The main components of PM2.5/PM10

air monitor. Inhalable particulate matter in the air. Generally speaking, it is divided into two categories. It can inhale particulate matter PM10 and fine particulate matter PM2.5. Both categories are air pollutants that are more harmful to the human body. The former refers to particles with a particle size of 10 microns or less. The latter refers to particles with a particle size of 2.5 microns or less.

The components of PM10 and PM2.5 are very complex. Including organic matter. Metal elements and their compounds. Sulfate and sulfur dioxide. Nitrate and nitrogen oxides. Silicate and silicon dioxide. Biological aerosols, etc.

PM10 is usually produced in various industrial processes. In addition, in nature. Some ultrafine particles and bacteria will stick together into clusters. Form an aerosol. This is also one of the sources of PM10 in the air.

PM2.5 includes soil dust. sea ​​salt. pollen. spore. germ. These natural products of volcanic ash. There is also power generation. metallurgy. Oil refining. Chemical. Smoke and dust produced in industrial projects such as textiles. And because the fuel burns insufficiently. The droplets left behind. And indoors. Second-hand smoke and hot oil for cooking. A large number of PM2.5 particles will also be formed.

The harm of PM2.5/PM10 to the human body

Some of these substances can cause human body poisoning. And be contaminated by radioactivity. Some can cause acute bronchitis. Symptoms of pulmonary edema and difficulty breathing. Some cause the heart. Damage to the liver and stomach. Even fibrosis of the lungs. Others can cause allergic rhinitis. And lung dysfunction.

In addition to the above-mentioned easily observable phenomena. Stay in an environment with high PM10 and PM2.5 content for a long time. The chance of developing lung cancer will also increase.

This air quality sensor.

In addition, if the air contains higher concentrations of PM10 and PM2.5. It also leads to reduced visibility of the atmosphere. The whole sky looked gray. At the same time, the buildings in this area are also more susceptible to erosion. Those reinforced concrete structures. Or modern buildings that cover a large area of ​​glass facades are okay. Because the corrosion resistance of these buildings is relatively strong. But those ancient buildings. historical buildings. Especially the ancient buildings dominated by wooden structures. The historical buildings are just too much to bear. And the erosion effect of PM2.5 on these buildings. Not worse than acid rain. And the erosion process is more permanent and pervasive. Acid rain will only damage the eaves and exterior walls of the building. PM10 and PM2.5 will even affect the internal space of the building.

Built-in high-quality laser probe. The lowest detectable particle size is greater than 0.3 microns. The minimum measurable concentration can reach 0.1 microgram/m³. The measurement accuracy is high. Low power consumption during operation. The measurement range is wider. Can effectively monitor the air. PM2.5 and PM10 content. It also monitors air VOC. The function of carbon dioxide and temperature and humidity.

The shell part is made of high-density material, which is wear-resistant and anti-falling. At the same time, there are multiple vents on both sides of the body. The heat dissipation effect is excellent. With the bleed fan, it speeds up the air flow from the outside space to the probe. The measurement process is time-consuming Shorter.
