Adopting a high-precision particulate matter sensor, this Digital Air Quality Monitor with Laser PM2.5 Detector provides you with real-time air pollution levels, temperature and humidity measurements in any surrounding. This helps you determine if it’s safe to stay inside the house or better go somewhere else for the time being.
The monitor’s screen boldly displays the current PM2.5 concentration (particles less than 2.5 micrometers in diameter) which penetrate deeply into the lungs to cause respiratory issues. Thus it is essential for people with existing breathing issues or underlying lung disease. The portable size of the instrument makes it suitable for indoor and outdoor use and compact for travel.
Applicable Scenarios
- Real-time detection of indoor air quality within enclosed spaces
- For outdoor use to detect haze in the air
- Perfect for vehicles while driving to avoid foggy zones
- Also suitable for use in markets, schools, and other public places.
How to Use
- Power on/off: Short press the power button to turn on the device. It starts monitoring PM2.5 after 10s. Long press to turn off the device.

- Short press the ‘set’ button to set the alarm threshold value. Adjust the values using the up and down arrow buttons while the screen is twinkling.
- Finally, short press the button to either save or cancel the setting and return to the main screen.
