Application range of NOx/O ₂ / NH ₃ detector

NOx/O₂/NH₃ detectors are widely used in the flue gas emission monitoring in electric power, glass, steel, chemical engineering,

kiln, environmental monitoring, distributed energy, research center, experimental platform and other fields. 

The detector consists of NOx online detector and ammonia escape analyzer. It can perform real-time detection of NOx, and

convert according to the actual oxygen content. At the same time, it can also detect the escape amount of NH3 in the exhaust

gas. The detector adopts the extraction method, which separates the sampling system from the analysis system, so the analysis

system is in a space with relatively good environment.

The collected data can be converted into 4-20 mA output. It can be extended to RS485 output. It can also be extended to touch

screen. At the same time, it has internet of things remote transfer function, which can transmit the field monitoring data to all

over the world through GPRS/wifi. It is convenient for after-sales maintenance and monitoring the actual usage.

As the flue gas discharged by industrial enterprises often contains dust, particulate matter, ammonium sulfate, ammonium

hydrogen sulfate and other sulfide, which will cause blocking, short circuit or poisoning to the probes, the flue gas need to be

filtered.  In order to prevent water vapor condensation and soot blocking, this equipment is equipped with heating belts and

ceramic filters to effectively filter impurities.
