While carbon monoxide is a chemical that you can't see or smell, it is odorless and colorless, and at high concentrations it can lead to poisoning and death. While carbon monoxide is widespread in modern home gas appliances, such as a gas stove or water heater, the dangers of CO can only be detected by use of a gas sensor. Gas leak detectors detect the presence of carbon monoxide, and alert you to the presence of any leaks. The 10 leak detectors in our roundup are easy to use, compact, and portable, making them a perfect option for those dealing with leaks in their home. We've tested everything from precision, digital CO detectors to simple, analog models that don't require a battery, and we've ordered them based on our expert opinion.

Carbon monoxide can slowly leak into your home from a number of sources, from unclogged or dirty vents, to faulty appliances. Without early detection and remediation, carbon monoxide can lead to serious health problems and even death. So, to keep it out of your home, it's recommended that you regularly check your appliances for carbon monoxide leaks. To do this, rely on a carbon monoxide detector when cooking or sleeping in your home. And after the last meal, be sure to wipe down your range, cooktop, and oven with paper towels to remove any grease that might be cooking.

The system warm-up time is about 2-3 minutes. During this time period, the gas test will not work. You need to wait for the display to show 0 (the system enters the working state) before it can be tested normally.Gas leak detector adopts Easy-to-install Design, can be used by plugging directly into the power socket to detect leaked gas.

The Gas Detector offers several useful features, including a clear, easy-to-read digital display, and it uses an audible and visual alarm when the gas level reaches a preselected level. The audible alarm is loud enough to be heard in a busy kitchen, but it's not quite as loud as the gas alarms used by professional chefs, so it's less annoying than some gas alarms. The alarm works well, and the unit's digital display shows the current gas level so you can easily gauge when the alarm will sound. The Gas Detector offers voice notification when the gas level reaches a preselected level, and the voice alert is only slightly annoying. The Gas Detector also can be plugged into a power outlet, so you can use it independently in your home, or combine it with a home alarm system, and it's relatively easy to install. The only thing we dislike about the Gas Detector is its large size. It's slightly bigger than most gas detectors, and it's a little heavier, too.

GasKnight 2.0 Natural Gas Detector & Propane Detector w Display. LCD Natural Gas Alarm / Monitor for Home

by GasKnight

✅ STAY STYLISH This newly released natural gas alarm is sleek and modern and has a beautiful blue LCD screen that will complement the style of your home or camper without detracting from your interior design.

The GasKnight 2.0 is easy to set up and use, and it offers a number of advantages over our other top pick for natural gas detectors. It has the longest power cord of any detector we tested, which means that you can install it in an ideal location in your house for optimal gas detection. The LCD screen is easy to read, and the robot-voice alert offers lots of information, including which gas was detected, the percentage of gas in the air, and the amount of time since the alarm was triggered. The GasKnight 2.0 is the only gas detector we tested that detects both natural gas and propane. It's also the only detector we tested that detects methane, an odorless, colorless, highly flammable gas that's often found in natural gas. The GasKnight 2.0 is also the only detector we tested that detects ethane, another odorless, colorless, highly flammable gas that's often found in natural gas. The GasKnight 2.0 uses an electrochemical sensor to detect gas, which means that it can detect gas in a closed space, such as an enclosed garage. The sensor is very sensitive, so it requires minimal calibration, and we found that the sensor was rarely triggered by outside airborne gas. The GasKnight 2.0 is more expensive than our other top picks for natural gas detectors, but it's the best overall detector we tested, and it offers the peace of mind that comes from knowing there's gas in your home.
