Application:

Due to the extremely fast response time of the patented M&C magneto-dynamic measuring cell with no stagnant volume as well as the negligible cross sensitivity from other sample gas components, the M&C oxygen-analyser PMA 100 has a wide variety of applications. The analyser is a suitable and reliable instrument for monitoring oxygen concentrations in various gas analytical process control applications including flue gas measurements, inert gas installations, fermentation processes and laboratory process control installations.
