Air Quality Monitor 9-IN-1, CO2, Temperature, Humidity, Formaldehyde TVOC AQI Tester, Professional PM2.5 PM10 PM1.0 Particle Counter for Indoor/Outdoor, Air Quality Meter w/Alarm Thresholds

Smart Detection: This 9-in-1 multifunctional detector comprehensively monitors various air quality parameters: CO2, AQI, PM 1.0, PM 2.5, PM10, TVOC, HCHO, humidity, and temperature, safeguarding your every breath in real-time.
Real-time Monitoring: Unlike ordinary detectors, our device features a multi-color health index and resamples every 1.5 seconds to provide the latest data in real-time. It emits an audible alarm when CO2 levels exceed 1000PPM, ensuring your respiratory health is constantly protected.
Accurate Detection: To address different air quality monitoring needs, the device is equipped with multiple high-precision independent sensors: semiconductor sensors, laser scattering technology, and infrared (NDIR) sensors. Combined with advanced algorithms, this ensures highly accurate and error-free monitoring.
High-definition Display: Featuring a 5.7 large HD display, it shows all values, time, and battery level in real-time. All data is fully displayed on the screen without the need to switch screens. A single button allows you to toggle temperature units. The backlight design ensures all data is clearly visible.
