All-in-one 6-in-1 indoor air quality detector that measures carbon dioxide (CO2), PM5, HCHO (formaldehyde), TVOC, temperature, and airiness to give a clear, actionable view of your indoor environment. Key benefits — why you need it Identify hidden hazards: Detect elevated CO2, PM5 particles and formaldehyde so you can act before symptoms (headache, irritation, poor sleep) appear. Verify ventilation and comfort: Temperature and airiness readings help you optimize HVAC settings and window/vent use for a healthier space. Quick visual guidance: Four-color LED display and dynamic updates let you see air quality at a glance and respond immediately. Reliable data for decisions: High-precision sensors deliver stable, low-interference readings you can trust for daily use or troubleshooting. What makes this product stand out Six-parameter monitoring in one unit reduces the need for multiple devices and provides a comprehensive picture of indoor air quality. High-precision sensor technology for accurate, stable measurements with minimal influence from external factors. Intuitive four-color LED display that categorizes air quality levels clearly and visually. Real-time S: a dynamic system that shows changes in air quality through visible colour transitions so you can track improvements or deteriorations as they happen. Key functions and performance Measures: CO2, PM5, HCHO (formaldehyde), TVOC, temperature, and airiness. Readability: Four-color LED provides immediate visual feedback; designed for fast interpretation by non-experts. Stability: Sensors engineered for consistent performance and low noise from environmental interference. Practical details and placement Designed for indoor use in living spaces and shared environments. Tabletop/desktop-compatible form factor suitable for placement on counters, desks, or shelves. Simple, user-friendly interface requires no technical setup to interpret color-coded readings. Typical use scenarios Home renovation and new furniture: Monitor HCHO and TVOC after renovations or when bringing new furniture inside to decide when the space is safe to occupy. Workplace and classrooms: Track CO2 and airiness to determine when to increase ventilation, improving focus and reducing drowsiness. Kitchen and living areas: Watch PM5 and TVOC levels during cooking or cleaning to reduce exposure and time high-pollution activities are allowed. What you can expect Compact, easy-to-read monitoring that helps you make immediate, practical choices (open windows, run an exhaust fan, adjust HVAC). Consistent, actionable measurements across six critical air quality indicators, all visible via a simple LED color system and real-time updates. For reliable, all-in-one indoor air monitoring that highlights problems and supports fast, practical responses, this 6-in-1 detector provides the key measurements and clear visual guidance needed to maintain a healthier indoor environment.
