Handheld Air Quality Index (AQI) Monitor

The handheld air quality index (AQI) detector collects real-time concentrations of pollutants such as PM2.5 and formaldehyde in the air through built-in sensors, and calculates a comprehensive index by combining temperature and humidity data. It is used for on-site rapid assessment of indoor and outdoor air conditions, commonly applied in scenarios such as environmental monitoring and renovation acceptance inspections.
Selection
When selecting, focus on matching the detection items with requirements, verify sensor accuracy and calibration cycles, check the device's response speed and data recording capabilities, confirm the user-friendliness of the operation interface, understand battery life and maintenance costs, and consider adaptability to real-world usage scenarios.
