How to choose a household gas analyzer: reviews about manufacturers. Gas analyzer for home acquisition of the gas supply sensor and the shut-off valve in the boiler room

Gas analysis procedure is needed in different areaswhere you need to know about the composition and characteristics of air combustible mixtures. At home, it is carried out to detect leaks. The medium may not only be a household gas pipeline, but also the air conditioning system with freon, boiler installation. Household gas analyzer exists in various versions. They have different principles Work, control systems, characteristics. For the safety of the house, such a device must be located.

Features of devices

The device has specific characteristics, because it is intended for a special branch of safety - the detection of gas leakage. Among the diversity of instruments there are equipment with various functions. Household gas analyzer has small parameters, modest working indicators and easy control. If professional devices are operating stationary, then household devices can move. The main function of the gas analyzer is considered to be a search for leaks in the study of gas vapor.

Home devices have different functions. For example, the inexpensive household gas analyzer has a simple alert system. This feature can appear as a 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 that are denoted by detailed information. Thanks to them, convenient management is provided.

Types of detectors

The household gas analyzer is manual and automatic, the ease of operation depends. In the first case, the device is presented in the form of an absorption apparatus, which works on the principle of absorption of gas vapor reagents. Such instruments inexpensive and easy to use. They show the average level of analysis accuracy.

Automatic devices have a variety of features. They can function continuously by controlling the parameters of the mixture and its separate components. The basis includes physical analysis, chemical reactions or physico-chemical process. In an automatic detector, parameters such as pressure, mixture volume, oxide concentration are installed.

There is a portable gas analyzer that has small parameters. It is easy 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 is stationary, so it must be installed. It has a compact size, convenient maintenance and low characteristics. Install such a device in the field of high risk of gas leakage. It may be a place with a boiler installation, kitchen stove or boiler.

Fastening takes place on the wall so that users have access to management. Fixing is performed by the fastening profile, which is included. Scuffers or self-drawers need to install the carrier panel, and then the device itself is fastened. Sometimes the supply cable is required, but many low-power devices function from batteries. There are different household gas analyzers for apartments with gas plates. Each of them has its characteristics. Before using the device, you need to familiarize yourself with the rules of operation. To do this, the instrument has an instruction.

Subtleties of operation

It is necessary to start working with the determination of the mixtures with which the device will work. Many devices can function with sensitive elements on tracking different mixtures. The main setting is to determine the level of gas concentration.

The diagnostics of the device is of great importance. Every six months need to check the devices. The procedure consists in a survey of a gas analyzer with a test of its working qualities. Must be controlled that determine the error of values.

Checking is carried out by transferring the device to a special mode, after which the sensors perform their work. Then the testimony with the norm is accomplished. It may be necessary to calibrate, which is performed automatically.

Foreign manufacturers

There is a household gas analyzer with a gas supply device that is very convenient to use compared to standard devices. Devices are made by specialized firms. The best of them are:

• ROTHENBERGER;
• Testo;
• Mastech.

Russian manufacturers. Prices

On the russian market Popular devices of the brand "Megeon". At the cost of the detectors are also different, which is determined various characteristics. Normal with a small set of functions costs about 2-3 thousand rubles. If there is a display, 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, it is necessary to take into account the type of gases under study. Devices can work with for example, butane, natural gas. The detector can only be configured for one substance. It must correspond to the appointment - the search for the leaks and the analysis of exhausts.

It is important to pay attention to the temperature range. If you work on the street, you should choose the device withsting temperatures up to -20 degrees. Now gas analyzers for boiler rooms, laboratories and production are sold.

Detectors that can be used to determine gas leaks are high-quality security systems. In conventional alarm diagrams, these devices are included in the control. It turns out that the device can automatically adapt under different conditions. In a separate mode, detectors can be programmed. But in the security system, it is extensive, since the controller controls the analyzer parameters using many different sensors and sensors.

Gas analysis is required in various fields, where it is important to have an idea of \u200b\u200bthe composition and characteristics of air combustible mixtures. At home, gas analyzers, or detectors, are more often used to detect leaks. Moreover, the target environment may not only be a household gas pipeline. This may be the air conditioning system with freon, and the boiler installation with harmful emissions. Modern gas analyzer is presented in different versionswhich differ in the principle of work, control system, performance characteristics and other parameters.

Features of household gas analyzers

Models for home Application Different little sizes, modest working indicators and simplified management. If a professional devices suggest stationary operation, then household apparatus Provides the possibility of moving. Its functionality is designed to search for leaks with a survey of gas vapors in different points. At the same time, in the segment of domestic apparatus exist different levels Functional filling. For example, the gas analyzer of the household from the budget category works with simplest system Alerts that can be represented by light or sound indication. That is, if the apartment has an excess of the concentration of gas vapor relatively regulatory valueThe detector will give an appropriate signal, but without for more information. More complex household models are equipped with a display, which reflects data from detailed characteristics The investigated environment.

Varieties of detector

Gas mixture home analyzers are presented in manual and automatic versions. In the first case, this is a simple absorption device, the principle of operation of which is based on the process of absorbing gas vapor reagents. This is inexpensive and at the same time available in the application of the device, which demonstrate the average level of accuracy of analysis. Automatic models are characterized by broader research capabilities of targeted environments. In particular, the gas analyzer of this type can track in continuous mode certain parameters Mixtures or a separate component. As for the principle of operation, it can be based on the principle of physical analysis, chemical reactions or physicochemical process. Using an automatic detector, the user determines such indicators such as the pressure and volume of the mixture, the concentration of the oxide, etc.

Installation of gas analyzers

In the family of household analytes, stationary models are also found, which suggest execution special Installation. At the same time, they are also characterized by compact sizes, unpretentiousness in service and low performance. Installation of such an instrument is usually performed in a place of increased danger. gas leakage. It can be a plot next to a boiler or kitchen stove. The mount is most often carried out on the wall so that the user remains the possibility of direct access to the control panel. A gas analyzer is fixed using a fastening profile, which usually goes in the base set. With the help of screws or screws, you must install the carrier panel, and the device itself is already integrated into it. Depending on the type of model, the supply cable can also be required from the power supply, although household low-power analyzers often operate from batteries and batteries.

Nuances of exploitation

Work begins with the determination of the mixtures to which the device will be oriented. Modern devices allow you to adjust sensitive elements to track different parameters of mixtures. Home Setup refers to the definition of the upper and lower level of gas concentration. Special attention during operation should be given to the diagnosis of the device. For about once every six months, the gas analyzers are verified, which is a comprehensive examination of the device with the test of its working qualities. IN obligatory It is estimated from which the error of the obtained values \u200b\u200bdepends. Typically, the calibration is performed through the translation of the device to the appropriate mode, after which the sensors are analyzed by test mixtures. Next, the obtained indicators obtained are performed. Depending on the obtained error data, calibration may be required, which is most often implemented in automatic mode.

Manufacturers and prices

Gas analyzers do not relate to widespread metrological devices, therefore, their development and production is mainly specialized companies. Rothenberger, Seztech, Testo and Mastech can be attributed to the best of them. In the Russian segment are popular for the quality of the model from the MEGEON line. For the price, the detectors differ significantly - it depends on the set of parameters. A simple gas analyzer for a home with a minimum set of functions may cost about 2-3 thousand rubles. The average for the possibilities of the device with the presence of the display is already estimated at 5-7 thousand. Multifunctional indicators with high-tech sensors can cost 15-20 thousand.

Conclusion

Detectors that serve to identify leaks and spills in residential buildingsare increasingly considered as components of integrated security systems. In classical alarm diagrams, such devices are entered into a single electrical engineering control point with the possibility of programming functions. This means that the gas analyzer can automatically adapt to work in specific conditions. It can be said that in a separate mode of operation, a modern automatic detector enables programming. But they expand these opportunities as the controller manages the analyzer parameters, guided by the data from many other sensors and sensors.

The installation of the device does not require the replacement of gas cranes and overlap of the highway. Put on any crane.

All device blocks are mounted separately and are connected to the wires, according to the electrical circuit.
The power supply is mounted with fasteners not far from electrical outlet (220V.) According to the rules of TB and PUE. The power supply has a power cable with a fork at the end, which is included in the outlet. The gas analyzer unit is mounted using a fitting indoor, where gas-grade equipment is installed (gas stove, fireplace, gas boiler).

• Recommended distance from Gas Plate 1 m. In any direction

Examination of premises for the identification of critical indicators gas mixes It is an important condition for ensuring security at the facility. We can talk about production sites, and rooms in apartments and private houses, where gas communications are used. Simple tool Such a survey is a household gas analyzer, which, depending on the version, can also perform a signaling device. The device may have different performance featuresWhat should be considered when choosing.

How is the gas analyzer?

Almost all models of such devices contain a converter in the design (detector), a measuring module and power supply. As for the converter, it can be functionally imagined as a sensitive element, which determines the presence of certain components of the mixture under study by sending the corresponding signal. This sensor can work differently depending on the principle of fixing chemicals.

In turn, the signal processing performs the measuring module. With its help, household gas analyzers for apartments do not simply register the fact of the presence of a certain concentration of one or another component, but also reflect specific values \u200b\u200bon the display. Anyway modern models The devices are allowed to display with the output of several parameters of the mixture.

To maintain autonomous and permanent performance in the design of the device, the aforementioned power supply is provided. It may be a compartment with AAA format batteries, and a battery. The main thing is that it allows the use of a gas analyzer even where there is no access to the outlet. Also there are stationary network models on 220 V.

Types of device

The models of gas detectors are distinguished by many signs - from the method of placement to the form factor and the extent of the same autonomy. But the principle and most important is the classification on the principle of the sensor. Based on this feature, the following types of household gas analyzers can be distinguished:

• Thermochemical. In this case, thermal radiation of the chemical reaction with the participation of the target component of the gas mixture is measured. Most often examined the process of oxidation with air catalysts.
• Magnetic. Such models are mainly focused on the detection of oxygen and determining its concentration. The principle of operation of the sensor is based on the dependence of the magnetic reaction to the level of oxygen content in the gas mixture. Magnetchanical and thermomechanical devices can be attributed to varieties of the device.
• Infrared. In the process of operation, the absorption of individual particles of gas vapor of IR radiation occurs. Depending on the wavelength and optical scheme, the analyzer can work with a point definition of concentration at the molecular level. different types Components consisting of several atoms.

Reviews about Testo models

From the point of view of functionality, accuracy and reliability of work, this is the most attractive line of gas analyzers. Testo products are highly appreciated by professionals, and ordinary users who use devices in the kitchen, in boiler room or other rooms, where there is a risk of increasing the concentration of harmful substances. For domestic needs, you can purchase a household gas analyzer in modification 310. The owners of this device separately emphasize the presence of a powerful battery, extended communication abilities (including a printer connection for data printing), a large display and the ability to automatically register the parameters. The design of the device also allows it to be installed directly in chimney or gas pipeline, tracking and pressure indicators in the circuit.

Reviews about the model CEM GD-3300

CEM manufacturer is a direct competitor Testo in the measuring instrument segment. But in this case it is appropriate to consider the entry-level gas analyzer. The GD-3300 model primarily attracts a low price tag at 3.5-4 thousand rubles. By its accuracy, it is a little inferior to the aforementioned version, and in terms of universality it is at all better options in its class. As the owners note, the device works effectively with natural gas, and with the determination of mixtures of butane, propane, ammonia, alcohol vapor, etc., positively characterize the owners and functionality of the model. If you organize a connection to the control relay in the circuit, then a full-fledged household gas analyzer is obtained with a mixing device. After detection of leakage, the device activates the visual and noise signaling, in parallel, sending the command to the control unit for the equipment control.

Rothenberger Model Reviews

Also notorious manufacturer measuring devicesfocused on detecting leaks and subsequent signaling. One of the basic modifications of the family is R087305. it electronic devicewhich is used in thermal circulation systems with mixtures, air conditioners and cooling circuits. The pluses of household gas gas analyzer from Rothenberger include high energy efficiency and ease of operation. For example, the rechargeable unit for 2.4 V allows you to use the device for 50 hours. As for minuses, many emphasize the narrow specialization of the apparatus and the impossibility of its use for whole groups of gas environments.
