variety of applications. The analyser is
a suitable and reliable instrument for monitoring oxygen concentrations in various gas analytical
control applications including flue gas-, inert gas-, fermentation processes-, food packing machines-, ambient air- and laboratory process control measurements.
It is characterized by safety in operation, robustness, accuracy and the need of low maintenance.
