CO₂/CO/HCHO/TVOC/AQI Air Quality Detector with LCD Screen, Integrated Thermometer & Hygrometer – Pro Model

Multiple Detectable Gases: Knowing the air quality where you live is essential for everyone. The enhanced Indoor Air Quality Monitor incorporates a DART electrochemical sensor to accurately detect carbon dioxide (CO2), formaldehyde (HCHO), and volatile organic compounds (TVOCs) in the air. These measurements include the detection of toluene, harmful chemicals, and air pollutants such as carbon dioxide. High-Definition LED Digital Display: After turning on and allowing the air monitor to warm up for two minutes, the LED display clearly shows five indicators for CO, CO2, HCHO, TVOCs, and AIQ in real time. The monitor's battery status is indicated by three colors: green, orange, and red. Green indicates sufficient charge. Orange means the battery is low. Red indicates a low battery (please recharge it promptly). Ease of use: The air quality monitor has three easy-to-use buttons. ON/OFF: Press and hold for 3 seconds to turn the device on or off. BACK ON: Press and hold for 3 seconds to reset the instrument's calibration. RESET: Press and hold the button for 3 seconds to clear the data and perform a new reading. Portable: This air quality measuring device is compact and easy to carry. Dimensions: 122 x 63 x 28 cm. The base angle of the instrument is 15 degrees. This air quality tester is ideal for living rooms, bedrooms, cars, offices, schools, and other indoor environments, especially those with babies, children, the elderly, and pregnant women. NOTE: This air quality monitor is designed for indoor use. Close doors and windows before testing. We recommend using the device as a stationary unit and paying attention to long-term averages (at least 60 minutes) and an overall indication of environmental quality. Ensure the reading is clear and complete. It will be displayed after 10 minutes of power-up.
