When it comes to gas detector, often refers to portable gas detector, which gas detector can be divided into a single gas detector, multi-in-one gas detector, that is, for a gas detector and for a variety of gas detection at the same time, there is generally a choice of built-in pump, position pump pump suction type detection principle or natural diffusion detection principle.Multi-in-one gas detector can be made into two in one, three in one, four in one gas detector.Today I want to share with you that four in one gas detector can detect which kinds of gas knowledge, let's take a look at the following.
Four in one gas detector can detect the following gases:
Combustible gas (LEL) :There's a lot of flammable gas,Such as hydrogen (H2), carbon monoxide (CO), methane (CH4), ethane (C2H6), propane (C3H8), butane (C4H10), ethylene (C2H4), propylene (C3H6), butene (C4H8), acetylene (C2H2), propionate (C3H4), butyne (C4H6), hydrogen sulfide (H2S), phosphine (H2S), etc.PH3), etc.
Oxygen (O2) : Oxygen is extracted from the liquefaction process of air, and the oxygen content of air is 21%.It is the basis of all breathing and burning processes and is therefore a prerequisite for almost all living processes.
Carbon monoxide (CO) : A carbon and oxygen compound, chemical formula CO, molecular weight 28.0101, normally a colorless, odorless, tasteless gas.
Hydrogen sulfide (H2S) : H2S is an inorganic compound with the molecular formula of H2S and the molecular weight of 34.076. It is a flammable acidic gas under standard conditions, colorless, with the odor of rotten eggs at low concentrations and sulfur at very low concentrations. It is highly toxic (LC50=444ppm)
Four in one gas detector mainly detects the above mentioned several gases, about the four in one gas detector content will share here first today, gas detector can be generally applied to closed and semi-closed space, and the fire scene after the safety inspection.Application in many fields, such as petroleum, chemical industry, metallurgy, mining, fire protection, gas, environmental protection, electricity, communications, paper making, printing and dyeing, grain reserves, urban water supply, sewage treatment, food, scientific research, education, national defense and other fields have been applied.
