Gas or any man-made air mixture that is used in modern industries can pose a serious danger to human health and life. In the event of a gas leak, it is important to immediately identify the presence of a problem and quickly solve it. To achieve these goals, special devices have been created - gas detectors. Their types, features, tips for choosing and more - read below in the article.
How to choose a gas leak detector for your home?
When choosing a gas analyzer device for an apartment or a private house, you should pay attention to several important parameters:
- Dimensions. It is important to place the machine close to the place where there may be a malfunction and leakage. When buying, it is worth correlating the size of a stationary gas analyzer and the area of u200bu200bthe place where it will be installed
- Food. These devices can work both from the battery and from the mains
- Versatility. The more breakdowns and types of gases the device can recognize, the better
- The presence of additional functionality. More expensive models of household gas analyzers can shut off the gas supply from the main
When choosing, you should take into account such nuances: what is the device’s response threshold and operating temperature range, what gas does it react to, and whether the model has a gas shut-off valve.
What types of gas analyzers exist?
Depending on the type of construction, devices are divided into 3 large groups:
- Portable. They are small in size and weight, which makes them suitable for use anywhere. Are equipped with digital indication of the received results. Portable analyzers are often used to determine oxygen deficiency in underground facilities and confined spaces
- Portable (there are individual and personal). Used to control hazards at a person's location. Companies purchase such devices in situations where work personnel regularly perform work in potentially hazardous areas
- Stationary. Installed in a specific place, have large dimensions. Portable gas detectors are subject to increased requirements for reliability and stability of the readings taken
There is also a classification of devices for gas analysis according to the type of functions implemented:
- Gas analyzers — have the widest functional base, as they give not only a quantitative assessment concentration of substances, but also digital indication of results. Devices can also get additional features
- Indicators - serve only to provide a qualitative assessment of the gas mixture for the presence of a certain element in its composition
- Signalers - provide an opportunity to approximately estimate the concentration of substances, while using 1 or more alarm thresholds
Classification of gas detectors by the number of channels
Gas analyzers are single-channel and multi-channel.
Single-channel mechanisms have only one sensor in their design, so they are used to analyze the concentration of only one substance. Stationary detectors gas with 1 working channel can function both as part of a full-fledged measuring system, and and offline.
Multichannel detectors are capable of simultaneously monitoring up to 16 measurement channels. Due to the advanced functionality, these gas detectors are able to measure different types of gases. Multi-channel devices are often equipped with special gas distributors: they regulate the sequential supply of samples to the sensor, using more than 2 sampling points.
