Specification :

Fixed gas sensor can be detect combustible gas, such as: CH4, C4H10, H2S - hydrogen sulfide, Cl2 – chlorine, CO - carbon monoxide, HCN - hydrogen cyanide, O2 – oxygen, NO2 - nitrogen dioxide, LEL combustibles, NH3 – ammonia, SO2 - sulfur dioxide, ect. You can choose one type of gas to detect according your installed place.

Features
