1. Introduction to Dust Monitoring System

Dust Monitoring System is a device that can continuously and real-time monitor and display the mass concentration of dust particles in the air environment 24 hours a day.

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 test methods for total suspended particulate matter samplers

HJ/T 93-2013 Technical requirements and test methods for environmental particulate matter (and) samplers

HJ 1100-2020 Technical Guidelines for Automatic Monitoring of Particles (and) Beta Rays in Ambient Air

2.Dust Monitoring System Working Principle

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 sample inlet tube at a constant flow rate through the cutter, and the particles are retained on the filter membrane.When the beta ray passes through the filter membrane, the energy decays.The mass of the particles is calculated by measuring the attenuation amount.The concentration of particles in the ambient air under actual conditions is calculated based on the sampling flow, sampling time and filter membrane area.The equipment is suitable for online monitoring of particles in construction sites, road construction, factory boundaries, etc.

3.Dust Monitoring System Functions and Features

1) Use intelligent heating technology to dynamically heat and dehumidify the sampled air to improve measurement accuracy.

2) Using PID constant flow algorithm, the pump speed is adaptively controlled to ensure stable and accurate sampling air flow.

3) Use the five-level calibration method to ensure accurate measurement of PM10 concentration regardless of high or low concentrations.

4) Use full-range zero-point calibration to ensure that each measurement is not affected by the uniformity of the filter paper.

5) The sampling period is continuously adjustable, with a minimum period of 3 minutes and a maximum period of 60 minutes

6) Supports paper saving mode, the filter paper can be recycled according to usage, which can effectively extend the use time of the filter paper.

7) Supports local data query and display, and can query data for any time period.
