*The PM2.5 Air Quality Monitor refers to a special testing instrument that is used to measure the value of PM2.5 (particulate matter that can enter the lungs) in the air. It is suitable for the measurement of public place environment and atmospheric environment, and can also be used for the evaluation and analysis of the purification efficiency of air purifiers.

*PM2.5 is a particulate matter with a diameter of less than 2.5 microns in aerodynamics, also known as fine particulate matter. Most of the harmful elements and compounds are concentrated in fine particles, and as their particle size decreases, the retention time of fine particles in the atmosphere and the absorption rate in the respiratory system also increase, which has an impact on human health.

*On March 2, 2012, the newly revised ''Ambient Air Quality Standards'' was released, adding PM2.5 monitoring indicators, and PM2.5 changed from popular words to official standards.

*The air quality monitor is based on the principle of constant potential electrolysis sensor to detect polluted gas, light scattering principle to detect dust, and combined with internationally mature electronic technology and network communication technology to develop and develop the latest technology products.

*The instrument is equipped with USB and RS485 data transfer interface, which can transfer the stored data to the computer. The instrument is designed to be powered by a rechargeable lithium battery or AC220V. When AC220V is used for power supply, it also charges the built-in lithium battery. When there is no AC220V power supply, the instrument will automatically start the lithium battery power supply, so that it can be used as a portable instrument. Can also be used as an online instrument
