The Best Gas Detector to Use
The gas detector is a measuring instrument used to detect the concentration of gas leakage, mainly using gas sensors to detect the composition and content of gas in the environment. For all kinds of different production occasions and testing requirements, choosing a suitable gas detector is something that every person engaged in safety and testing must pay great attention to.
Confirm the gas type and concentration range to be detected: the gas types encountered by each production department are different. When choosing a gas detector, all possible situations must be considered. If there are a lot of methane and other less toxic alkanes, it is undoubtedly the most appropriate to choose an LEL detector. This is not only because the principle of the LEL detector is simple and widely used, but it also has the characteristics of convenient maintenance and calibration.
If there are toxic gases such as carbon monoxide and hydrogen sulfide, it is necessary to choose a specific gas detector first to ensure the safety of workers. If there are more organic toxic and harmful gases, considering the low concentration that may cause personnel poisoning, such as aromatic hydrocarbons, halogenated hydrocarbons, ammonia (amines), ethers, alcohols, fats, etc., you should choose the light gas introduced in the previous chapter. Ionization detectors, and never with LEL detectors, as this could result in personal injury or death. If the gas types cover the above types of gases, choosing a composite gas detector may achieve twice the result with half the effort.
