Air particle meter monitors airborne particle concentration

In recent years, with the modernization and industrialization development, the pollution of particulate matter in the air is getting more and more serious, how to measure particulate matter in air has become the main topic of environmental protection nowadays, Air particle meter is a kind of instrument used to measure the concentration of particulate matter in the air. It is commonly used in environmental monitoring, industrial production, building construction and other fields, which can help us understand the air quality and take corresponding measures to improve the environment.

Air particle meter working principle

The Air particle meter is based on the principle of light scattering and light absorption. It has a built-in laser and a light scatterer, as well as a particle collector and a light absorber. When airborne particles enter the Air particle meter, the light scatterer scatters the laser beam in all directions, and some of the light is scattered back by the particles and interferes with the light scatterer.

 

The scattered light is then absorbed by the light absorber, which converts the absorbed light into electrical signals. These electrical signals are converted into concentration values by the particle meter and displayed on the screen.

 

The measuring range of the Air particle meter for particulate matter can be adjusted as required. It can measure particles in the diameter range of 0.3 microns to 10 microns, which includes most of the particles that are harmful to human body, such as particulate soot, industrial emissions and so on. Through the monitor, we can understand the concentration of these particles in the air and can assess whether the air quality meets the standard based on the data.

How to use Air particle meter?

When using Air particle meter, we need to pay attention to some things. First of all, it is very important to keep the instrument stable and accurate. Calibrate the instrument regularly to ensure its accuracy and reliability. Secondly, the particle collector and light absorber should be cleaned regularly to ensure their sensitivity and response rate. In addition, it is important to pay attention to the environment in which the instrument is used to avoid the effects of high temperature and high humidity on the instrument.

 

With Air particle meter, we can keep track of the concentration of particles in the air, thus providing a basis for environmental protection, health and safety. Meanwhile, for industries such as building construction and industrial production, Air particle meter can also help companies to implement pollution control measures to meet the requirements of environmental protection.

 

Air particle meter can accurately measure the concentration of airborne particles through the principle of light scattering and light absorption. It has the advantages of simplicity, high accuracy and real-time feedback, which is of great significance in safeguarding people’s health and the sustainable development of the environment. We should make full use of this instrument and work together to improve air quality and create a better living environment.
