How to Choose the Best Gas Leak Detector – Buyer’s Guide

The importance of purchasing a great gas leak detection cannot be overemphasized especially since we are referring to a device that ensures that you stay in a safe environment all the time. Combustible gas detectors are designed to detect gas leaks or even the presence of gas around and this implies that they are pretty sensitive.

However, you do not want to be woken up by some blaring device in the middle of the night or be shocked out of your shins simply because you got a substandard device. Getting the best on the market is important for its functionality as well as durability and an assurance that you would only be alerted to a real possibility of danger. In order to choose the best gas detector on the market, here are some factors you need to consider:

1. Features

When you are looking to purchase a gas detector, you need to look out for the features that the manufacturer would have stated explicitly. If you intend to operate in an area that you may not be able to get to physically, then you would need to get one with a probe. Probes usually vary in length and the length that you go for also depends on where you intend to use it. In other words, the features literally make up your gas detector and go a long way in determining the kind of experience you would have using it. Also, gas detectors vary in terms of sensitivity, power source and a whole range of other features. You need to look out for features that actually suit you.

2. Price/Budget

While on your quest to purchase a gas detector, you need to keep in mind as a reminder, the actual amount that you are ready to spend. Even if you do not have an actual amount, you should definitely have a range or a budget. This would effectively guide you in making your eventual choice. There are different varieties of gas detectors on the market and each one comes at a different price than the next. Once you have a budget, you can easily eliminate the ones that do not fall into your budget range, after which you can then go ahead to get the best within your budget restrictions.

3. Purpose of Purchase

Considering the purpose of the purchase, you need to recall that there are different gas detectors and the fact remains that each one is best suited to use in a particular place or for certain purposes. For instance, all gas detectors do not come with the ability to detect the same gases. This implies that if you are dealing with the probable leak of a particular gas, you need to ensure that the gas detector that you are going for is equipped with the ability to detect that particular gas.

Similarly, some gas detectors are better suited to being used in certain places more than others. For instance, when dealing with hard to reach places, using a detector with a probe is the best move.

4. Ease of Use

It is really no use going for some device that would be terribly difficult to operate. Therefore, you do not want to go for a complicated gas leak detector that would be very difficult to use. If you have a measure of experience and you think that you can handle a pretty technical gas leak detector, then you can go right ahead. But if it is your first time getting a gas leak detector, then it is advised that you go for one that doesn’t reply reading through some thick manual or having to understand technical jargon. Simple models which are easier to operate are suitable for use at home and may even be used for commercial or professional purposes.

5. Durability

As much as you might be looking out for great features and functionality, it is essential that you do not compromise on quality or durability when making your purchase. As a matter of fact, the durability of your gas detector is one of the most important characteristics that you need to take care of.

You wouldn’t want to get a gas detector that goes bad after a few weeks or months so that you have to replace it. Instead, you need something that is very durable and you are certain that it would not malfunction shortly after you begin to make use of it. To determine the durability, you should take a look at the design and the manner in which it was put together or coupled. The warranty attached also gives you a hint.

Frequently Asked Questions

How Are Handheld Gas Leak Detectors Used?

To use handheld gas detectors, all you have to do is turn it on in a neutral location. Then move towards the place you suspect the leak is coming from. As you move closer, the device would begin to tick, beep or flash and it gets more intense with proximity to the source.

After Detecting a Gas Leak, Then What?

After detecting a gas leak, move away from the source and then contact your local fire department to come to check it out and take care of it.

What is the Difference Between Natural Gas and Carbon Monoxide?

Natural Gas is the gas you burn while cooking and can easily be detected thanks to the rotten egg additive included in it. Carbon monoxide, however, is a by-product of incomplete combustion and is very dangerous.

Criteria We Used for Gas Detectors Review

The following are the main criteria that we used in reviewing the best gas leak detectors:

1. Price/Budget

Gas detectors come with different price tags and all of these would, of course, fit into different budgets. Keeping this in mind, we ensured that we selected the best of different budget ranges just so that everybody can get functional and efficient gas detectors. While doing this, we made sure that we didn’t compromise on quality since purchasing a gas detector that doesn’t last is a clear waste of money. Similarly, we made sure that the prices were in line with the value that buyers would get from these detectors. For gas detectors whose overall package did not fit their price tags, we dropped and then kept the best.

2. Durability/Quality

The durability of the gas detectors we selected is one factor that we actually took into serious consideration. We understood the fact that most of these devices do not typically last and usually develop faults after a very short usage period. Therefore, we made sure that every gas detector on our last came with a great design and was made from very durable and long-lasting materials. To get an insight into what the manufacturers thought of their products, we checked the warranty that came with each as well as the manner in which it was coupled. For every gas detector on our list, the durability isn’t in question.

3. Reviews

Reviews are a great way of knowing whether or not a particular product is living up to expectations or is actually doing what the manufacturer claims that it would. In order to confirm the authenticity of the gas detectors that we reviewed, we went through the reviews that had been posted. These are basically first-hand opinions of users and therefore, they carry a great deal of weight. Knowing that there is a possibility of fake reviews, we went the extra mile to confirm especially in the case of negative reviews. Meanwhile, positive reviews without proper confirmation were not regarded.

4. Ease of Use

Irrespective of how any features a piece of equipment might possess, if it isn’t easy to use or operate, buyers would have a very hard time getting value for their money. While selecting gas detectors based on the factors mentioned above, we also ensured that the gas detectors despite the many amazing features that they might possibly have, be very easy to use.

Since gas detectors are mainly used by homeowners, it would be essential that the ones we selected would be pretty easy to use without requiring a lot of technical knowledge or the users having to study a special manual.

5. Features

The features of any equipment clearly define the measuring equipment itself; the features make it what it is. This is why we ensured that all the gas detectors that we reviewed had all the features that would be necessary for working on various projects that you might have in mind.

In addition to this, we rationalized that the more features that a gas detector has, the more functions it would be able to perform.

Features such as length of the probe, number of gases detectable, modes of alerting users, as well as power sources among others, were taken into consideration when we were making our decision.


Gas leak detectors are an essential part of every hour but you could experience quite a ruckus from time to time if you do not make a great purchase choice.
