6-in-1 Indoor Air Quality Monitor

With advanced sensors, the PTH-9A can accurately detect the current levels of CO2 concentration, PM2.5, PM10, AQI, temperature, and humidity.

Three-Stage AQI Indication and Sound Alarm

The air quality detector features three AQI levels - normal (0-50), warning (51-100), and danger (101-500). Should the AQI exceed 100, it will trigger a clear sound alarm.

Automatic CO2 Calibration Function

To easily calibrate the CO2 detector, simultaneously press and hold all three buttons in a well-ventilated area after shutdown, and let it stand for 200 seconds.

Color LED Screen with Time/Date/Year

Beyond air quality monitoring, the color LED screen also displays current time, date, and year. Plus, it can switch between Celsius and Fahrenheit for temperature readings.

Rechargeable and Portable Design

The air quality monitor comes with a 2400mAh rechargeable battery and a convenient hook on the back, perfect for anywhere you need it.
