Which production industries are gas detectors widely used in?
The current application field of gas detection technology is getting wider and wider. Not only is it required to be superior to other detection products in technology, but it is also gradually lighter in use and operation. The portable gas detector is too large and inconvenient to use. In order to facilitate Portable and easy to use, portable gas detectors are becoming more and more perfect. At present, portable gas detectors also have a clear classification, which is divided into two types: pump suction type and diffusion type.
Most sensors of gas detectors have their service life. Generally speaking, the life of electrochemical sensors is two to three years, the life of oxygen sensors is one to two years, the life of catalytic combustion sensors is about three years, infrared/semiconductor and photoion It takes about three to five years. At the same time, these parameters also have a great relationship with the use environment. The life of the sensor will be shortened to a certain extent when the environment concentration is continuously high or the environment where the alarm is often used.
Therefore, if you need to obtain higher selectivity of gas detection in actual analysis, or need to know the accurate concentration data of a certain gas, you must use the method of laboratory analysis instruments for the analysis of gas concentration measurement. There are many instruments, such as Fourier Transform Infrared Gas Chromatography and Mass Spectrometry, etc. These instruments can provide the most accurate and highly selective gas concentration data. Of course, most of these equipment are relatively expensive, with high maintenance costs, long response time, and large volume. , the operation is cumbersome and cannot reflect the on-site concentration in time, so it is not suitable for on-site gas monitoring. They are more used as laboratory gas detection instruments, and the data obtained through these analysis methods can serve as the final basis for judging the gas hazard results.
Even so, the most mature and widely used gas sensing technology still plays an increasingly important role in daily production safety, environmental protection, occupational protection, etc. After using analytical techniques to obtain the accurate concentration of toxic and harmful gases in the environment, these on-site detection technologies can be used to achieve the purpose of on-site rapid detection. Therefore, it can be said that it is these simple and reliable detection methods that can make gas concentration detection go deep into our lives and all aspects of work.
