5-in-1 Carbon Monoxide Detectors，Portable Carbon Monoxide Detectors for Travel | Natural Gas Detector with Temp, Humidity Display | Carbon Monoxide Detector Plug in Wall (1 Pack)

Free Shipping

Main Highlights

5-in-1 Ultimate Safety GuardianThis carbon monoxide detector plug in integrates 5 critical sensors: CO2 detector, natural gas detector, smoke alarm, plus temperature/humidity monitoring. Unlike standard gas detectors for home natural gas, our dual-sensor technology detects smoke particles at 0.1% obs/m sensitivity while tracking CO levels (0-999 PPM) and gas leaks (0-10% LEL), delivering 360° protection for kitchens, bedrooms, and garages.
Instant Triple-Alert Defense SystemWhen threats emerge whether carbon monoxide exceeding 200 PPM, natural gas reaching 5% LEL, or smoke detected the carbon monoxide alarm activates 95dB audible alerts + pulsating red lights + mobile app push notifications. This triple-warning system ensures no danger goes unnoticed, day or night.
HD Smart Display & Travel-Ready PortabilityFeaturing a real-time color LCD that shows hazard levels at a glance, this portable carbon monoxide detector operates as plug-in guardian. Its 2000mAh battery provides 7hr backup power, making it the ultimate travel carbon monoxide detector for RVs, camping tents, and hotel rooms.
Energy-Saving Dual-Power Safety HubAs an eco-friendly plug in carbon monoxide detector, it consumes under 2W on AC power (110V-220V) while maintaining 24/7 vigilance. The co detector plug in seamlessly switches to battery mode during outages, outperforming standard carbon monoxide detectors portable with 2x longer emergency coverage.
Smart Calibration & Multi-Scene ProtectionSimply insert this carbon monoxide detector into any outlet: After 180s auto-calibration, it actively safeguards against CO, natural gas, and fires. Pro Tip: Keep the natural gas detectors higher in the wall for home powered continuously for accurate humidity/temperature readings ideal for baby rooms, offices, and basements.
