【Five-in-One Real-Time Monitoring】: Carbon monoxide, oxygen concentration, barometric pressure, temperature, and humidity—delivering actionable real-time data for indoor spaces and outdoor adventures. Perfect for households, outdoor enthusiasts, and anyone prioritizing air safety and comfort.
【Newly Upgraded High-Precision Sensor】: Equipped with a professional electrochemical CO/O₂ sensor, featuring CO measurement accuracy of ±10ppm or ±5%, O₂ resolution of 0.1% vol, and barometric pressure measurement accuracy of ±1hPa (950-1050hPa). The sensor updates data every 2 seconds, providing real-time insights.
【Triple Visual and Audible Alarms】: The smart safety system features clear color-coded indicator lights & high-volume alarms: ✅ 0-50 PPM CO: Green light (safe); ✅ 51-200 PPM CO: Yellow light & audible alarm; ✅ 201-500 PPM CO: Red light & continuous alarm (press button to pause for 5 minutes, automatically resumes to prevent missed alerts). When oxygen concentration falls below 19.5% or exceeds 23.5%, both audible alarm and icon flashing are triggered simultaneously—critical for preventing carbon monoxide poisoning and oxygen deprivation in enclosed/high-altitude spaces.
【1500mAh Rechargeable Battery & Type-C Fast Charging】: High-capacity rechargeable lithium battery delivers 72 hours of standby time (or extended usage in power-saving mode). Supports Type-C cable DC 5V/2A fast charging & low battery alert (5-minute beep cycle when ≤5% charge) to prevent unexpected shutdowns. Smart auto-sleep mode (after 20 seconds of inactivity) conserves power while maintaining responsiveness—ideal for off-grid camping or extended travel.
【Portable Metal Housing Design】: 71×33 mm (diameter × thickness), 220g metal housing body, includes hanging hook—easily clips onto backpacks, tent zippers, or keychains; metal housing ensures long-lasting durability, efficient heat dissipation, and a premium feel.
【What You Get】: GZAIR PT08, Charging Cable, User Manual, Carabiner Clip, GZAIR 12-month Warranty & 24/7 Customer Support Access via Email and Phone.
