AM-5302 Ammonia Analyzer

Principle Of AM-5302 Ammonia Analyzer

During operation process, sample gas passes through external reformer first. This type of air pollution analyzer converts NH3,into NO under effect of catalyst. With the original NO in air, it will disply total concentration value of NO. In next cycle period, the analyzer measures NO concentration in air. The difference between the above two values is the concentration of NH3.

Features Of AM-5302 Ammonia Analyzer

• measuring range:0-500ppb or 0-2000ppb(selectable)
• O3 device can adjust O3 generating concentration as required
• Respeciively disply concentration of NH3, HN,NO2 and NOx
• With temperature and pressure compensation
• Timed dark current compensation
• Screen is with color disply and touch control
• Continuous self-inspection with alarm function
• Large-capacity memory; store historical data automatically
• O3 generator with osmotic drying pipe
• Bidirectional RS232 port for remote control
