HZ80B Particulate matter(PM) online monitor β method

Production Introduction:

The online monitoring system for atmospheric particulate matter is an online monitoring system based on the principle of beta-ray absorption, developed based on many years of experience in the development of ambient air monitors, using low energy C14 as the beta-ray source and photomultiplier tube measurement. The PM10 or PM2.5 particulate matter collected on the filter membrane is automatically and accurately monitored. The system can work continuously online 24 hours a day and is a professional monitoring machine system for particulate matter and noise environmental monitoring and enforcement in urban construction engineers, demolition, traffic roads, industrial parks, and other occasions. Using advanced technologies such as IoT sensing equipment, wireless communication, database, and GIS (Geographic Information System) video, it integrates data collection, transmission, multi-dimensional data display, and application to meet the new form of particulate matter environmental monitoring, pollution prevention, and control and scientific decision-making needs, achieve comprehensive informationzation of dust supervision, provide digital means of supervision for joint enforcement of environmental protection, urban construction, traffic, and other regulatory departments, and meet Joint law enforcement needs.
The system can add the light scattering principle of particulate matter sensors, real-time monitoring of the environment PM2.5, PM10, TSP concentration, and beta-ray principle combined to achieve the accuracy and real-time monitoring of particulate matter Also can monitor the environment temperature and humidity, wind speed and direction, atmospheric pressure, noise (optional) and other parameters. The system uses a dynamic heating system (DHS) to minimize the effect of ambient humidity on the results.
The system has a modular design, with particulate monitoring devices, meteorological monitoring modules, and video monitoring modules. Data transmission and wireless transmission modules, etc. can be configured in any combination. Monitoring data and equipment status can be uploaded to the cloud platform in real-time, with multiple parameters, real-time, intelligent, etc. The system is small, light, and easy to install. Suitable for large-scale grid deployment
