إذا طلبت منا أن تقوم أجهزة كشف أول أكسيد الكربون بالكشف عن الغاز الطبيعي, سنقول بالتأكيد لا. في النص التالي, we will look into the reason steps by steps and offer some useful suggests.
Why CO Alarms Cannot Detect Natural Gas?
What Is Carbon Monoxide?
أول أكسيد الكربون هو عديم اللون, عديم الرائحة, non-irritating toxic gas. Its chemical formula is CO. It is produced by incomplete combustion of carbon-containing fuels, such as coal burning. When large amounts of carbon monoxide enter the human body, it binds to hemoglobin to form carboxyhemoglobin and reduces the ability of hemoglobin to carry oxygen. So carbon monoxide is a dangerous gas.
What Is Natural Gas?
Natural gas mainly contains methane (CH₄), which is above 85%. And, it contains a small amount of hydrocarbon gases, carbon dioxide (CO₂), nitrogen (N₂), hydrogen sulfide (H₂S), and very little carbon monoxide (CO). بجانب, it also has trace amounts of rare gases, such as helium (He) and argon (Ar). Once it leaks, it immediately spreads upward. Compared to CO, natural gas is relatively safe because it seldom accumulate to form explosive gases.
Carbon Monoxide vs. Natural Gas
| Carbon Monoxide | Natural Gas | |
| Chemical Formula & Molecular Weight | CO, with a molecular weight of 28.0101 | Primarily methane (CH₄), molecular weight varies based on composition |
| Physical State | Normally a colorless, عديم الرائحة, tasteless gas | Colorless, عديم الرائحة, non-toxic gas, gaseous at standard temperature and pressure |
| Toxicity | Toxic. It cause poisoning symptoms of human body at higher concentrations. | Non-toxic. Its combustion brings carbon dioxide, a greenhouse gas. |
| Combustibility | Combustible. It produces carbon with a blue flame dioxide when burned. | Stable combustion. It releases few pollutants |
| Application | Used in the production of sodium formate. Act as a reducing agent in metallurgical industries. Use in house as a gaseous fuel. | Widely used for heating, cooking, power generation. Sometimes it acts as a chemical raw material. |
| Safety | Highly hazardous, easily binds with hemoglobin causing tissue hypoxia in humans | Relatively safe. But high accumulation may leads to explosion and fire. |
| Sources | Produced during incomplete combustion of carbon-containing fuels | Formed over millions of years from ancient organisms buried underground under high temperatures and pressures. |
What Does A Natural Gas Detector Do?
The gas detector can continuously monitor the concentration of natural gas in the surrounding environment via the principle of electrochemistry or catalytic combustion. When the detected concentration of natural gas exceeds the preset safety range, it will issue an alarm or light prompt to remind people of taking safety measures in time. It greatly helps to detect potential leakage risks in time.
What Does A Carbon Monoxide Detector Do?
The working principle of carbon monoxide detectors is usually chemical sensors or electrochemical sensors. These sensors are able to sensitively detect the presence of carbon monoxide gas and convert it into an electrical signal for measurement. It will send an alert when carbon monoxide levels reach dangerous levels. بهذه الطريقة, people can respond to carbon monoxide leaks in time.
So Carbon Monoxide Detectors Do Not Detect Natural Gas
Carbon monoxide and natural gas are two different gases with different chemical properties and hazards. This calls for different detection devices and detection methods. Carbon monoxide detectors usually use chemical or electrochemical sensors to detect the concentration of carbon monoxide, while natural gas detectors usually use a combustible gas sensor. لذلك, carbon monoxide detectors cannot be used to detect natural gas.
Does Carbon Monoxide Still Play A Crucial Role At Home?
Although it cannot detect natural gas, carbon monoxide detectors still play a vital role in the home. Carbon monoxide detectors focus on detecting carbon monoxide, a toxic gas, while natural gas detectors focus on detecting leaks of flammable gases. لذلك, each plays an indispensable role in the home.
أول أكسيد الكربون هو عديم اللون, عديم الرائحة, non-irritating toxic gas. It isn’t easy for human senses to detect directly. Accordingly, carbon monoxide sensors can monitor the concentration of carbon monoxide in the indoor air in real-time and issue timely alerts when the concentration exceeds the standard. This effectively protects people’s health and safety.
Alternative Ways for Detecting Natural Gas
Do Not Use Your Sense of Smell to Sense Gas Alone
Natural gas itself is colorless and odorless. لكن, for easy detection by humans, household gas is odorized, which makes it smell like rotten eggs. لذلك, once a similar odor is detected in the home, there may be a natural gas leak. More and more, please note that this method is not suitable for people who are not sensitive to smell, such as the elderly and rhinitis patients. لذا, don’t just use smell to determine whether the gas is leaking.
Check Gas Meter
In the case of not using natural gas, we can observe whether the number in the red box at the end of the gas meter moves. If the numbers are moving, it could indicate a gas leak.
Soapy Water
We can mix soap with water to make soap liquid and then apply it to gas pipes and other places that are prone to air leakage. If there is a natural gas leak, the soap will be blown out of foam by the leaking natural gas. This method is simple and easy to use, but it is too unconspicuous to observe small leakage points.
Natural Gas Detector Is Helpful
This method is highly sensitive and timely to detect natural gas leaks. It is the prior method for detecting natural gas leaks at home.
Gas detectors can detect low concentrations of flammable gas in the surrounding environment through the gas sensor. When there is a gas leak , the gas alarm will send out an alarm signal. If your device comes with Wifi IoT technology, it can interact with smart exhaust fans and smart air purification systems. This will greatly prevent an explosion.

Frequently Asked Questions
Does A Carbon Monoxide Detector Detect Gas From the Stove?
Yes, but we can’t detect all the gas from the stove.
First, we need to understand what type of fuel our home stoves use. Frequently-used fuels are natural gas, LPG, wood, coal. The combustion of these fuels produces carbon monoxide gas and other gases listed below.
| Fuel of Stove | Gas From the Stove |
| Natural Gas | مethane, CO2, vapour |
| LPG | Propane, butane, CO2, water vapor, CO, hydrocarbons, nitrogen oxides |
| Wood | CO2, water vapor, nitrogen oxides, CO |
| Coal | CO2, sulfur dioxide, nitrogen oxides, CO |
It is recommended to prepare a corresponding all-in-one gas detector according to the fuel type of your stove.
Do Carbon Monoxide Detectors Detector Propane?
No. If you have a propane-fueled gas stove at home, you can prepare an all-in-one gas detector.
How to Install and Maintain the Gas Detector
We set up gas detectors in areas where there may be gas leaks. If the specific gravity of the gas is less than air, the detector should be installed at a distance of 30~60 cm from the ceiling. Then, we use screws to securely attach the detector to the wall.
Hardwired type device generally comes with three-wire transmission, including positive power supply, signal line and negative power supply. We can prepare highly shielded lines to avoid interference with electrical signals. Next, we open the cover and connect the corresponding terminal to the channel module. After the wire is connected, we restore the cover.
We should inspect the device after six months to one year. If the sensor of the gas detector loses its sensitivity, we should replace it.
