Why Monitor Indoor Air Quality Indicators? 1. Formaldehyde: Released from construction boards and furniture; prolonged exposure to elevated levels is carcinogenic and irritates the respiratory tract 2. TVOC: Volatile organic compounds emitted by paints, adhesives, and household chemicals; can trigger dizziness, allergic reactions, and chest tightness 3. CO₂ (Carbon Dioxide): Accumulates in enclosed, crowded spaces, leading to stuffiness and oxygen deprivation; causes drowsiness and diminished concentration 4. Temperature & Humidity: Excessively high humidity fosters mold growth, while excessively low humidity causes dryness that irritates the respiratory tract—both negatively impact comfort and health Product Description: 1.HD Display: The humidity sensor features a backlit LCD screen with a clear, full-color digital interface, allowing for convenient reading. The bright, vibrant display enables you to view real-time updates at a glance 2.Safety Protection: This air monitor accurately monitors harmful gas concentrations in real-time. Equipped with multiple air quality indicator bars, it immediately triggers a voice alert whenever gas levels exceed safe limits, promptly reminding you to open windows for ventilation and thereby effectively eliminating potential safety hazards 3. Minimalist Design: Boasting a sleek and compact form factor, the hydrometer occupies minimal desktop space. Its minimalist aesthetic complements a variety of settings—from modern home interiors and office desks to dormitory bedrooms—serving not only as a humidity monitor but also as a stylish desktop ornament Package Contents: Humidity and Temperature Monitor ×1, USB-C Charging Cable ×1, User Manual ×1
