What is an air quality monitor?

An instrument used to detect air quality can be called an air quality monitor. However, due to the extensive content of air quality, the principles of the instruments used are different. Therefore, in general, a device with the ability to detect several basic air pollutant parameters in the environment is suitable for being called an air quality monitor.We can use air quality monitoring system and air quality monitoring equipment for online monitoring.

Why do we need to test the air quality?

Clean air is composed of 78.06% nitrogen, 20.95% oxygen, 0.93% rare gas, and other gases. These three gases account for about 99.94% of the total air, and the sum of other gases is less than one-thousandth.

A clean atmosphere is one of the necessary conditions for human survival. A person who does not eat or drink water for a short time can still maintain life, but if he does not breathe air for more than 5 minutes, he will die. The human body needs to inhale 10-12 cubic meters of air every day. Therefore, good air quality is a prerequisite for the healthy development of human beings.

Wallmount indoor air quality monitor

This wall-mounted air quality monitor is mainly used to measure the concentration of particulate matter, that is, the concentration of two pollutants PM2.5 and PM10. This is an industrial air quality monitor. The shell design adopts a fully enclosed structure to effectively prevent water and dust, and it can be used normally even in high-concentration industrial environments. This industrial-grade air quality sensor requires higher accuracy and a wider measurement range.

This pm2.5 air quality monitor working principle is developed based on the principle of light scattering: particles and molecules will scatter light under the irradiation of light and absorb part of the light energy at the same time. When a beam of parallel monochromatic light is incident on the particle field to be measured, it is affected by the scattering and absorption around the particle, and the light intensity is attenuated.

This air quality sensor has a high degree of protection and high measurement accuracy. It is widely used in warehouses, libraries, archives, industrial plants, and other places that need PM2.5 concentration monitoring.

The portable air quality monitor is a device used to quickly detect the concentration of particulate matter in the air and certain specific gases. It is usually divided into two types: diffusion and pumping. The diffusion type is detected by the corresponding sensor through the airflow into the inside of the device, and then the reading is displayed. The accuracy of this measurement method is affected by the current airflow rate, and the response is relatively slow. The pumping type uses an external air pump to suck in the current ambient air for detection, so its measurement accuracy is higher and the response is more sensitive.

This handheld air quality monitor adopts an integrated replacement design, is equipped with a suitcase, is convenient to carry, and is used for detection in a variety of different environments. Besides, this handheld air quality monitor can be used to measure the air quality in certain confined spaces or pipes because it can be connected to an external suction pump. It has a variety of models to choose from, and you can select the corresponding monitoring elements according to your requirements, such as PM2.5, PM10, CO, CO2, O3, SO2, NH3, and so on.

This portable air quality monitor working principle is to detect the concentration of pollutants through a built-in electrochemical sensor. It has strong anti-interference ability, high alarm reliability, and long service life, so it is often used in power plants, mines, sewers, and other places where flammable and explosive gas mixtures exist.

Through intelligent and automatic monitoring equipment (PM2.5 sensor, VOCs sensor, sulfur dioxide sensor, ammonia sensor and carbon monoxide sensor), the urban atmospheric environment monitoring solution can collect the ambient air quality data and pollution emission data in real time, and realize the monitoring of the concentration parameters of inhalable particles and other toxic and harmful gases. Through the big data platform for comprehensive monitoring, the management department can view the atmospheric environment data of the monitoring station at any time, and timely grasp the information such as abnormal data, index exceeding standard and fault alarm, so as to realize all-weather and regional air pollution monitoring.
