4-in-1 Carbon Monoxide Detectors, Smoke Detector, Natural Gas Detector, Propane Detector, CH4/LPG/Smoke and Carbon Monoxide Detector,Battery Powered,LED Light,Gas Leak Detector for Home,RV (Black)

4-in-1 Multi-functional Gas Detector Gas：Smoke/Carbon Monoxide/Methane/Propane Powerful Supply： DC4.5V（3 AA Battery） Working Current：＜45uA Alarm：≥85dB (1m in front) Relative Humidity： <95%RH, No condensation Alarm Mode： Audible and Visual Alarm

• 【4-in-1 Gas Leak Detector】Gas leak detector combines the functions of a natural gas detector , carbon monoxide detectors, smoke detector, and propane detector. The multi functional gas detector can be used as smoke carbon monoxide detector,travel carbon monoxide detector,propane gas detector and natural gas detectors for home.Combination carbon monoxide detector accurately identifies various hazardous gases and provides immediate alerts to ensure household safety.
• 【Visible & Audible】When gas levels reach a dangerous threshold, 4-in-1 carbon monoxide detectors battery activates, emitting a loud alarm of ≥85 dB and a flashing red light to immediately alert you and your family in the event of a leak. Three LED indicators show status: green (normal), yellow (fault), and red (alarm). Simple to use.
• 【100% Powered by Battery】Natural gas leak detector is powered by 3* AA batteries, offering extended battery life for continuous protection. With its wire-free design, simply install the batteries and it's ready to use. The device can be easily mounted on any wall or ceiling.
• 【Sleek and Compact Design】Multi-function natural gas leak detector, multi-function propane detector,seamlessly blends into any home or office setting, making it ideal for use in houses, RVs, hotels, kitchens, and cruise ship cabins without taking up extra space.
• 【Accurate detection】Combination CO detector adopts high-sensitivity photoelectric sensors and electrochemical sensors, which can accurately detect smoke, CO, propane and natural gas(methane).
