Parameters and Functions of Pm Monitor

Ⅰ. Parameters of PM Monitor

Respirable particulate matter content is one of the most important indicators of air quality. Combining years of experience in developing environmental and safety monitoring instruments as well as the latest market demand, the new generation DPM-6000 Atmospheric Particulate Matter Monitor with high accuracy, reliability, stability and economy is launched. It can measure other sizes of PM10, PM2.5 and dust particles, and is widely used in environmental atmospheric monitoring of respirable particulate matter concentration detection.


Air analyzer equipment is quite important nowadays since air pollution is beboming more and more serious.


Ⅱ. Funictions of PM Monitor

1. The design of PM Monitor gas circuit allows the filter paper, radioactive source and detector to remain motionless during concentration and measurement, thus ensuring a low limit of detection. American EPA standard beta-ray attenuation method eliminates the complex operation of TEOM, such as manual replacement of filter paper and weight with. Compared with light scattering method, it has higher measurement accuracy.


2. Aerodynamic simulation based validation of the cutter will provide a variety of accurate particle options: PM1, PM2.5, TSP of PM10.


Low sampling rates are measured by mass flow sensors and corrected with collected ambient temperature and pressure to obtain sampling streams for field conditions.


3. PM monitors from manufacturers of ambient air quality monitoring systems use C14 sources, which have low density, low activity and long half-life periods, making it possible to achieve stable measurements. No special protection is required, safe and reliable, without any radioactive contamination.


4. Flexible paper press structure. Mechanical drive design is simple and reliable, greatly reducing paper breakage and jams and avoiding errors caused by filter paper movement.


5. Duct heating system is used to eliminate the interference of ambient humidity and make the detector suitable for sudden changes in weather.
