Best Natural Gas Detectors

It’s estimated that 35% of American homes use natural gas for cooking, and about 50% use natural gas for either heating their homes or heating their water. It burns more cleanly than gasoline or coal and even has some advantages over electricity. But, there are also risks involved with natural gas. Hundreds of people die yearly in the United States from oxygen deprivation from a gas leak in their homes. And there are also around 280 incidents per year of explosions due to leaking gas that have destroyed homes and lives. These figures drive home the importance of a natural gas detector.

We’ll see that there are battery-powered, hand-held natural gas detectors that can help you discover any gas leak due to faulty installation of a gas heater or gas stove. There are also plug-in gas detectors that will help supervise your home against leaks of any combustible or toxic gas. Many of them will emit a noise or vibrate in accordance with the severity of the leak, making a higher-pitched sound when it’s an emergency. And many natural gas detectors are capable of detecting other dangerous gases as well. All told, a natural gas detector is a worthwhile investment to secure your home!

Looking at the Best Reviews Guide list of the best natural gas detectors, we see that there are a few varieties, both in terms of their construction, as well as in the information that they disclose:

• Gooseneck gas detector: These have the detector on the end of a long coil, or “gooseneck”. This allows you to insert the detector’s probe into tight spots to check if there is a gas leak. An example of such a detector is the UEi Test Instruments CD100A Combustible Gas Leak Detector.

However, one drawback of the UEi CD100A detector is that it doesn’t give any indication of the size of the gas leak. There are also gas detectors that give a visual and audible indication of how serious the gas leak is. The Techamor Y201 Portable Methane/Propane/Combustible Natural Gas Leak Sniffer Detector has 6 LED lights. More LED lights will light up on the device according to the severity of the leak. Also, it will produce a louder sound as it detects a greater concentration of natural gas.

• Wall unit gas detector: There are also natural gas detectors that you plug into the wall, either directly or with an extension cord. You can install them in a basement or kitchen, where there is the greatest likelihood of a natural gas leak. An example is the Cazoner Natural Gas and Propane Detector. It gives a loud beep and a red flashing alert light when the gas concentration has reached dangerous levels. (It lights up green when the gas levels are safe.)

However, the Cazoner gas detector gives you only a qualitative indication of the gas concentration. If you want a numerical display of the gas concentration, the Kidde Nighthawk Detector has that feature. It can detect propane gas, natural gas, carbon monoxide, and more. It displays the gas level in parts per million (ppm). Thus, you can also install it in your garage to monitor carbon monoxide levels.

Here are some impressions of customers regarding their choice of natural gas detectors:

• A necessity for service technicians: A professional HVAC service technician said that the UEi Test Instruments Combustible Gas Leak Detector was just what he needed. It detects a gas leak as low as 50 ppm and lets you decrease the sensitivity until you’re able to pinpoint the exact location of a gas leak. It can even detect methane if a person has flatulence!

• Auto-zeroing: Some detectors are auto-zeroing, where they go back to zero when you restart them, giving the reading for a fresh-air environment. But there is actually a preference for a detector that is not auto-zeroing so that you can set the baseline amount of gas to what was measured previously.

Here are some tips and important features to look for when selecting a natural gas detector:

• Detector sensitivity: You’ll see detectors that can be set for high or low sensitivity. For example, the Klein Tools ET120 Gas Leak Detector can be set at high sensitivity, detecting methane from 50 to 10,000 ppm, or low sensitivity, detecting methane from 1000 to 10,000 ppm. Adjusting the sensitivity will help you pinpoint the exact location of a gas leak.

• Types of gases detected: Many of these natural gas detectors will help discover other gases as well. Besides methane, the Ridgid 36163 Model Combustible Gas Detector is capable of detecting propane, butane, ethanol, ammonia, hydrogen, and other combustible gases. The Kidde Nighthawk Detector will also pick up the presence of carbon monoxide, which is a dangerous by-product of improper combustion. It can also lead to asphyxiation by destroying the body’s ability to absorb oxygen.

Final Verdict

We went through some of the specs of the best natural gas detectors. They can provide qualitative and quantitative measurements of the presence of natural gas, carbon monoxide, and other dangerous gasses. Whether you use one as part of your work, or just as a measure to keep your home safe from gas leaks, a natural gas detector is a small investment when compared to the damage that can result from a gas leak.
