Instruction Manual 760008-A September 2001 Model NGA 2000 TO2 SECTION 1 DESCRIPTION AND SPECIFICATIONS 1-1 The TO2 Analyzer Module uses the coulometric principle of oxygen detection. This technology is based on the fact that oxygen in the sample is reduced by an electrochemical reaction. This reduction occurs at the cathode and results in the generation of hydroxyl ions. These hydroxyl ions migrate to the anode where they are oxidized to reform oxygen.

Quick Start This analyzer module is equipped with a quick start feature which allows the sensor to begin measuring low ppm oxygen faster. This feature can be used when the analyzer is first turned on to decrease the time required for the sensor to reach equilibrium. This function is most effective for gas sample measurements below 100 ppm.
