Best gas leak detectors for 2020

Today's realities are such that carbon monoxide levels can be exceeded everywhere. Almost all of us live as if on a powder keg, you do not know where and when it might burst. The news is scary. To maximize your safety and peace of mind, you should install a gas leak sensor. Our article will detail the ranking of the best gas leak sensors for 2020.

Operating principle

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

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

What are

Now on the market there are different gas leak detectors sold, they are divided according to the principle of operation, by the type of the sensitive element and by the type of gas detected (carbon monoxide, carbon dioxide and natural). By 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.

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

Where to put in the apartment

Gas leakage alarms are installed in an apartment at certain points, which depend on the type of gas being detected. So, if you have a natural gas detector, then it must be placed in the upper area of ​​the apartment, retreating about 30 cm from the ceiling. During its spread, carbon monoxide fills the entire room evenly, so it is convenient to place the sensor for its determination at the level of human height, that is, about one and a half meters or more from the floor.

General recommendations for installing sensors include the following tips:

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

Conclusion

When choosing a suitable gas leak detector, remember that an inspection from a specialized organization is required once a year. This office should do 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 ends, a replacement is required. The gas leak detector must be kept clean and free from dust, ash, soot and other debris. Wipe gently 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 safety reasons, but also for the sake of peace of mind.
