About This

  • 3-in-1 Plug-in Air Safety Monitor – Detects Carbon Monoxide, Temperature & Humidity Simultaneously This all-in-one detector continuously tracks CO levels (0-999 PPM), temperature (-10°C~50°C / 14°F~122°F), and humidity (0%~95% RH) on a clear 2.0-inch screen. It’s your early warning system against invisible CO threats and keeps you informed about your indoor environment.
  • Plug & Play in Seconds with Smart Self-Calibration & Back-Up Battery No tools, wiring, or complex setup. Simply plug into any standard outlet for instant 24/7 monitoring, perfect for any room. Features one-touch self-calibration to adapt to your environment and a built-in 1000mAh battery that ensures uninterrupted safety during power outages. Ideal for homes, apartments, RVs, and offices.
  • Advanced Electrochemical Sensor with 5-Second Rapid Response & High Accuracy Equipped with a professional electrochemical CO sensor, it provides reliable detection with a ±10% error margin. The innovative honeycomb air intake ensures rapid air sampling, delivering a swift alert within 5 seconds when CO is detected.
  • Dual Alert System: ≥85dB Loud Buzzer & Emergency Strobe Light Be alerted your way, day or night. When elevated CO is detected, it triggers a piercing ≥85dB audible alarm (meets UL standards) and a bright flashing strobe light—a critical feature for the hearing impaired or during deep sleep.
  • Clear Display for Instant Status Updates: The easy-to-read screen shows real-time CO levels (e.g., 003 ppm), temperature (e.g., 104°F), and humidity (e.g., 60%) at a glance. Stay informed with accurate, up-to-date environmental data.
