How to choose beta ray dust detector

At present, particulate matter has become the primary pollutant of urban air pollution in China, and the number of particulate pollutants from industrial smoke and dust is decreasing year by year, while the proportion of particulate matter from dust in the total particle pollutants is increasing year by year, and has become an important factor causing urban particulate matter pollution.

The main sources of urban dust pollution are natural dust caused by unfavorable climatic conditions, construction dust caused by extensive construction, stacked dust flying in the wind and road dust which has a great impact on pedestrians. Among them, with the rapid development of China's urbanization construction and the increase of construction intensity, the proportion of unorganized dust in construction projects in many urban areas continues to rise, which was once low and often concentrated in densely populated urban areas, and has become the main source of urban dust pollution, and its impact on air quality has become increasingly concerned.

Functions and Features:
1) Use intelligent heating technology to dynamically heat and dehumidify the sampled air to improve measurement accuracy.
2) PID constant current algorithm is used to adjust pump speed adaptively to ensure stable and accurate sampling air flow.
3) Use the five-level calibration method to ensure that the PM10 concentration can be accurately measured regardless of its level.
4) Use full zero calibration to ensure that each measurement is not affected by the uniformity of filter paper.
5) The sampling period is continuously adjustable, the minimum period is 3 minutes, the maximum period is 60 minutes
6) Support paper saving mode, filter paper can be recycled according to the use of conditions, can effectively extend the use of filter paper time.
7) Support local data query display, can query any time period data.
8) Support wired network communication and 4G wireless communication
9) Support remote system upgrade and parameter setting
10) Support local data storage, data storage duration up to 365 days.
