Indoor Air Quality 5-in-1 with HCHO TVOC Sensor, Temperature & Humidity, Rechargeable Battery, LED Display, and CO2The 5-in-1 Quality Monitor Indoor Detector is an advanced device designed to ensure a healthy indoor environment by accurately measuring multiple pollutants and environmental parameters. Crafted with high-quality materials and a durable design, it monitors carbon dioxide (CO₂), formaldehyde (HCHO), TVOC (total volatile organic compounds), temperature, and humidity. Featuring a 9-inch high-definition LED display, the device provides clear, real-time data, including color-coded indicators and alarm alerts that activate when pollutant levels reach unsafe thresholds (e.g., CO₂ levels exceeding 1500ppm). Its multi-sided ventilation design enhances airflow for more precise readings and longer device lifespan. Simple operation is achieved with a one-click switch and an intuitive display, while built-in 4-color LED lights visually indicate indoor air quality status. Powered by a 1200mAh rechargeable lithium battery and supplied with a 5V USB cable, this portable detector is ideal for continuous monitoring in homes, offices, or commercial spaces.
