It is consisted of the gas-***ecting main machine and the gas ***ector and it is used to ***ect the density of the flammable gas, oxygen, or poisonous gas in the working environment.
This system adopts 32 digit embedded micro processor as control unit, high-performing catalytic air-sensitive element or high-precision imported electrochemical sensor as ***ector which has high sensitivity and quick response. When the ***ected gas density in the air reaches or exceeds the preset value, the controller will give out audio-visual alarm immediately to remind you take safety precautions and start exhaust, control and start exhaust or other peripheral devices to avoid explosion, fire, toxicosis to protect the safety of life and treasures.
This system applies to metallurgy, petrol, petrifaction, chemistry, light industry, coking, municipal administration, gas, pharmaceutical, sewage dealing and many other special industry and field that need proofing for fire, explosion, and toxic gas leakage.
