Is it for personal safety? If so, then see Cailean Forrester's message. We use a minimum of four gas sensors: O2, LEL, H2S, and CO They are all very important at most project sites. 2. Is it for process control? Then you must determine what needs to be detected and when the response is to occur. In short, to provide advice more information is needed.
