The leak sensor carbon monoxide: why you need it

The auxiliary heating your own home is not only very convenient but also potentially dangerous. In the combustion process of any fuel stands out carbon monoxide, or carbon monoxide, are extremely dangerous to living organisms. In small concentrations it causes drowsiness and slight malaise. If the quantity of carbon monoxide in the air exceeds 1.2%, death occurs within three minutes.

A particular danger of carbon monoxide is that it is odorless and tasteless. A person does not feel his presence as long as his health begins to deteriorate rapidly. Practice shows that the carbon monoxide concentration in the room increases, mainly due to leaks from a faulty chimney, problems with ventilation and similar reasons.

To prevent a dangerous situation, experts strongly recommend the use of a special device – a leak sensor carbon monoxide. The device continuously analyzes the chemical composition of the air in the room and if the concentration of carbon monoxide reaches dangerous levels, an alarm signal. The equipment can recognize and availability of domestic gas, which is very important for owners of gas equipment.

There are several varieties of these sensors. A detailed look at the most effective of them.

Twenty five million three hundred sixty four thousand two hundred eighty eight



Infrared detectorSuch analyzers are miniature devices universal using for its operation non-dispersive infrared method of determining the concentration of the substance. It is the analysis of the wave spectrum of air, which is subjected to IR irradiation. This way you can determine the presence and quantity of any known gas. The detector is programmed to detect a dangerous concentration of a certain substance.

Infrared analyzers — perhaps the best of the devices that you can now find on the market. They are very compact, stable and does not depend on the concentration of oxygen in the air. Device polling can respond not only to carbon monoxide and other gases. The detectors feature high sensitivity and fast response, while the recovery time of the device is small.

IR analyzers are reliable and have long life. They are volatile and are working from the network, but there are modifications, operating from batteries. Sensors are among the latest developments with a modern microprocessor-based circuitry. Domestic models of IR detectors not yet common, and their cost is relatively high.

Sixty two million four hundred thirty nine thousand eight hundred five



Semiconductor analyzersFor the operation of devices uses the principle of interaction of atoms of various substances. As a sensitive material selected highly dioxides. They are distinguished by low conductivity under condition of presence of clean air. Once in the analyzed environment appears carbon monoxide, the conductivity of the sensor begins to grow. The higher the concentration of hazardous gas, the higher the conductivity of the device. This relationship locks the Converter that activates and if necessary an acoustic signal. Depending on what substance is chosen as the active, solid-state analyzers can react to different gases.

In General, the detectors features high sensitivity and stable performance. Practice shows that such sensors are almost never false positives. The response time is higher than its competitors, which is considered a major disadvantage.

In addition, semiconductor detectors are very compact and are characterized by long service life. Their connection is extremely simple and the cost low. The only drawback of the device can be regarded as the necessity of his work directly from the mains. Varieties of the detector with the battery or batteries are not available.

Ninety seven million forty nine thousand five hundred twenty nine



Electrochemical sensorAnalyzers of this type are used for the electrochemical catalytic reaction. They include a capsule with a conductive electrolyte and electrodes, necessary for carrying out such a reaction. Air from the room enters the analyzer, which takes place a redox reaction. In the presence of carbon monoxide, the number of free ions increases, the reaction rate increases. The signal generated by the electrochemical analyzer is changed. To achieve a dangerous level of concentration of carbon monoxide is activated by sound alert.

The advantage of these detectors is a small power that allows them to work from batteries of the rechargeable type. There are two types of devices: a galvanic cell filled with alkali, and acid element. The first option is less durable and is exposed to foreign molecules. Galvanic capsules filled with acid, devoid of these shortcomings. The manufacturer produces practical modification of the analyzers with model cells, which significantly extends the service life of the instrument. The detectors are distinguished by fast response, stable operation and low cost.

Five million nine hundred nine thousand six hundred eighty



Regardless of the variety of gas analyzers are equipped with special self-test function. In the event of a malfunction the unit will emit a special signal. It is very important to correctly choose the place for installation of the detector and to correctly put it. The only way he will be able to fully perform its functions and to timely warn the owner about the hazardous situation. published
