Air quality monitors are essential tools for maintaining a healthy living environment, and ATO offers a range of high-quality devices that can detect various pollutants. These monitors can detect dust (PM2.5, PM1.0, PM10), formaldehyde (HCHO), carbon dioxide (CO2), total volatile organic compounds (TVOC), AQI, temperature, and humidity. They are designed to provide real-time data, allowing users to monitor air quality in homes, offices, cars, or any other indoor space.

The working principle of ATO's air quality monitors involves a combination of high-sensitivity sensors. For instance, formaldehyde sensors use electrochemical principles to detect HCHO levels, while PM2.5 sensors utilize laser scattering technology to measure fine particulate matter. TVOC sensors are typically semiconductor-based, and temperature and humidity sensors provide additional environmental data

ATO's air quality monitors come with a variety of features, including:
- Multifunctional detection of dust, formaldehyde, benzene, and other pollutants.
- Large LCD display for easy reading.
- High-capacity rechargeable battery for long-term operation.
- User-friendly interface with different display options.
- Built-in temperature and humidity sensors.
- Support for time, calendar, and alarm clock functions.

Calibration is crucial for accurate readings, especially for formaldehyde and TVOC sensors. The calibration environment should be free from fragrances, perfumes, paints, and other pollutants. Regular maintenance, including cleaning the sensor surface and replacing filters, is also important to ensure accuracy.


These monitors are suitable for various applications. Ideal for detecting pollutants from new furniture or renovation. Helps maintain a healthy working environment. Monitors air quality during long drives.

Users have praised ATO's air quality monitors for their accuracy, portability, and ease of use. They are particularly appreciated for helping in adjusting ventilation and maintaining a safe air quality level. For example, one user mentioned that the device helped them understand how daily activities affect air quality, making it a valuable tool for maintaining a healthy environment.

ATO's air quality monitors provide a reliable and effective way to monitor indoor air quality, ensuring a healthier environment for you and your loved ones.
