Air Quality Monitor Indoor, 5-in-1 Portable Real-Time CO2 Detector | Temperature | Hygrometer | HCHO | TVOC | Professional Air Quality Tester for Home, Office, School, Cars, Plants and Pets

• 【Professional 5-in-1 Air Quality Monitor】This professional 5-in-1 air quality monitor accurately measures carbon dioxide (CO2), formaldehyde (HCHO), total volatile organic compounds (TVOC), temperature, and humidity in real time. It helps you keep track of your indoor air quality at a glance, making it ideal for home use.
• 【3-Color Visualization System】This CO2 detector features a high-definition color screen that displays data in real time, ensuring clear readings. It provides a comprehensive assessment of air quality and tracks the average concentration of each gas, enabling data visualization. When air quality exceeds safety thresholds, the screen intelligently changes color, allowing potential air quality risks to be detected immediately—even from a distance.
• 【High Accuracy and Reliability】This home air quality monitor uses high-performance chips and advanced non-dispersive infrared (NDIR) sensor technology to detect carbon dioxide, and is equipped with electrochemical sensors to detect formaldehyde and total volatile organic compounds (TVOC). Compared to standard sensors, it offers higher sensitivity, accuracy, and stability.
• 【Simple Operation】Air Quality Tester: Press and hold the "Power button" for 3 seconds to turn the air quality monitor on or off; and press once to switch temperature settings ℃/℉; press twice to turn the sound on or off; press 3 times to enter the calibration mode; press 4 times to put the screen to sleep(then press once to wake the screen)
• 【Wide Range of Applications】This compact and portable indoor air quality monitor can measure air quality in bedrooms, living rooms, kitchens, offices, cars, schools, hotels, basements, restaurants, campsites, and other environments. It is suitable for use in homes, vehicles, grow rooms, maternity and infant care rooms, and public spaces.
