Product description





What types of gases can our 4-in-1 Natural Gas & Carbon Monoxide Detector detect?
It supports carbon monoxide, methane, LPG, LNG, Fuel, natural gas, fuel, ethane, butane, alcohol, coal gas, gasoline, toluene, kerosene, sewer gas, and other flammable gases.
Why do I need to remove the protective film before using the detector?
Tearing off the protective film can ensure that the numerical display is clearer. There will inevitably be impacts during transportation, which will cause scratches on the protective film (not second-hand goods).
Why Choose 4-in-1 Natural Gas & Carbon Monoxide Detector?
The 4-in-1 detector simultaneously detects natural gas and carbon monoxide, while also displaying temperature and humidity. This comprehensive functionality ensures the health and safety of you and your family, surpassing single-function detectors.
Why does the detector need to warm up for 180 seconds?
Warming up ensures detector’s working properly and accurately.
What should you do when the detector alarms?
Confirm the gas leak source, avoid electrical devices and flames, and ventilate the area. If it’s a natural gas leak, shut off the gas. For a high carbon monoxide alarm, evacuate immediately and call emergency services.
【2 Packs 4-IN-1 Detection System】This enhanced 4-in-1 Natural Gas Leak Detector & Carbon Monoxide Detector combines natural gas detection, carbon monoxide sensing, temperature monitoring, and humidity measurement. Featuring dual-sensor technology and a reinforced alert mechanism, it delivers rapid environmental analysis and comprehensive protection for household security through multi-dimensional hazard prevention.
【Instant Alert Technology】RV carbon monoxide detector system activates visual and auditory warnings (≥85dB) when detecting critical thresholds (CO levels ≥150PPM / gas density ≥5%LEL). Flashing crimson indicators paired with piercing alerts ensure immediate threat recognition, enabling swift emergency response to safeguard loved ones in residential and mobile environments.
【Energy-Efficient Operation】Designed with sustainability, this US-standard plug adapter supports 110V-220V AC power with ultra-low standby consumption (≤2W). Its advanced electronic sensor technology eliminates frequent maintenance through extended operational longevity, offering an eco-conscious solution that reduces both energy waste and replacement costs.
【Bright LCD & Space-Saving Build】Features a bright LCD color display for easy reading of gas levels in real time, Detects carbon monoxide (0-2000 PPM) and natural gas (0-10% LEL). Compact design fits seamlessly in homes, RVs, hotels, and cruise cabins without taking up space.
【Initialization Guidelines】Allow 180-second environmental calibration post-installation. Conduct system verification through the manual test button to confirm alarm functionality. For optimal measurement precision, let the device stabilize thermally for 30 minutes before relying on humidity/temperature readings, ensuring sensor accuracy through proper thermal equilibrium.
