    The Nova 322 Portable Paramagnetic Analyzer is designed to measure the oxygen concetration of clean, dry sample gas.  A built-in pressure regulator reduces any positive sample pressure.  A built-in sample pump may be switched on to draw in the sample gas when it is at or slightly below atmospheric pressure.  An external gas scrubber is available if required, to remove any corrosive gases prior to entering the analyzer.

    In operation, the incoming sample gas passes through sample conditioning filters and the flow meter, then into the O2 sensor.  The paramagnetic sensor utillizes a magneto-dynamic measuring cell and powerful selenium cobalt magnet assembly combined with on-board amplification, temperature compensation and barometric pressure compensation.  This cell makes use of the principle that O2 is drawn into a magnetic field, thereby increasing the turning force on a diamagnetic body suspended in the field.  Very few other gases respond this way, making this method specific to O2.  The Model 322 can be used for any O2 measurement between 0-100 as long as the sample gas is clean, dry and non-corrisive.
