10 Best Gas Leak Detectors

 

Kidde Nighthawk

Kidde Nighthawk
This is one of the best carbon monoxide and explosive gas detectors. We are talking about a compactly designed device that provides outstanding performance. It’s powerful enough to notify you about any possible gas leakage – no matter where you place it, Nighthawk will detect potential danger!

Extremely Loud
People are thrilled with this device because it is able to detect a gas leak from an incredible distance. After it detects the leak, the device triggers the alarm which you’ll be able to hear for a mile away – that’s how loud this detector gets. You definitely won’t be sleeping if the leakage occurs! There were even some users that complained about it being too loud for small apartments, but it’s better to hear it clearly than not hear it at all. Another useful feature is a digital display that shows the level of gas that the unit is sensing. There is a test or reset button that allows you to quickly test the device or silence the alarm. Also, the tiny LED light will notify you if the device is not working properly.

Three Mounting Options
When it comes to the installation of this device, things are pretty simple. You have three mounting options, you can plug it directly in the power socket, mount it anywhere on the wall or place it on the table (or any other surface) and run the power cord to the outlet. The 6-foot power cord should be long enough for you to plug it whenever you find convenient. While it runs on electric power it also has a backup battery for unobstructed and continuous working. However, we would like to see improved battery life. Even if it runs primarily on the electric power, in case it switches on the battery it will drain it out pretty quickly, and you’ll soon need a replacement.

Cost and Value
This is definitely not the cheapest option out there, but it’s the best device that you can get and it won’t cost you a fortune! It also comes with a 5-year warranty, and many users reported using it for around 7 years before they needed a replacement.
Pros

Detects gas from an incredible distance

Compactly designed, allows for three mounting options

Outstanding performance

Loud alarm

The digital display shows the level of the detected gas

Excellent value for the money

Cons

Battery life should be improved

Another great thing about this device is the fact that it allows manual adjustments of the sensitivity level. Considering how incredibly sensitive it is regularly, you’ll find yourself using this feature quite often. The only drawback is the lack of some kind of case or storage bag that would protect the item when not in use. It can get damaged in the regular toolbox.

Cost and Value
We weren’t so surprised by the fact that this exceptional device comes with a sky-high price tag. It does offer incredible performance and portability after all.

This is a very sensitive device that you can adjust according to the specific situation – you can reduce or increase the sensitivity dial according to the concentration of the gas. It features both audible and visual alarms so it will notify you with the loud sound and LED flashing light when it senses the leaking gas. The louder the alarm gets the stronger concentration is present. The only thing missing is a way to find out PPM. The manufacturer should improve this in the future for more accuracy.

Excellent Mobility
Sgile comes with a 12 inches flex probe and allows for great mobility around your household. It lacks some additional features needed by contractors and installers, but it proves to be more than enough for every household that has gas-powered appliances.

You’ll especially like the fact that it doesn’t require any maintenance. This device offers continuous working on 2-cell alkaline batteries that have no limits like regular ones.

There is a sturdy storage bag included in the package though, so you can store it there for more protection when not in use.

Adjustable Options
You’ll love this portable device that is designed for simple and easy operation. It comes with a 14 inches long stainless steel probe that you can use to move around freely, and control all hard-to-reach areas.

The incredibly loud alarm will notify you about the danger using LED light along with the audio sound. It will also give you accurate measurements on the LED screen so you’ll know how strong is the gas concentration. Also, it’s worth mentioning that this device plugs into the standard outlet, meaning you won’t have any maintenance issues. However, it doesn’t have battery backup which means it will turn off completely if the power goes off.

Sturdy Exterior
Another great thing about this device is a small energy footprint. It will also save you a lot of money by notifying you when you forget to turn off the stove. We especially liked its durable exterior made of double-sided ABS as well as anti-corrosive and anti-mildew design.

The best thing about this device is the fact that it detects gas leaks in closed piping systems. It requires less than one minute to accomplish full potential. The audible alarm and LED lights will inform you if there’s any dangerous gas concentration to worry about, and you’ll get the accurate measures of the gas concentration right away on the display. We especially liked the auto power-off feature that preserves battery life. The device will automatically turn off when not in use (after 10 minutes).

Portable
Amprobe comes with a flexible stainless steel probe that allows great mobility. The probe is 17.6 inches long, which is quite impressive compared to the competition. You can finally get to examine all those hard-to-reach areas and make sure there’s no dangerous leakage. When it comes to the protection of the device itself, the package includes a sturdy carrying case as well as a sensor cap for advanced protection during transportation and storage.

Cost and Value
While we couldn’t find any issues with the performance and quality of the device itself, we found one big drawback – Amprobe is very expensive.

For more information about this excellent device, keep reading our in-depth review!
Expand to see more
Simplicity
Mastech features a powerful sensor that can easily detect almost all types of gases, including gasoline, methane, propane, ethane, and others. It comes with an audible alarm that will notify you when the sensor picks up from 10 to 40% gas leakage. You can also adjust the sensitivity dial to suit your current requirements. The only thing that bothered us is a bit slow response. It takes quite some time to warm up to the highest sensitivity, which can be pretty annoying.

Portability
As we already mentioned above, this is an extremely portable device that you get to carry around and inspect all potentially dangerous areas. Not to mention how intuitive design it provides, allowing you to operate the device with great ease. Also, we shouldn’t forget to mention that it runs on batteries which you’ll have to purchase separately.

General Tools

General Tools
Here we have a handheld style coming from the well-known General Tools. This device is the most portable option on the market, allowing for simple use and accurate gas detection. Both professionals and homeowners will definitely benefit from this tiny yet powerful device!
Expand to see more
Excellent Accuracy
This tiny pen-like device has surprisingly high sensitivity power and excellent accuracy. It offers a LED light that indicates the gas leak – the green light tells you it’s there, the yellow shows 200 PPM, and the red light warns about 500 PPM. Overall, you’ll be quite satisfied with the response time and overall performance, but keep in mind that this is not a heavy-duty gas leak detector. It won’t pick up low concentrations because it’s mainly designed to read the leak directly from the source. If you need a more powerful device to detect a low gas concentration, you should search for another option.

Easy to Use
Like the name says itself, this is a one-handed device that’s very useful and easy to operate. It’s extremely lightweight so you’ll feel like holding the real pen. This makes it very useful for all kinds of situations. You can easily store it in your toolbox and transport it for spot leak detection around the house or at the construction site. The batteries are not very durable, but we are talking about regular AA ones that you can replace in a matter of seconds.

Cost and Value
General Tools offer this incredibly valuable product at a great price. Sure, it’s not a highly sensitive device, but it does offer excellent performance for a spot-detection. It is a basic device after all. You can easily purchase it to complement your home security system, and examine all hard-to-reach areas when necessary.

It might not seem so powerful at first sight, but it does offer incredible results! Camco can discover even the smallest leaks in a few seconds.
Expand to see more
Efficient
Camco comes in an 8-ounce sprayer bottle. It effectively detects gas leaking problems right on spot, you just need to spray it on the problematic area and see if the bubbles will show up. It takes only 5 seconds, and the results are incredibly accurate! Our only complaint is about the design of the nozzle. The manufacturer should improve this in the future because the nozzle tends to loosen up over time and then it’s hard to spray the liquid.

No Skin Irritation
This is quite easy to use, as we already mentioned above. The best thing about it is the mild formula that won’t cause any irritation if the liquid somehow ends up on your skin. You might even find it quite useful for many years because a small amount goes a long way!

Cost and Value
Even if it’s not a heavy-duty device that detects the problem from a mile away, this device is a great option for all those who want a cheap and accurate gas detector. One is certain, this is the cheapest option on the market, and it provides incredible value!

Criteria Used in Evaluation of the Best Gas Leak Detectors

 

Along with choosing the best gas leak detectors on the market, we had a difficult task to rank them from 1 to 10 according to their overall performance and quality. As we only have first-class devices on the list, this required a lot of research and nitpicking over tiny details, but we made it! If you’re interested in the used criteria, we prepared a short list with some of the important factors:

Sensitivity

First and foremost, every gas leak detector has to be powerful and sensitive enough to detect leaking gas from a large distance. The ones that trigger the alarm only when they sense the strong concentration are not reliable enough! That’s why the most important thing in the evaluation was the provided level of sensitivity. Those detectors that have to offer the best performance in detecting leaks are on the top of our list, while the weaker ones are at the bottom.

Battery

Having a long-lasting battery is one of the most important things when it comes to every gas leak detector. It makes no sense struggling with poor batteries all the time when you need a continuous power output to search for the problem around your house. Also, it’s nice to have backup batteries when using the device that connects to the regular power outlet. If the power goes out, it should still work for maximum protection. Therefore, the quality of batteries was one of the most important things in the evaluation. Those products that are on the top of the list definitely provide the best performance thanks to the first-class batteries.

Portability

There are many wall-mounting gas detectors that can’t be moved around, but they allow for easy installation and many mounting options. We assigned some additional points to all devices that can be installed in various locations. However, portability was the main concern when it comes to hand-operated gas detectors. They are primarily designed to allow simple handling and easy carrying around for detecting leaks in all hard-to-reach areas. Therefore, it was important to determine how portable is every product on our list, and then rank them according to their results. Also, it is important that highly portable devices have a sturdy exterior that can protect the inner parts in case of accidental falls. Not to mention that they have to have long flex probes to be portable in the first place.

User-Friendly Features

We all know how important is to have a gas leak detector that allows for all kinds of adjustments. It’s crucial to have a device that you can adjust to suit your requirements in every given moment. The best products are those who allow sensitivity adjustments because you can accurately and quickly detect all leaks, no matter how big or small they are. Other important things include having a reset and power button that allows you to immediately turn the device off. This is very useful when you already located the issue and you want to stop that annoying alarm sound. There are many similar options that allow easy adjustments for flawless performance, and we took all of them into account during the evaluation.

Cost and Value

Lastly, we have to agree that these are rather expensive devices. While we are all ready to spend some extra cash on such a useful device, we want to know that we’ll get what we paid for. Naturally, we don’t want to spend a fortune on the device that doesn’t provide what we need! Also, there’s no use of a cheap device that won’t provide enough accuracy. Therefore, while our list contains both budget-friendly and pricey products, we made sure to examine the value that every product provides for the money, and notify you about their results.

 

Other Factors to Consider

 

Before you make up your mind and purchase one of these great devices, we recommend taking a few more minutes to examine some additional factors that could influence your final decision. Here is what we have in mind:

Type

You should ask yourself which type you want in the first place. There’s a wall mounting option that allows simple installation and works continuously to provide superior protection. On the other hand, you might want to have a portable device that you can use to detect issues all over the house, even in the most remote areas. Think wisely before you make a decision because one device will cost you quite some cash. You probably won’t get a new one any time soon if the chosen one doesn’t fulfill your requirements.

Features

Every device comes with various features designed to enable simple and accurate detection of leaks. You should think about each one of them before you decide to purchase a certain product. Otherwise, you might end up completely unsatisfied with the device, even if it does provide an accurate reading. For example, you should ask yourself whether you need a LED light or you only need a loud alarm. Maybe the installation and mounting options won’t meet your requirements, or the provided probe isn’t long enough to allow for great portability. What about the protective exterior or storage case? There are many things to examine before you pick and we recommend doing it before you make the purchase.

Budget

The main reason why gas detectors are expensive is the pricey technology that allows for accurate gas measurements and high sensitivity. In order to work properly and perfectly, they contain many expensive features. You can find a cheap device that still offers incredible value, especially if you need one for smaller areas, but we advise you to make sure you’re buying a device powerful enough to detect every leak. This device is designed to keep you safe from harmful substances, so don’t hesitate to spend a few more bucks on it.

 

FAQ

Frequently Asked Questions

 

Q: What is this device, anyway?

A: It’s a device designed to detect the leak in a certain area. Firefighters, HVAC technicians, and other professionals use this device all the time as well as all people that have gas appliances in their homes. Actually, most countries have a law regulation that prescribes having one of these devices in your house. The device has a sensor that detects the gas concentration and notifies about the potential danger by triggering an audible alarm and (sometimes) LED light. There are many types of gases that could bring your life in danger, so having a detector in your house is very important and you should take it seriously!

Q: Which type of these devices exist?

A: Two common types include a portable style and a fixed one. The portable device allows for great mobility, so you can use one hand to operate it and carry it around searching for possible leaks. This is an excellent option for those who have a lot of hard-to-reach areas that could be potentially dangerous. On the other hand, the fixed type allows for continuous protection because it works all day and all night. If there’s an accidental leak in the middle of the night, this device will wake you up by triggering a loud alarm. Both types have their pros and cons, so people mostly purchase a certain device according to their personal preferences and home requirements.

Q: How long will they work?

A: It depends on the quality of every device. While most devices work from 3 to 5 years, some of them can even withstand 7-10 years without any issues. However, don’t forget to calibrate the device every year (or sooner) to make sure that it still works perfectly.

Q: What should I do when it notifies me about the gas leak?

A: No matter how strong concentration your device detects, the smartest and the safest thing you could do is to leave the area and wait for the gas company to come – especially if the alarm wakes you up in the middle of the night. However, most people first look up to the level of concentration and then leave the area until it’s well ventilated. This is mostly the practice when using a portable device because people use it when they already know about the leak, and they only want to know the exact location! Either way, don’t rush into the dangerous area, and always keep close a clean piece of cloth to cover your mouth and nose.
