Online Explosion-proof Gas Transmitter
TGas-1031 Series Combustible, Toxic and Harmful Gas Transmitter
Brief introduction
TGas-1031 Series Combustible, Toxic and Harmful Gas Transmitter can continuously measure the concentration of site gas, and convert the concentration signal into 4-20mA output. It is extensively applied in petroleum, petrochemistry, chemical industry, gas, coal, metallurgy and electric power; safety detection in municipal administration, telecommunication and traffic tunnel construction; the place where combustible, poisonous and harmful gas might leak, such as gasholder station and special industrial factory building, etc.
