Product description

Did someone leave the stove on?

Reduce the risk of gas leaks and enjoy greater peace of mind with this combustible gas detector. Unlike basic alarms, this device displays gas levels clearly on an LED screen with continuous real-time monitoring. If dangerous levels are detected, a loud audible alarm and flashing light provide immediate warning—helping you avoid hazards like unattended stove use, gas buildup, or potential explosions.

As a U.S.-based seller, we provide ongoing expert support, including access to a Midwest-based team who can answer technical questions. This detector is rigorously tested to meet UL 1484 safety standards, offering reliable protection against suffocation risks and explosive gas hazards in your home, kitchen, RV, or camper.

Unless a ceiling AC outlet is available, alarms that plug directly into AC outlets may not allow for early detection of natural gas which is buoyant and accumulates near ceilings.

Why a Gas Alarm Is Essential for Every Home, RV, or Kitchen

Combustible gas leaks—such as natural gas (methane), propane, or butane—are invisible, odorless at low levels, and potentially life-threatening. A gas alarm gives you the critical early warning needed to prevent accidents, fires, or even explosions. Whether caused by a forgotten stove, faulty gas line, or appliance malfunction, leaks can escalate quickly if unnoticed.

With a gas leak detector, you gain protection and real-time awareness of gas concentration levels. The device alerts you instantly—long before levels become dangerous—using a loud alarm, voice warning, and visual indicators. This early detection not only protects lives but also helps prevent property damage, reduces costly emergency repairs, and gives peace of mind to families, renters, and RV travelers alike.

By installing a gas alarm in your home, kitchen, camper, or trailer, you’re taking a proactive step toward safety—backed by science, safety standards, and smart technology.

1 Gas Detector Double-sided Adhesive Mounting Tape Patch2 Mounting Screws for Detachable BackplateUser Manual
Operating Voltage: AC 110V – 240V Audible Alert: Loudspeaker (Voice Alert) Alarm Volume: 85 dB at 1 m Working Temperature: 0 °C to 55 °C Ambient Humidity: ≤ 95% RH Item Dimensions: 132 x 91 x 39 mm AC cord: 6 feet

Adjustable alarm placement for MOST accurate gas detection

As natural gas rises but propane sinks, placement near the ceiling or floor depending on gas type will improve alarm sensitivity. Place alarm near ceiling for natural gas. That’s why our device includes an AC cord for locations where a ceiling outlet is unavailable, something more basic alarms simply don’t have!

Testing/Tips:

Due to added odorants, people may begin smelling a gas leak at 1% LEL whereas available retail gas alarms set an alarm threshold of 5%-25% LEL to avoid frequent false alarms. Do not be alarmed if you can smell gas before the device alarms.Every couple weeks, test your alarm with unlit butane from a cigarette lighter or propane source.Avoid placement where airborne contaminants like cooking oils can coat and decrease sensor sensitivity.

ENHANCED SAFETY – Protect your home and family with this plug-in gas leak detector. It emits a loud 80dB siren, voice alarm, and flashing red light when combustible gases are detected—such as methane (natural gas) or propane—before they reach dangerous, explosive levels. Ideal for kitchen, camper, or RV use. Tested to meet UL 1484 safety standards for added peace of mind.
REAL-TIME GAS MONITORING – Continuously detects and displays the concentration of combustible gas on a clear LED screen, from 0% to 20% of the Lower Explosive Limit (LEL). Alerts activate when levels reach 5% LEL, giving you early warning before gas reaches a dangerous or explosive concentration. Features both audible siren and voice alarm for immediate awareness.
ENERGY-EFFICIENT & COST-SAVING – Uses less than 3 watts of power, making it an eco-friendly choice with minimal energy consumption. Helps prevent accidental gas leaks—like leaving the stove on—potentially reducing your gas bill and environmental impact.
DURABLE & EASY TO CLEAN – Built with a tough, double-sided ABS shell that resists wear and wipes clean with ease. Designed for long-term use in kitchens, campers, RVs, and other high-traffic areas.
EXPERT DESIGN & LIFETIME U.S. SUPPORT – Backed by a Midwest-based chemist and dedicated customer support team to assist with any questions. Includes a free 20+ page eBook on gas and air quality hazards—an added resource to help you stay informed and protected.
