1.Introduction to Dust Monitoring System
Dust Monitoring System (β-ray) uses the β-ray method to monitor the concentration of atmospheric particulate matter.The implementation standards of this product are as follows:
HJ/T 374—2007 Technical requirements and detection methods for total suspended particulate matter samplers
HJ/T 93-2013 Technical requirements and detection methods for environmental particulate matter (and) samplers
HJ 1100-2020 Technical Guidelines for Automatic Monitoring of Particulate Matter (and) Beta Ray Method in Ambient Air
2.Working principle of Dust Monitoring System
The working principle of the beta ray absorption method is adopted.C-14 is used as the emission source, which emits constant high-energy electrons.The sample air passes through the cutter and passes through the sampling tube at a constant flow rate, and the particles are trapped on the filter membrane.When beta rays pass through the filter membrane, the energy is attenuated.The mass of the particulate matter is calculated by measuring the attenuation.The concentration of particulate matter in the ambient air under actual conditions is calculated based on the sampling flow rate, sampling time and filter membrane area.This equipment is suitable for online monitoring of particulate matter at construction sites, road construction, factory boundaries, etc.
