The particulate matter CEMS online monitoring system can be abbreviated as PM-200 system. This detection equipment is a new type of extraction type low concentration dust measuring instrument recently launched by Beijing environmental protection manufacturers. It is mainly used for continuous online monitoring of high humidity or flue gas containing viscous dust. This instrument is based on the principle of beta ray+light scattering measurement using the extraction dilution sampling method, and can be applied to the measurement of low concentration dust after wet desulfurization and wet dust removal in coal-fired power plants.

Advantages of particle CEMS online monitoring system product:
1. Sampling beta ray method+light scattering measurement, the measurement results are not affected by the shape, color, or particle size of the dust;
2. The product design meets the requirements of the 75/76 standard, and the isokinetic sampling design complies with the requirements of Method 5 of the US EPA;
3. The system is equipped with a calibration film, which automatically calibrates the system every day and periodically calibrates the dilution ratio, ensuring long-term stability of the measurement results;
4. Adopting a dilution sampling probe that is not affected by humidity and has good on-site applicability;
5. Intelligent software design, with self diagnosis and self recovery capabilities, simple operation, and user-friendly interface;
6. Focusing has accumulated rich experience in the CEMS field and has a technical support network that can quickly respond to customer needs in system applications.
