4-in-1 Indoor Air Quality Monitor, HCHO PM2.5 Detector, Formaldehyde Particulate Matter Temperature Humidity Meter, AQI Reader Tester for Home

Product Description

This is a high-performance air quality monitor primarily used for monitoring PM2.5 and formaldehyde gas concentrations. It also includes temperature and humidity detection. The instrument utilizes high-precision sensors, providing accurate and reliable measurement data with stable performance. The instrument can intelligently connect to a mobile phone and WiFi, allowing for remote monitoring through a mobile device and the recording of historical data. The instrument provides real-time measurements of PM2.5, formaldehyde concentration, and temperature and humidity. This product continuously monitors battery levels and includes a low battery reminder function. Additionally, it features human voice prompts and alarm functions. The instrument is equipped with a 70*70mm color display screen. The formaldehyde detection range is 0-2.999mg/m³, and the PM2.5 detection range is 0-999 μg/m³. The power source is an 1800mAh lithium battery, and the charger is 5VDC-1.5A. The charging interface is Type-C. The main air circulation of the device relies on the back inlet and outlet. When using the device, please ensure that it is upright with no obstruction at the back. The sensor has high detection sensitivity. When conducting detection, please avoid irritating volatile substances to prevent abnormal measurements. This device has overcharge protection function. It can be connected to power for a long time without affecting the battery life. When the concentration of PM2.5 and formaldehyde in the work environment exceeds the standard, the air quality that people breathe deteriorates. This can lead to continuous coughing, chest tightness, and affect overall health. In an environment with excessive formaldehyde concentration, children's health is threatened, resulting in slow growth and a higher risk of developing related illnesses in the long run.
