For atmospheric pressure sampling, connect a pump and flow control valve downstream from the analyzer and draw (rather than push) the sample through the instrument. IMPORTANT: IF A PRESSURE REGULATOR IS USED, IT MUST HAVE A METALLIC DIAPHRAGM. REGULATORS WITH ORGANIC OR PLASTIC DIAPHRAGMS ARE PERMEABLE TO OXYGEN AND, IF USED IN THE SAMPLING SYSTEM, WILL LEAD TO HIGH OXYGEN READINGS. The instrument is shipped with a g
