Characteristics: Portable air quality monitor adopts air semiconductor and infrared sensor. It supports mobile app connection via BT and you can view the data within 60 days. Large digital LCD display and real-time monitoring are very suitable for families, offices, schools, warehouses, agricultural planting, etc. Features: Nine in: multi-function air quality detector displays real-time time and date, and monitors CO2 concentration, HCHO value, value TVOC, PM2.5/PM1.0/PM10 value, air temperature and relative humidity. Clear display: large digital screen with backlight, clear and legible, supporting alarm function. Various display modes are available and can be switched as needed. High precision: Using air semiconductor and infrared sensor, combined with high performance chip, the detection is more accurate, the precision is higher, and the precision can reach 1PPM. Application control: Support mobile APP connection via BT, you can read up to 1440 groups of data within 60 days, which is compatible with iOS and Andoid systems. Fast heating dissipation: has multiple ventilation holes to accelerate the convection between the air and the detector to achieve effective detection and ensure good heat dissipation effect. Built-in battery: equipped with 2000mAh large capacity battery, low power consumption, long battery life, no need to replace the battery frequently. Widely used: portable, suitable for home, office, school, warehouse, agricultural planting etc. automatic monitoring without calibration at startup.
