The gas analysis procedure is needed in various fields where you need to know about the composition and characteristics of air-fuel mixtures. At home, it is conducted to detect leaks. The environment can be not only a domestic gas pipeline, but also an air conditioning system with freon, a boiler plant. The household gas analyzer exists in various versions. They have different operating principles, control systems, characteristics. For home safety, such a device must be located.
Instrument Features
The device has specific characteristics, because it is intended for a special security industry - gas leak detection. Among the variety of devices there is equipment with various functions. The household carbon monoxide gas analyzer has small parameters, modest performance and simple operation. If professional appliances are operated stationary, then household appliances can move around. The main function of a gas analyzer is leak detection in the study of gas vapors.
Home appliances have different functions. For example, an inexpensive household gas analyzer has a simple warning system. This function can occur in the form of light or sound indication. If the concentration of gas vapors is increased in the apartment, the device will give a signal. Complex devices have displays on which detailed information is indicated. Thanks to them, convenient control is provided.
Types of Detectors
The household gas analyzer can be manual and automatic, which determines the convenience of work. In the first case, the device is presented in the form of an absorption apparatus that operates on the principle of absorption of gas vapors by reagents. Such devices are inexpensive and convenient to use. They show the average level of accuracy of the analysis.
Automated devices have a variety of features. They can function continuously, controlling the parameters of the mixture and its individual components. The basis includes physical analysis, chemical reactions, or a physicochemical process. Such parameters as pressure, mixture volume, and oxide concentration are set in the automatic detector.
There is a portable gas analyzer that has small parameters. It is convenient to use, easy to configure. Any types of leaks will immediately be noticeable. The portable gas analyzer is ideal for all rooms. Its functions do not differ from the standard device.
Installation Features
The household gas analyzer can be stationary, so it must be installed. It has compact dimensions, convenient maintenance and low performance. Install such a device in the area of high risk of gas leakage. This can be a place with a boiler installation, a stove or a boiler.
Mounting takes place on the wall so that users have access to control. Fixing is performed by the mounting profile, which is included. With screws or self-tapping screws, you need to install the supporting panel, and then the device itself is attached. Sometimes a power cable is required, but many low-power devices run on batteries. There are various household gas analyzers for apartments with gas stoves. Each of them has its own characteristics. Before using the device, you must familiarize yourself with the operating rules. There is an instruction manual for this.
Subtleties of operation
It is necessary to start work with the definition of the mixtures with which the device will work. Many instruments can function with sensors to track different mixtures. The main setting is to determine the level of gas concentration.
Of great importance is the diagnosis of the device. Every six months, it is necessary to carry out an instrument check. The procedure consists in examining the gas analyzer with a test of its working qualities. Be sure to control metrological characteristics that determine the accuracy of the values.
Verification is carried out by transferring the device to a special mode, after which the sensors do their job. Then, the readings are verified with the norm. A calibration that may be performed automatically may be required.
Foreign manufacturers
There is a household gas analyzer with a gas cut-off device, which is very convenient to use in comparison with standard devices. Specialized firms produce devices. The best ones are:
- Rothenberger;
- CEM;
- Testo;
- Mastech.
Russian manufacturers. Prices
Megeon devices are popular on the Russian market. Detectors also differ in cost, which is determined by various characteristics. A conventional gas analyzer with a small set of functions costs about 2-3 thousand rubles. If there is a display, then the device has a cost in the range of 5-7 thousand rubles. Multifunctional devices have a price tag of 15-20 thousand rubles.
When choosing a device, the type of test gases must be taken into account. Devices can work with combustible gases, for example, butane, natural gas. The detector can only be configured for one substance. It should correspond to the purpose - search for leaks and analysis of exhausts.
It is important to pay attention to the temperature range. If you work outdoors, you should choose a device that can withstand temperatures up to -20 degrees. Now gas analyzers for boiler rooms, laboratories and production are on sale.
Detectors that can be used to detect gas leaks are high-quality security systems. In conventional signaling circuits, these devices are included in the control center. It turns out that the device can automatically adjust to different conditions. In a separate mode, the detectors can be programmed. But the complex security systems work more extensively, since the controller manages the analyzer parameters using many different sensors and sensors.
