AQMS-600 Nitrogen Oxides Analyzer FPI AQMS-600 nitrogen oxides (NO-NO2-NOX) analyzer utilizes chemiluminescence technology indicated by US EPA as federal reference method for monitoring on multiple forms of nitrogen oxides. v Permeation dryer on Ozone generator v Catalytic Ozone scrubber v Independent ranges for NO, NO and NO2 v Compliance with US EPA reference method v Various outputs include ethernet and RS232 v User friendly interface with large screen v Continuous system diagnosis with alarm v Multi-tasking software allows viewing test variables while operating v Temperature and pressure compensation v Internal data logging with 1 min to 365 day multiple averages Nitrogen oxides in ambient are measured indirectly by photometrically measuring the light intensity, resulting from the chemiluminescent reaction of nitric oxide (NO) with ozone (O3). NO is first quantitatively reduced to NO by means of a converter. NO, which commonly exists in ambient air together with NO, passes through the converter unchanged causing a resultant total NO concentration equal to NO + NO2. PMT The optical filter(660nm) attached on PMT provides reliable measurement, and temperature are controlled between 6~8OC with only 0.1OC fluctuation by a thermoelectric cooler, ensure the measurement stability. Ozone generation Permeation dryer are introduced in ozone generation to provide long system durability without any replacement. An catalytic ozone scrubber is standard for maximum safety and pump life before exhaust.
