GA-5000DN Ammonia Escape Online Monitoring System

GA-5000DN Ammonia Escape Online Monitoring System (NH3) is based on Tunable Diode Laser Absorption Spectroscopy (TDLAS). It is composed by pretreatment system, gas analysis module and data processing & display. Measured gas passes high-temperature sampling probe for dust removal, tracing pipe for high-temperature transmission, and then enters high-temperature gas analysis module (TDLAS) for analysis and measurement. It effectively solves problems that crystallization of ammonium salt under low temperature blocks flow path; under low temperature, condensate water dissolves NH3 and causes low measurement accuracy; and high dust attenuates optical path in in-situ system and cannot be used for measurement. "Single-line spectrum" absorption technology, avoiding background gas interference; low detection limit and small span drift. Heat tracing above 220℃, avoiding crystallization of ammonium salt or dissolution in condensate water. High automation, less maintenance. Compact structure, convenient for installation.
