What is the Best Methane Gas Leak Detector?

There are several excellent choices for a methane gas leak detector for the home. They may include the following:

What is Methane Gas?

Methane gas is both colorless and odorless. It is produced in both nature and human industrial activities, such as in the extraction of natural gas. It is composed of the molecule CH4 that is combustible and a frequent greenhouse gas contributor. Methane gas, is also known as natural gas and a very important fossil fuel source for the home (oven and cooktop) and business.

Is Methane Gas the Same as Natural Gas?

Yes and No.

Methane gas is not technically the same as natural gas but natural gas, mostly is composed on methane, along with other gases such as ethane, propane, carbon dioxide, and water vapor. But the main consistent gas in natural gas is methane.

Is Methane Gas Dangerous?


High concentrations of methane gas can produce dangerous health symptoms in homeowners and others who come into contact with it. Additionally, methane gas leaks have the potential to cause hazardous and deadly explosions that have been documented in the past.

What are Methane Gas Leak Symptoms?

Methane gas leaks can produce a number of symptoms in those who inhale high concentrations, thereby displacing oxygen in the body. Such symptoms may include, Increase in heart rate, Rapid breathing, Dizziness, Decrease in alertness, Weakness, Nausea, Convulsions, Coma, and Death.

Is There a Home Test for Methane Gas?


The best way to test for methane gas in the home is to purchase a methane gas detector and, for monitoring methane gas at all times, homeowners should look to purchase a fixed gas detector that has the capacity to be mounted to a wall.

What is a Methane Gas Leak Detector?

Personal Protection Methane Natural Gas Leak Detector

These are devices made to be fixed to your man, clipped to your shirt or belt and will alarm if methane levels are too high. These devices are often used by employees working in the oil and gas industry or where methane is used in an industrial setting.

How Much Does a Methane Natural Gas Leak Detector Cost?

In general, a natural gas leak detector or methane gas leak detector may cost anywhere between $50 and $300, depending on the quality of the device and its total capabilities.

Have There Been Any Explosions from Methane Natural Gas Leaks?

Yes. In fact, there have been a number of explosions caused by methane gas leaks. Some examples include the following:

  • In 2020, investigators suspected that methane gas leak had caused the explosion of a home in Signal Hill.
  • In 2018, a methane gas leak explosion at a fracking site in Ohio ultimately led to the evacuation of a number of individuals residing in a 1-mile radius of the explosion.
  • In 2019, a methane gas leak explosion in a sewer caused a car fire and caused people to flee the scene in the French Quarter.

How Does a Methane Natural Gas Leak Detector Work?

Methane gas leak detectors function by monitoring the level and concentration of methane gas in a given environment. Once the detectors monitors a level of gas that is higher that what it is programmed to deem normal, it alerts the user of the unusually high presence of gas.

How Do I Use a Methane Natural Gas Leak Detector?

With a mounted methane gas leak detector, homeowners should take care to mount the devices in an appropriate area closer to the ceiling for best results. With a natural gas sniffer, homeowners should properly get the device running before using the nozzle to identify a gas leak in an environment where a methane gas leak is suspected.

How Do You Detect a Methane Natural Gas Leak?

There are a number of methods to detect a methane gas leak, however the most effective and proper method is to use a methane detector or a combustibles detector. Other less effective methods include observing a sulfur/rotten egg smell, hearing a whistling/hissing noise, checking the stove, or conducting a soapy water test.

How Long Do Methane Natural Gas Leak Detectors Last?

Many methane detectors and natural gas detectors are capable of lasting for five or more years. As such, homeowners and landlords should be sure to replace them as needed so that the devices can continue to do their job as they are designed to do so.

Is a Methane Gas Leak Detector the Same as a Combustible Gas Leak Detector?

In most cases, yes.

A combustible gas leak detector is used to monitor the presence of a variety of combustible gases, including methane. However, these devices are not specifically tailored to methane gas detection. On the other hand, a methane gas leak detector is specifically tailored to methane gas detection, but may not be able to detect other combustible gases.

Due to the distinctions between these two gas sensors, it is imperative that homeowners looking to purchase a gas leak detector read the specs for each device. This will ensure that a detector that detects the desired gas is purchased.

Who Uses a Methane Gas Leak Detector?

Some typical users of gas leak detectors include:

Home Owners and Landlords

Homeowners and landlords may find need for a methane detector if they own appliances or suspect gas leaks from pipes or connections. A gas leak detector would be a useful tool to pin point suspected gas leaks.

Plumbers, Technicians, HVAC, and Other Professionals

Professionals including plumbers, engineers, technicians, HVAC technicians, and more may come into contact with methane gas, so combustible gas leak detectors can help them find methane gas leaks.

Livestock Owners and Agricultural Workers

Livestock owners and agricultural workers frequently work in operations that have the potential to release methane gas into the environment.

Business and Workplace

Many businesses such as restaurants have natural gas burning appliances, cooktops, ovens and heaters. Gas leaks are common especially in location that are old and aged.

Do I Need a Methane Gas Leak Detector?

Maybe. If you have a gas leak, and want to confirm its location, a gas leak detector may be appropriate. Calling a plumber or your gas company is also a option.

If you are a homeowner or other professional who has the potential to use and come into contact with methane gas, yes.

Can a Carbon Monoxide Detector Detect a Gas Leak?

No, a carbon monoxide detector will not detect a gas leak.

These detectors are specifically designed to sense carbon monoxide (CO), a colorless, odorless gas produced by burning fuel. Gas leaks, usually involving natural gas or propane, primarily consist of methane, which carbon monoxide detectors are not equipped to detect. For detecting gas leaks, a specific gas leak detector is required.

Can a Gas Leak Detector detect a Carbon Monoxide Leak?

No, a gas leak detector will not detect a carbon monoxide leak.

Gas leak detectors are specifically designed to identify combustible gases like natural gas or propane, which are different from carbon monoxide (CO). Carbon monoxide is a byproduct of incomplete combustion and requires a dedicated carbon monoxide detector to be sensed, due to its different chemical properties and dangers.

Will a CO2 Detector Detect a Gas Leak?

No, a CO2 detector will not detect a gas leak.

CO2 detectors are designed to measure levels of carbon dioxide (CO2), which is different from combustible gases like methane or propane typically involved in gas leaks. Gas leaks require specific detectors that can sense these flammable gases, as they pose different risks and have different properties than carbon dioxide.

Where Should a Methane Gas Leak Detector be Located?

A methane gas leak detector should be located close to the ceiling if it is meant to be mounted for a sustained duration of time. This is because methane gas is lighter than air, so it will sit above the air and thus be present closer to the ceiling than the floor.

For locating gas leaks using a gooseneck like gas leak detector, place the sensor along suspected locations and run it slowly around different locations. Cross-winds, ventilation and turbulence effects all play a critical role in dilution physics, which will impact the speed of detection. Hence, the importance in obtaining a gas leak methane detector that reads parts per million resolution.

Will a Methane Gas Leak Detector Detect Natural Gas?


Natural gas is mostly composed of methane gas. Other combustible gases are also included, therefore a gas leak detector using a pellister sensor or non-specific semiconducting oxide material will detect all combustibles within the natural gas.

How Do I Select a Methane Gas Leak Detector?

To purchase a methane gas leak detector, there are several factors that are particularly important to research.

Length of Time it Will Last
  • Different detectors possess varying battery life lengths.
  • The expiration dates of devices can vary, typically with most falling between 5 and 10 years.
Gas Type
  • Different detectors have the capacity to detect different types of gases.
  • Typically, the more gases a detector is able to monitor, the more expensive the device becomes. This is not true for all devices, however.
  • Greater sensitivity is preferred, as this will allow a more accurate reading of the presence and location of methane gas. Ensure your gas leak detector has part per million sensitivity - and not just %LEL.

What do Customers say?

The FD-91 is our most advanced gas leak detector. This is a true story from an customer:

Reviewed in the United States on July 23, 2022

I purchased this because we smelled gas in the basement, but PSE&G could not detect it with their meter. I calibrated it and it was detecting gas *everywhere* inside. That made me skeptical, so I put it to the stove burner (running but not lit) and it pegged high. I put it outside and it went back to zero. So I felt like it was working.

After checking the whole house, I isolated the highest readings to the gas water heater. I did not see the pilot tube corrosion because it was under the tube not on top. I called PSEG again, another guy shows up and commented the Forensics meter is "too sensitive to be useful".

Well again, his meter didn't pick up anything in the house. I bring him to the water heater and his meter is STILL not getting anything (!). I showed him 2 places I was getting very high readings, the thermostat and the exhaust up top. After like 10 minutes, he visually locates the corroded pilot tube . Long story short it got fixed and now my Forensics meter reads ZERO all around the house including the water heater. Despite my concern it was accurate the whole time.

I have decades of experience with high-end electronic test equipment. My expectations were low for this being only $100. But this meter proved itself against the big boys, it may not read the exact PPM, but it's a useful relative indicator and you can trace a leak with it. I'm sure this will come in handy again.

TIP 1- based on the reviews of people breaking it, I am VERY careful with it. It's weighted kind of awkward due to the top heavy sensor so just treat it like it's a Champaign glass. I carry it from the tube so it's balanced.

TIP 2- make sure you calibrate it outside where there's zero gas

TIP 3- natural gas rises and it's shocking how much that tiny leak filled the house with detectable gas! Do not be surprised if you get readings far away from the source of the leak!

Final Words

Methane gas leak detectors (also called combustible/natural gas detectors or sniffers) provide vital monitoring against this insidious home hazard. Methane leaks pose serious risks like health issues and explosive dangers, making early detection crucial. Fortunately, these relatively inexpensive instruments offer reliable, continuous sampling to identify leaks before hazardous buildup occurs. With 5-10 year lifetimes, methane detectors are a smart investment for homeowners and landlords seeking optimal safety. From residential properties to industrial gas applications, dedicated methane monitoring equipment is essential for mitigating potential catastrophes. Don't overlook this invisible threat - implement methane leak detection for peace of mind and protection against gas-related incidents.
