The Best Carbon Monoxide (CO) Detectors

Today’s realities are such that everywhere there may be an excess of carbon monoxide levels. Almost all of us live as if on a powder keg, you don’t know where and when it can explode. The news is scary. To protect yourself as much as possible, to gain peace of mind, it is worth installing a gas leak detector. Our article will detail the ranking of the best gas leak detectors for 2022.

The principle of operation of sensors

The operation of gas alarms can be divided into two parts. The first is to fix the critical indicators of gas contamination in an apartment or other room. The sensitive elements with which the device is equipped are responsible for this task. It turns out that the sensor works like a device for taking in and passing air through itself. It becomes an analyzer of the air environment and, if an increased concentration of toxic substances is detected, to which the sensitive elements are oriented, then an alarm is triggered.

The second part is to inform the owner of the detection of a critical gas concentration. Some devices are equipped with special communication channels, for example, the owner of the premises receives an SMS on his phone.

What are carbon monoxide sensors?

Now the market sells different gas leak detectors, they are divided according to the principle of operation, the type of sensitive element and the type of gas detected (carbon monoxide, carbon dioxide and natural). According to the principle of operation, it means that there are wired devices that connect to a 220-volt network, and there are wireless devices. Their functioning depends on the battery, which is very convenient when the electricity is turned off in the house.

There are three types of sensing element: semiconductor, catalytic and infrared. The most inexpensive ones are with a semiconductor element, they are most often bought by ordinary property owners. Catalytic analyzers are used in large enterprises in industry, their action is based on the combustion of gas and its decomposition into carbon dioxide and water. Infrared devices pass the gas through their beams and determine the excess concentration with extreme accuracy.

Where to install in the apartment

Gas leak detectors are installed in the apartment at certain points, which depend on the type of gas being detected. So, if you have a natural gas detector, then it should be placed in the upper zone of the apartment, retreating about 30 cm from the ceiling. During distribution, carbon monoxide fills the entire room evenly, so it is convenient to place the sensor for its determination at the level of human growth, that is, about one and a half meters and above from the floor.

General recommendations for installing sensors include the following tips:

  • Signaling devices should be placed near gas equipment;
  • In no case should you install signaling devices in a place where there is no air circulation (dead zones, behind cabinets);
  • If there is ventilation nearby, then the sensors are not placed next to it;
  • Do not install near windows, above the stove, with heaters and where there are sources of fire.

Conclusion

Having chosen the right gas leak detector, remember that once a year you need an inspection from a special organization. This office should make a metrological verification of sensors. This is done to ensure safety, to make sure that the equipment is working and working properly. Keep an eye on the sensitive element, it has its own expiration date, which is indicated by the manufacturer, and when it runs out, a replacement is required. The gas leak detector must be kept clean and free from accumulation of dust, ash, soot and other debris. Gently go over with a damp cloth, avoiding damage.

A well-chosen and correctly installed sensor will provide you with peace of mind and remove anxiety. So, taking care of such a sensor is beneficial not only for security purposes, but also for peace of mind.
