Know Your Air: Upgraded indoor air monitor with built-in electrochemical sensors for formaldehyde (HCHO) and total VOCs (TVOC). It provides accurate readings of common indoor pollutants. 2021 Design: Features an LCD color display and delivers stable average values. Real-time measurements can drift over time, so the device reports 30-minute and 60-minute averages for reliable trends. Compact and Portable: Lightweight and easy to place on a desk or move between rooms. Suitable for homes, offices, workplaces, government facilities, schools, and vehicles. Detects air quality issues and alerts you to problems. Indoor Use Only: Best used as a stationary unit. Rely on 30-minute and 60-minute averages and general environmental readings rather than long-term real-time swings. Use Scenarios: - During home renovation or when new furniture is installed to monitor HCHO and VOC levels and take action - In offices or classrooms to maintain healthy air and guide ventilation decisions - In a vehicle or fleet setting to assess cabin air quality and protect occupants
