8 in 1 Air Quality Monitor CO2 Meter Carbon Dioxide Detector CO2 TVOC HCHO PM2.5 PM1.0 PM10 Temperature Humidity Detection with Alarm Function for Home Office Car

8 in 1: Multifunctional air quality detector real-time monitoring of CO2 concentration, TVOC value, HCHO value, PM2.5/PM1.0/PM10 value, temperature and relative humidity in the air. Clear Display: Large digital screen with backlight, clear and easy to read, support alarm function. Multiple display modes are available, you can switch according to your needs. High Accuracy: Using air semiconductor sensor, infrared PM2.5 sensor and electrochemical sensor, plus high-performance chip, detection is more accurate, higher accuracy, and the accuracy can reach 1PPM. Built-in Battery: Equipped with 2000mAh high-capacity rechargeable battery, low power consumption and long endurance, no need to replace the battery frequently. Quick Heat Dissipation: With multiple ventilation holes, which accelerate the convection between the air and the detector, to achieve effective detection and provide a nice heat dissipation effect.
