In the rapid development of local economy for many years, various environmental pollution events, such as water, gas and noise, have been appeared in various regions, which seriously affected the quality of life and hindered the sustainable development of the local economy. With the promulgation and implementation of various environmental protection policies and regulations formulated by the state, local governments at all levels have increased their investment in environmental monitoring and emergency monitoring at the same time, and have planned and installed air environmental quality monitoring ground stations in various regions. But the monitoring station can only measure the average air quality in the local area. The portable air quality monitoring equipment is more convenient and quick for the monitoring of the flow environment and the emergency monitoring of the air quality around it, and meets the requirements of the air quality forecast in the field.

The structure is reasonable and can be used as a portable instrument, and can also automatically monitor the inhalable particles on line and on the screen, and display the detection value on the screen. With high sensitivity of imported sensors, the response speed is fast and the resolution is high, and the large screen graphics LCD is used, such as the battery in the equipment after the power supply is broken out. The instrument can be continuously worked for 5 hours, with stable performance, high accuracy, easy operation and easy maintenance. Application area: indoor environment monitoring, office environment monitoring, home environment monitoring
