Feature: 1. Comprehensive Air Analysis: This advanced detector offers a 16-in-1 analysis, covering essential air quality indicators such as CO2, TVOC, formaldehyde (HCHO), and various particulate matters (PM2.5, PM10, PM1.0), ensuring a holistic understanding of your indoor air environment for health-conscious individuals. 2. Real-Time Monitoring & 2.8-Inch TFT Display: The built-in high-resolution 2.8-inch TFT display provides clear, real-time readings of all monitored parameters, allowing users to instantly identify changes in air quality and take necessary actions. The intuitive interface enhances user experience and facilitates quick interpretation of data. 3. Temperature & Humidity Tracking: In addition to air pollutants, the device monitors ambient temperature and humidity levels, crucial for maintaining comfortable living and working spaces. This feature helps regulate indoor climate control systems effectively, preventing mold growth and other humidity-related issues. 4. Durable Material:Made of premium-quality ABS material, this air quality meter is scratch-resistant and impact-resistant, ensuring long-lasting durability even in harsh environments. 5. High Accuracy: One host with 2 sensor. The sub machine is a humidity temperature sensor with very high measurement accuracy, with an error of only ± 1 ℃ and a humidity error of ± 3%. It can be placed in other spaces you want to detect (wireless distance of 30 meters indoors and 60 meters outdoors in open spaces)Scope of use: Home, office, car exhaust, formaldehyde detection inside the car, etc. are not limited.
