Product description
Plug in Combination Gas & Carbon Monoxide Detectors
Experience confidence with our plug-in gas & carbon monoxide detector, designed for homes, offices, hotels, restaurants, and apartments. This advanced monitoring system combines real-time digital tracking of natural gas (0-10% LEL) and carbon monoxide (0-2000ppm) levels, ensuring instant alerts at critical thresholds.
This fire detector and carbon monoxide detector is equipped with voice alerts ensures that people can tell the exact alert.
Critical Advantages:
Immediate Voice & Visual Alerts: 85dB audible alarm with flashing red LED activates when gas levels exceed threshold (5% LEL for gas, 150ppm for CO)
Continuous Monitoring: Always-active green indicator light confirms proper operation
Self-Test System: Verify functionality with single-button diagnostics
Precision Monitoring Capabilities:
Operating Voltage AC 110V-220V
Response Time =180S Warm-Up Period
Environmental Tolerance 0-99% Humidity | 1-176℉
Power/Fault/Alarm Indicator
3 indicators for this carbon monoxide detectors plug in ensure that anyone can tell its working status.
Self-Test Button
Self-Test button for plug in combination gas & carbon monoxide detectors ensures that people can test its working status.
Easy Usage and Small Size
Portable CO gas detector is mall size, it is suitable for travel. Plug the combination gas and carbon monoxide detector into the socket directly, no complicated installation process.
Optimal Installation Practices:
Position device in well-ventilated areas away from mechanical airflow
Conduct weekly maintenance using soft brushing or vacuum cleaning
Avoid placement in areas with excessive airborne particles or vapors
Why Choose This Detector?
Protection with gas and co sensors meets residential convenience. The clear digital display provides instant readings of %LEL, PPM, °F, and %RH, empowering users with critical environmental data.
Important Notes:
• Designed for combustible gas and carbon monoxide detection exclusively
• Routine maintenance required for optimal performance
Plug-in Carbon Monoxide Detector with 85dB Alerts:Instantly powered via AC110-220V outlets, activates triple alarms (voice/light/sound) at 150ppm CO or 5%LEL gas.Carbon Monoxide Detectors Plug In with electrochemical accuracy for 0-2000ppm monitoring
Plug in Combination Gas & Carbon Monoxide Detectors: Dual sensors detect natural gas leaks (0-10%LEL) and CO levels faster than standard gas detectors, validated by real-time %LEL/PPM display
Carbon Monoxide Alarm with Precision Self-Test: One-touch verification triggers flashing yellow-red LEDs and alarm beeps. Continuous monitoring ensured via green status indicator
Combination Gas and Carbon Monoxide Detector 4-in-1 Multifunction: Tracks °F (1-176℉)/humidity (0-99%RH)/gas/CO with its sensors. Portable CO Gas Detector handles extreme conditions
Natural Gas Leak Detector & Carbon Monoxide Detector: 180-second preheat optimizes stability, compliant with commercial/residential standards for hotels, apartments, homes,office
Auto-recovery:After going off because of reaching the thredhold(CO exceeds 150ppm or gas reaches 5%LEL), this carbon monoxide detectors plug in will recover its normal working status automatically when CO is less than 150ppm or gas is less than 5%LEL

Must-have for home safety!
This 4-in-1 gas and carbon monoxide detector gives me peace of mind. The digital screen is bright and clear, and I love that it shows temperature and gas levels in real time. Setup was easy just plug it in and it starts working. I tested it near my stove and it accurately picked up gas levels, which reassures me that it’s functioning properly. The design is modern and compact, and it doesn’t take up much space. If you want to protect your home and loved ones, this is a solid, reliable choice. Definitely worth it!

Small and bright!
I love this electronic carbon monoxide detector! It is so easy to set up. We had previously only used simple detectors but I love how this one has all kinds of features and even speaks! It also tells you the temperature of the room.

Talking 4 in 1 detector
I was pleasantly surprised to hear this 4 in one carbon monoxide detector talk as soon as I plugged it in! The readings are colorful and very easy to read! I feel safer knowing that if a gas leak were to occur in my home, I will be alerted immediately! It even has a readout for inside temperature as well as humidity! The instructions were clear and super easy to follow! I highly recommend this truly awesome 4 in 1 detector that even does natural gas too!

Great Product
I order this for the lake house and for traveling. It is really small and easy to pack in luggage. It seems to work really good. I like that it has a digital display and is so easy to use. You just plug it in and it sets itself up and even has a test button to ensure it works.

Safety CO/gas detector
A handy and necessary device to have in home for health and safety. It is voice activated when plugged in and starts CO measurement right away with a countdown on the device. When the countdown is finished, the CO/gas reading should be 0. The voice activator is not very loud, but enough to be heard in my small home, so a consideration would be to get more than one device for larger or multiple-storied homes. There’s also a self-test push button as an added measure to its working capability.I was primarily looking for a carbon monoxide detector, but since I have multiple gas appliances, it was a bonus to find this multi-function 4-in-1 plug-in device that also tests for gas leaks. I noticed the temperature reading on the plug-in is 2 degrees higher than my thermostat/humidity weather detector. The humidity reading on the plug-in is 8 degrees lower than my thermostat/humidity weather detector. So, I can’t say which device is more accurate but just noting the difference. The readings are clear and easy to understand with the green power light on, yellow for fault, and red for alert. The temperature, CO/gas, and humidity readings are a light blue color. Another feature I like is the illumination at night also serves as a subtle night light in an otherwise dark room.
