best natural gas detectors

So how could we detect the gas leakage if any for a safety purpose? It is a device which is used to detect the leakage/ presence of any gas in the area as a part of the safety device and alert with any leakage in kitchen or office.

A gas detector notifies the presence of gas with an alarm sound which is helpful to avoid any hazardous situation. So, as a safety feature, we can use the gas detectors for USA or in any such area where the gas leakage detection is necessary.

It can also be used to detect combustible, flammable and toxic gases which might put in a situation. So let see what options of lpg leak detector for home we have for you in store.

10+ Natural gas leak detector reviews

Gas detectors measure and indicate the concentration of certain gases in the air with some technology. Most of the gas detectors are battery operated devices. They can be portable or fixed.

Previously gas detectors used to detect one type of gas at the time but, with improvement in technology new gas detectors can detect multiple types of gases at a time.

Now how a detector concludes that there is a gas leak? So, the gas detector measures a specified gas concentration, the sensor response in the gas detector serves as the reference point or scale.

When the sensor response surpasses certain predefined level in the gas detector then the alarm sound is activated to notify the user.

We can see various types of gas detectors in the market for different purposes related to location. So, below we can see some important points by analysing which we can find out to choose the top portable gas detector.

Gas Detector Technology

The first thing you should see on which technology the gas detector is operating. They can also be categorised on which gas they are detecting. We can see the catalytic and infrared sensor based combustible gases. Electrochemical and metal oxide semiconductor technology based detectors detect toxic gases.

User Maintenance

We can check how much maintenance is required for a particular gas detector model. So if the maintenance requirement is feasible for you then you can go ahead with buying that particular model which you liked.


Calibration of a gas leak should always be verified while buying any particular model. Calibration is a safety procedure executed to endure that the detector is measuring the level of gas.

Frequent calibration of a gas leakage detector is necessary as contaminated sensors may not register the dangerous gas level. The life-span of a detector is depending upon the number of gas vapours it is exposed to that’s why frequent calibration of a gas detector is important.


Price is also an important factor while buying any detector for gas leak for kitchen. Though, lpg gas detector price is important but for a safety precaution quality of a product should not be compromised while buying gas detectors.

But if you are getting all the features with a good price then you should definitely go for buying that particular gas detector model.

Features to Consider When Purchasing a Gas Leak Detector

  • Is there an integrated light system in your gas leak detector?

A light detector plays a vital role in detecting a gas leak. Often the noise alarm created is not enough as the elderly people who suffer from hearing problems might miss the signal. In such a scenario, an integrated light system comes handy. You can choose the colour of the detector as per your convenience. 

  • Probe length & flexibility

You must also consider the range of the probe which has been included. The flexibility of the detectors also plays a significant role in choosing a gas leak detector. 

  • Parts per million (PPM) sensitivity

Always evaluate the specifications of the gas detectors before deciding to buy one. Ensure that you are purchasing a detector which has the requisite sensitivity to cater to your needs. The gas detector’s sensitivity depends on the sensor that is used in it. 

  • Automatic calibration

See to it whether or not your gas detector has an automatic calibration. This will enable the detector to perform effectively.

  • Audio and visual warning systems

Make sure your gas detector has proper audio and visual warning system or else you will never be able to find out when there’s a leak, and the whole purpose of having a gas detector goes in vain. Some of the detectors are also provided with a headphone jack so that you can also hear the buzzers directly on your headphone. These buzzers can be muted as well.

  • Auto power-off

Choose a gas leak detector that comes with auto turn off feature. These detectors turn off after a fixed period of time thereby saving the battery from getting drained. 

  • Warranty

Check whether or not the gas detector comes with a proper guarantee and warranty. In case your product doesn’t function well, you can always return it back to the company and get a replacement or a refund. 



  • What should I do once the gas detector has detected a gas leak?


In the event of a gas leak, be it carbon monoxide or any other combustible gas, gather your family and go outside of your house at once. Once outside, use your cell phone to immediately call the local fire station. They will soon arrive at your home in their protective wears and check for the source of the leak.  They will also help you reach a remedy to your problem. Until, they haven’t declared your home as safe, do not enter your home. 


  • Isn’t there a way to check for leaks using soap bubbles?


The soap bubble technique has become quite old and it is not reliable enough to judge such a serious issue. In this technique, a mixture of soap and water solution is prepared and is sprayed over the potential gas leak area. If there is any gas leak, bubbles will start to form thereby making it easy to detect the leak area. 

This method is quite tricky as you might end up spraying soap all over yourself. A much smarter option is to install a gas detector. It will save you from so much trouble. 


  • Can I use a handheld gas leak detector?


Yes, you can. Though gas leak detectors might look like gadgets that use rocket science, but they really aren’t that difficult to handle! You can think of them as a way of playing hot and cold. They turn red when brought near the area of susceptible gas leak, followed by a beep or ticking sound. 

  • Do all gas leak detectors detect carbon monoxide?

No. The handheld gas detectors are mainly made to detect carbon monoxide. However, some of the other gas detectors are capable of detecting combustible gases like the natural gas. Make sure you read the specifications properly before you end up purchasing one.
