Protect people and property by monitoring ozone and indoor conditions in real time. This air quality monitor gives clear readings, accurate O3 measurement, and configurable alarms so you can respond quickly to changing air quality. Key benefits Immediate, easy-to-read display: 2.8-inch colour LCD (320 x 240 pixels) presents clear, vivid readings so you can assess conditions at a glance. Accurate O3 detection: Advanced electrochemical sensor provides reliable ozone measurements for safety and compliance. Full context for air quality: Built-in temperature and humidity sensors give additional environmental data to help interpret O3 levels. Actionable alerts: Set a custom alarm threshold for O3; the device sounds a warning when levels exceed your set limit so you can take prompt action. Low-maintenance accuracy: Self-calibration ensures consistent, trustworthy readings over time. Convenient power: Charges via micro USB for simple, widely compatible recharging. Low battery warning prevents unexpected shutdowns. What makes this device stand out Precision sensing: Uses electrochemical sensing technology optimized for O3 detection rather than generic particulate or VOC sensors, improving relevance for ozone-specific concerns. Customizable safety limits: Adjustable alarm threshold lets facilities, homeowners, or field teams tailor alerts to regulatory limits, workplace safety standards, or personal tolerance levels. Portable and practical: Compact display and USB charging make it easy to move between rooms, job sites, or vehicles without complex setup. Key specifications Display: 2.8-inch colour LCD Resolution: 320 x 240 pixels Sensors: Electrochemical O3 sensor; temperature and humidity sensors Calibration: Self-calibration function Power: Micro USB charging; low battery warning Typical use scenarios Home safety: Monitor ozone levels near indoor air purifiers, ozone generators, or garages to protect family members sensitive to ozone and ensure indoor air stays within safe limits. Workplace compliance: Use in maintenance areas, chemical handling zones, or manufacturing spaces to detect elevated O3 and trigger worker notifications or ventilation actions. Field testing and inspections: Portable, USB-chargeable monitor for HVAC technicians, environmental inspectors, and facility managers who need on-site ozone readings plus temperature and humidity context. What you’ll gain Faster detection and response to elevated ozone levels Clear, trustworthy readings backed by self-calibration and electrochemical sensing Flexibility to set thresholds that match your safety or regulatory needs Simple charging and low-battery alerts to keep the device ready when you need it This air quality monitor combines a high-resolution colour display, reliable electrochemical O3 measurement, temperature and humidity context, customizable alarms, self-calibration, and convenient micro USB charging for practical, dependable ozone monitoring.
