Buying Guide – What is the best gas detector on the market?

Both to control the safety of the environment when using fireplaces or stoves and to prevent gas leak problems, a gas detector is an excellent aid that improves the tranquility of your home and your family. So that you do not have to resort to the canary or like the old miners, we present our guide to buying the best gas detector on the market with which to have the peace of mind that you and your loved ones deserve.

Measurement capacity

When buying a gas detector, it is necessary to take into account what we are going to need to measure. In the market we find from models that simply measure the concentration of carbon monoxide in the environment, perfect for where we have fireplaces or stoves, to more advanced models that measure the concentration of all types of gases such as butane, propane and the like.

Models that only measure CO are cheaper, and it is advisable to extend their installation range with several pieces of equipment in the room. The more parameters we need to measure, the more complex the device will be, so the more important its installation will be.

In any case, most of the equipment on the market has sufficient capacity to launch the alarm message when the gas concentration exceeds 3%, above what is reasonable, or when smoke is detected in the room, enough to prevent the normalized operation of optical-type equipment, which is a reduced concentration of that smoke.


In any gas detector comparison, the power options for these products make a significant difference to how they work. The two main lines are focused on products powered by batteries or similar, compared to products directly connected to the network.

In products that work with batteries we find the inconvenience that they can run out without us being aware of it and therefore we are left unprotected unexpectedly.

For this reason, it is convenient to look for models that warn of such a circumstance, maintaining its adequate activity. As for the models connected to the network, they have the advantage that they are always active, even when the power goes out, since many models have an internal rechargeable battery that keeps the equipment active in the event of a power failure.

warning system

In order to be aware of the activation of the alarm, the gas detector has two types of warnings: sound and light. The detector and its warning system must comply with the EN54 Fire Detection and Alarm Systems certificate, so if the equipment you are evaluating to buy does not comply with said standard, you should not buy it.

In fact, there is not much difference in how much equipment that meets the standard costs over one that does not. In any case, it is advisable to especially evaluate the intensity of the sound signals, since in the event of a fire or a complex atmosphere they are the ones that you will best perceive, even serving as a guide in the dark. In the case of light signals, the included LEDs or similar must have a high power that guarantees greater vision even in these complex conditions.

How to use a gas detector

In order to protect your home, workplace or other place where gas cylinders are used, it is necessary to protect them from the dangers of fire or domestic explosions, you have decided to buy a gas detector. Therefore, we have prepared this article with the purpose of informing you about how to use a gas detector in a safe and efficient way and that yours always stay safe.

Read the instructions for use and assembly

Before using your product, it is very important to review the instructions for mounting, depending on the model, since some work just by placing them in specific places. You also need to review the user guide to know its functions and features.

Locate the respective power supply of your product

Gas detectors vary in how they are powered and installed. Depending on the product model, proceed to place the respective power supply. Some models are very simple in this aspect, since they work only with AA or AAA alkaline batteries, these devices being wireless gas detectors.

Simply locate the compartment and insert the batteries as indicated in the user manual. Other models work with the electrical network, where they can be directly connected to a power outlet or require a more complex installation, depending on where you are going to place it, whether it is on the ceiling or on a special shelf for it.

Locate a strategic place to place your gas detector

Gas detectors are highly sensitive devices, therefore they must be placed depending on the type of gas they are going to detect. To detect heavy gases, butane or propane, the device must be placed 3 to 5 meters from the possible gas source and about 30 cm from the ground. In case of detecting a source of natural gas or methane, it should be placed at a distance of 30 cm from the ceiling.

Some devices include a hole in the back to place them on the wall, others have tilting legs to place them on a shelf or counter. If your gas detector works connected to the network, you can place it in a place close to the power outlet. In case your home has more than one floor, the ideal is to place a gas detector on each floor so that the place is safe and protected.

Use your gas detector

Once the gas detector is installed and the power supply is attached, the next thing is to press the test button, usually identified as TEST to show how the alarm sounds and the LED light changes.

Some models, when powered, do not need to be turned on, because they are automatically activated and the LED light is solid green. In the event that the device detects the presence of gas, the device’s sensor is activated, producing an audible alarm, usually loud, and displays an intermittent LED light, almost always red.
