The Nova 321 Portable Process Oxygen Analyzer utilizes a reliable, stable oxygen sensor which responds quickly to the oxygen present in a gas sample.  Its life expectancy is between 3 and 4 years.  The sensor is not affected by acidic gases such as carbon dioxide or sulfur dioxide and can operate in a background of hydrogen and many other gases.  It is very easy for the customer to replace and at a resonable price.

A rechargeable 'gel cell' battery provides enough power for the pump and electronics for about 20 hours of continuous operation. The analyzer may still be operated while it is being charged.  A red LED indicates when to recharge the analyzer and a green LED indicates that it is receiving recharging power.  The batter recharger is included with the analyzer.

The detected O2 is displayed on an LCD digital meter that has a switchable backlight for use in dark areas.  The analyzer is supplied with a 12ft. sample hose and either a sample pump or pressure regulator.
