1. Multi-function Air Quality Detector: Monitors multiple air pollutants including HCHO, TVOC, PM2.5, PM10, temperature, humidity, CO and CO2, ensuring comprehensive indoor air quality protection. 2. Sensor Technology: Utilizes advanced semiconductor/infrared detection technology and MEMS detection technology to data accuracy and reliability, allowing you to monitor air quality changes in real-time. 3. Long-lasting Battery: Built-in1200mAh lithium battery, charging for about 4 hours can provide 300-360 minutes of continuous operation, even under high power consumption from multiple sensors. 4. User-friendly Design: Features a 2.8-inch TFT color screen with clear digital display for a comfortable visual experience; also for easy monitoring of air quality changes. 5. It features with multiple ventilation holes to facilitate real-time air circulation and convection. This design ensures that the sensor is in fullcontact with the air, enhancing its sensitivity and enabling accurate detection of small particle content.
