1.Introduction to Dust Monitoring System

Dust Monitoring System is used for dust and particle monitoring and measures the particle concentration in the ambient air.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 of total suspended particulate sampler

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 (and) Beta-ray Methods in Ambient Air

2.How Dust Monitoring System Works

The working principle of beta ray absorption method is adopted.C-14 is used as the emission source, which emits constant high-energy electrons.Sample air passes through the injection tube with a constant flow through the cutter, and the particles are trapped on the filter membrane.When the β-ray passes through the filter membrane, the energy decays.The mass of the particulate matter is calculated by measuring the attenuation amount, and the concentration of particulate matter in the ambient air under the actual state is calculated based on the sampling flow rate, sampling time and filter membrane area.This equipment is suitable for online monitoring of particulate matter such as 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) Use the PID constant current algorithm to adapt the pump speed regulation to ensure stable and accurate sampling air flow.

3) Use the five-level calibration method to ensure that the concentration of PM10 can be accurately measured regardless of the height.

4) Use full 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, the minimum period is 3 minutes, and the maximum period is 60 minutes.

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