Gas detectors are lifesavers. Time and again, we hear about gas explosions and deaths from suffocation due to gas accidents. That's exactly what you can protect yourself against with gas detectors. They measure the gas content in the air and warn you in good time before the value becomes too high so that you can take countermeasures in good time. Depending on the device, you are not only protected when you heat or cook with gas, but also from carbon monoxide, which is produced during an incomplete combustion process.
In our big gas detector test 2021 we show you what you should look for when buying such a device and help you to make the best possible decision. Here you can find out which gases you should protect yourself from, what types of gas detectors there are and what you should do if your device sounds the alarm.

- Gas detectors measure the level of explosive gases and mixed gases in the air and sound the alarm if it is too high, so you can react in time before it is too late
- Gas detectors can mainly detect and warn about 4 different types of gases. These are: Carbon monoxide, natural gas, liquid gas and narcotic gas
- For permanent protection against gases, a stationary gas detector is suitable, as it measures the gas content in the air at all times

Guide: Questions you should ask yourself before buying a gas detector
Why do you need a gas detector?
Gas detectors measure the level of explosive gases and mixed gases in the air and sound the alarm early so that you notice in good time if you have a gas leak in your motorhome or home. This way you can act immediately before a gas explosion or carbon monoxide poisoning occurs.
Such gas alarms are especially useful for people who use a cooker with a gas hob or use a gas cooker when travelling.
Are gas detectors compulsory?
However, in many households or when camping, it makes sense to get a gas detector, as most gases are colourless and odourless and are therefore only noticed much too late.
At night, our sense of smell is switched off, which is why escaping gases go unnoticed, especially at night.
In flats and houses with gas heating systems, gas ovens, gas heaters, gas cookers or gas fireplaces, it makes a lot of sense to think about getting a warning device. But a gas detector is also recommended for mobile homes, where a lot of gas is used.
Carbon monoxide can develop wherever combustion with gas, coal, oil, petrol or wood takes place. Therefore, a CO alarm is worthwhile even if you do not use gas in your home. Possible sources of danger for the development of carbon monoxide are, for example, oil or wood stoves, fireplaces, open fireplaces or cars in closed garages.
What does a gas detector cost?
Simple gas detectors are available from about 25 €. If you are looking for a carbon monoxide detector, you will find products starting at 15 €.
However, keep in mind that a gas detector can save lives in an emergency. Therefore, it is recommended that you dig a little deeper into your pocket and not go straight for the cheapest product. Many experts recommend spending between €50 and €100 to get higher quality and safer products.
|Carbon monoxide detector||15-60 €|
|Gas detector||25-200 €|
How long do gas detectors last?
Unfortunately, gas detectors only have a limited lifespan because the sensor built into the device is very sensitive and wears out over time. Gas detectors last about 5-10 years, but you should pay attention to the manufacturer's exact specifications as to when your device needs to be serviced or replaced.
Also note that some gas detectors are battery operated. This may need to be replaced beforehand. With a permanently installed battery or a device with a mains connection, you can of course save yourself the trouble.
Decision: What types of gas detectors are there and which is the right one for you?
If you want to get a gas detector, you can choose between two options:
- Stationary gas detector
- Portable gas detector
One type is not fundamentally worse than the other, it just depends on what you need and what suits you and your requirements better. We have listed the advantages and disadvantages of these options below to help you decide what to buy.
What distinguishes a stationary gas detector and what are its advantages and disadvantages?
Stationary gas detectors are permanently installed in your flat or house by screwing them onto the ceiling or wall.
Since stationary gas detectors permanently measure the gas content in the room, you are always safe from possible gas leaks. As soon as a certain value of gas content in the air is exceeded, the alarm sounds and you can take protective measures. Stationary gas detectors are usually cheaper than mobile gas detectors.
Stationary gas detectors are permanently installed in the home, which is why you can only use one device in a room at a time. Therefore, you may have to buy several gas detectors for your home. Also, don't forget that stationary gas detectors are permanently connected to the mains and also draw electricity all the time.
What are the features of a portable gas detector and what are its advantages and disadvantages?
You can always take portable gas detectors with you and use them in all areas of your flat or house.
Mobile gas detectors can be used in all rooms of your house. Therefore, in contrast to stationary gas detectors, you only need one device to test the gas level in all areas of your home. In addition, electricity costs are lower and batteries need to be changed less often, because mobile devices only measure at the push of a button and not permanently.
However, this does not guarantee permanent protection, as you have to actively check yourself whether the gas content in the air is too high. This is particularly dangerous in the case of odourless gases, which you would not even notice without measuring them. Compared to stationary gas detectors, the portable alternatives are often more expensive to buy.
Buying criteria: You can compare and evaluate gas detectors based on these factors
Even if it doesn't seem like it at first, there are a few things you should consider and think about before buying a gas detector. The criteria you can use to compare gas detectors with each other are:
Where are gas detectors installed?
What to do if the gas detector gives a false alarm?
If your gas detector beeps and you suspect a false alarm, you should act as you would in an emergency.
If you have followed the installation instructions carefully, false alarms are very unlikely. So if the gas detector goes off, proceed exactly as you would in an emergency, even if you suspect a false alarm. If it turns out that the alarm system has given a false alarm, you will not have to pay the costs of the fire brigade or the emergency services, because the emergency call is justified. So it's better to be safe than to misjudge the situation.
Maintaining gas detectors correctly
To be sure that your gas detector will continue to work properly for several years, you should test it every month to see if everything is still working properly. To do this, simply press the test button on your detector. It will then sound an alarm to show that everything is still working properly. Many of the devices also have a small light to indicate that the gas detector is working properly.
Also make sure that you wipe your gas detector with a damp cloth once or twice a month. Otherwise, dust and dirt can affect the sensor's measurements.
