Comprehensive indoor air monitoring you can trust 5in1 air quality detector that provides a clear view of your indoor environment by measuring carbon dioxide (CO2), total volatile organic compounds (TVOC), temperature, and humidity. Realtime readings help you identify problems early and take action to improve air quality. Why this matters Prevents unnoticed buildup of CO2 and VOCs that can cause drowsiness, headaches, or discomfort. Tracks temperature and humidity to help you maintain comfort and protect sensitive belongings (electronics, plants, instruments). Visual, immediate feedback enables faster decisions about ventilation, filtration, or HVAC settings. Key features and what makes it stand out Bright 8inch color display: shows all essential data in a readable, realtime format so you always see the current conditions at a glance. Airflowenhancement design: a durable multilayer grid shell promotes steady airflow around the sensors for more accurate measurements and helps prevent overheating during continuous use. Multicolor LED alerts: four distinct LED colors indicate different air quality levels so you can quickly assess safety without reading the screen. Accurate, continuous monitoring: designed for consistent performance to help you act on changes as they occur. Important attributes Function: continuous measurement of CO2, TVOC, temperature, and humidity. Display size: 8inch color screen for clear, realtime data presentation. Construction: multilayer grid shell that improves airflow and operational stability. Performance: realtime monitoring with visual LED alerts for fast situational awareness. Practical applications Home: place in living areas or bedrooms to monitor CO2 and VOC levels, especially when cooking, using cleaning products, or when multiple people share a room. Office or meeting rooms: track air quality to optimize ventilation and maintain alertness and productivity during long meetings. Classrooms and childcare: monitor CO2, temperature, and humidity to support a healthier learning environment and reduce airborne transmission risks. Simple to use and understand The large color display and multicolor LED indicators make operation intuitive for all users. No technical expertise required to read the results and make practical decisions about ventilation or comfort. This device gives clear, realtime insight into core indoor air quality factors so you can maintain a healthier, more comfortable space.
