About This

  • Rated 4.6 Stars for Reliable Protection – Our advanced 4-in-1 detector combines high-sensitivity CO and gas leak detection with real-time temperature & humidity monitoring in one plug-in device, eliminating the need for multiple separate units.
  • Fast & Accurate Dual Alarms – Features dual semiconductor & electrochemical sensors that trigger ≥85dB audio and flashing visual alarms the moment CO reaches 50ppm or gas concentration hits 5%LEL, providing an immediate warning for your family.
  • 2-Inch Large Screen for Ultimate Clarity – The extra-large 2.0” P5 display shows all readings clearly from across the room, a significant upgrade over hard-to-read small dots or tiny screens on other detectors.
  • True Plug & Play for Anywhere – Simply plug into any 110V-220V outlet—no wiring or batteries needed. Ideal for kitchen, bedroom, RV, and hotel rooms, giving you peace of mind at home and on the go within seconds.
  • Your Family’s Early Warning System – Don’t wait for a silent threat. Early detection of gas leaks or CO buildup is crucial. Our detector offers 24/7 monitoring with a clear display so you can take action before danger escalates.
