10 Best Propane Detectors 2025 in the United States

The KOABBIT Combination Gas & Carbon Monoxide Detector is a versatile 4-in-1 device that monitors propane, natural gas, carbon monoxide, temperature, and humidity. One of its notable strengths is the real-time digital display, which provides users with immediate information on gas levels and environmental conditions. This feature adds a layer of convenience and peace of mind, especially for those living in areas where gas leaks might pose a risk.

The detector operates on a plug-in power source, eliminating the need for batteries, which can be a hassle to replace. With an 85dB alarm, it effectively alerts users to dangerous gas levels, making it suitable for home use, kitchens, or RVs. Its lightweight design (only 0.05 pounds) also makes it easy to install in various locations without taking up much space.

There are a few considerations to keep in mind. While the 4-in-1 functionality is a major benefit, the sensitivity of the sensor may vary based on environmental factors. Some users have noted that it occasionally gives false alarms, particularly in high-humidity areas.

The Tadeto RV Carbon Monoxide and Propane Gas Alarm is designed specifically for use in RVs, trailers, and campers, providing combined detection of carbon monoxide (CO) and propane gas. This integration means you don't need separate devices for each gas, offering convenience and safety. It features high-sensitivity electrochemical sensors that quickly identify even small leaks or rising gas levels, helping protect you from invisible dangers.

The alarm alerts users with a loud 85-decibel sound and a flashing red light, ensuring notifications are noticed even in noisy environments or while asleep. Its clear backlit display shows gas levels in real-time with large numbers for easy monitoring at any time. Powered by a 12V DC hardwired source, common in RV setups, it eliminates concerns about battery replacements. Installation is straightforward with included screws, Velcro options, and a connector that avoids messy tape or wire wrapping, making mounting safer and easier. It requires an existing 12V power supply, so compatibility with your RV’s wiring is important.

Weighing about 4.5 ounces with a compact size, the unit occupies minimal space. This Tadeto model has received positive user reviews for its reliability and ease of use. For RV owners seeking a dependable, dual-function gas alarm that’s easy to install and monitor, it represents a solid choice.

The Safe-T-Alert by MTI Industries 35-742-BL Dual LP/CO Battery Powered Alarm is a versatile device that detects both propane (LP) and carbon monoxide (CO) gas leaks simultaneously, adding an extra layer of safety. It operates on a 12V battery, eliminating the worry about changing or missing batteries, which is convenient for continuous use. The flush mount design allows it to blend seamlessly into walls or ceilings, making it less obtrusive in your home or RV.

The alarm is audible, ensuring that you're promptly alerted to any danger. It's built to withstand a wide range of temperatures, from -40°F to 158°F, which makes it reliable in various climates. The product meets RVIA and NFPA requirements and is UL listed, ensuring high safety standards. However, it’s important to note that the device is battery-powered, which could be limiting if you prefer a hardwired option. The plastic construction, while durable, might not appeal to those who prefer metal devices for their perceived longevity.

Additionally, the product dimensions are relatively large at 2 inches in depth and 10 inches in width, which could be a consideration for some installation spaces. The alarm type is photoelectric, which is effective but may be slower in detecting fast-burning fires compared to ionization alarms. This propane detector is a reliable choice for those looking for dual protection in a single device, particularly well-suited for RV owners and those needing an easy-to-install solution.
