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, propane, 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.
