Description：
The nitrogen oxide monitor adopts the pump suction sampling mode, which can directly extract air from the atmosphere. The gas entering into the instrument successively passes through the gas treatment circuit such as the steam trap, and finally enters the nitrogen and oxygen gas analyzer. Through advanced detection technology, the nitrogen and oxygen concentration in the gas can be measured. The NOx on-line monitoring system is suitable for gas detection and analysis in the situation of low dust, high temperature and high humidity.
Features：
The main principle is: the sampling unit collects the flue gas or the measured gas on site, the pretreatment unit cools the gas, dehumidifies, filters the dust, and keeps the temperature and humidity of the measured gas within a certain range, the gas detection unit detects and analyzes the delivered gas, displays the measured gas concentration in real time on the display screen, and transmits the data signal to PLC or computer The terminal can also be transmitted to local environmental protection bureau or cloud server through wireless GPRS (DTU) or network, and users can read data from the server to realize global network monitoring and analysis. The whole process is automatic without human intervention.
(1)The nitrogen oxide monitoring system adopts pump-suction sampling, with a large monitoring range, short response recovery time and wide measurement range;
(2)A variety of networking interfaces: 2G, 4G, NB-IoT, RS485, etc., directly upload to the cloud platform without the data acquisition instrument;
(3)Accurately measure data and monitor multiple pollutant gases simultaneously, with high time/space resolution and detection sensitivity;
(4)Intelligent temperature and zero compensation algorithm;
Seven-inch LCD screen, high-definition data display, easy to read.
Application field：
NOx online monitoring system is mainly used in gas analysis industry. Main detection occasions: gas boiler exhaust gas monitoring, pollution source online monitoring, flue gas emission, desulfurization and denitrification, boiler exhaust gas, sewage pipe gas detection and analysis, high temperature and high humidity gas detection and analysis, etc.
