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