4-20mA H2S Hydrogen Sulfide Gas Transmitter
 4-20mA H2S Hydrogen Sulfide Gas TransmitterTGas-1031 SeriesCombustible, Toxic and Harmful Gas Sensor Analyzer cancontinuously measure the concentration of site gas, and convert theconcentration signal into 4-20mA output. It is extensively appliedin petroleum, petrochemistry, chemical industry, gas, coal,metallurgy and electric power; safety detection in municipaladministration, telecommunication and traffic tunnel construction;the place where combustible, poisonous and harmful gas might leak,such as gasholder station and special industrial factorybuilding. Main features4-20mA H2S Hydrogen Sulfide GasTransmitter
