Continuous Monitoring System for Heavy Metals in Flue Gas

Continuous Monitoring System for Heavy Metals in Flue Gas

AOA 200CEMS flue gas heavy metal online monitoring system is a set of solutions designed by LANScientific for the rapid online analysis of heavy metal pollutants in flue gas. The instrument applies the principle of particulate matter isokinetic sampling and heat tracing extraction technology to automatically concentrate the particles in the smoke and dust on the coil filter membrane after high-precision XRF analysis. It can realize continuous automatic monitoring of the concentration of particulate matter of fixed pollution sources, the concentration of gaseous pollutants and the total amount of pollutants discharged, and send the monitoring data and information to the competent environmental protection department to ensure that the pollutant concentration and total amount of pollutants discharged by pollutant discharging enterprises meet the standards.



In general, the analysis results can be obtained every 15 minutes. The sampling and analysis time can be programmed, and the measurement results can be displayed in real time, making it convenient to view the data on site.

Data transmission

With RS232/485, USB, GPRS, ADSL, Ethernet and other data transmission modes, can realize the remote transmission, monitoring and inspection of operation parameters, status and data.


Professional multiple radiation treatment, the instrument without any radiation leakage.


Automatic quality control, with internal standard elements can automatically check the long-term stability of the system. No personnel on duty, simple operation, simple maintenance, in addition to the filter belt basically no other daily supplies.

Alarm system

Equipped with intelligent alarm system, including: sample temperature abnormal alarm, condenser temperature abnormal alarm, heating temperature abnormal alarm, low flow rate alarm, etc.

Data storage

The instrument and system log function records the operating parameters of the system, and serves as the basis for the accuracy and reliability of system data traceability.
