1.6-in-1 multifunctional monitor — six real-time air quality readings for confident indoor air management Key benefits Know what you breathe: continuous, real-time readings of PM2.5, CO2, HCHO, TVOC, temperature, and humidity give a complete picture of indoor air quality. Faster, more accurate response: the scientific air duct and multi-directional ventilation holes ensure full contact with room air, while high-precision sensors and thousands of detection data units improve measurement accuracy and stability. Remote, simple control: connect via Bluetooth to the mobile app to check conditions and trends from anywhere in your home. What it does (functions and performance) Six monitored parameters: PM2.5, CO2, HCHO (formaldehyde), TVOC, temperature, and humidity displayed in real time for actionable information. Ventilation-optimized design: multi-directional ventilation holes and a scientific air duct maximize airflow across the sensing elements to reduce lag and give more representative readings. High-precision sensing: built with high-precision sensors and thousands of detection data units to reduce variability and provide more reliable measurements over time. Intelligent control: Bluetooth connectivity lets you pair the monitor with the mobile app for remote monitoring and easy access to data. Why this product stands out Comprehensive monitoring in a single device — no need for multiple detectors to track particulates, gases, and comfort conditions. Hardware and airflow design that prioritize accurate sampling and repeatable results. App connectivity for convenient, on-demand checks and better decision making about ventilation and air treatment. Practical use scenarios Home with children or elderly: Monitor PM2.5, CO2, temperature, and humidity to keep living rooms and bedrooms safe and comfortable. Post-renovation or new furniture: Track HCHO and TVOC levels to know when it’s safe to occupy spaces after painting or installing new materials. Office and meeting rooms: Watch CO2 and PM2.5 to determine when to increase ventilation, improving concentration and reducing drowsiness. Compatibility and operation Connects to a mobile app via Bluetooth for quick pairing and remote monitoring. (App required for remote access; Bluetooth connectivity provided.) Designed to provide continuous, real-time readings with rapid response thanks to its ventilation hole design and high-precision sensors. What you get A single, multifunctional air quality monitor that measures PM2.5, CO2, HCHO, TVOC, temperature, and humidity with a ventilation-optimized housing and Bluetooth app connectivity for intelligent control and monitoring.
