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.
