Independent Combustible Gas Detector
Gas detection alarm control panel
The gas alarm controller is used to observe, control and maintain the gas detector from a distance. Any operation inside a controller has to be performed by a professional. All operations must comply with local regulations and site procedures. The controller is wall-mounted controller, which can be installed directly on the wall of instrument room, duty room or workshop. The channel input of the controller is standard (4 ~ 20) mA signal, corresponding to the corresponding range, LCD screen displays the concentration of the gas channel and alarm information. *There are 2 channels, 4 channels and 8 channels for optional. One channel can equip one gas detector to show the corresponding measured value of gas concentration. The instrument can be widely used in petrochemical, artificial gas, metallurgy, iron and steel, coking, electric power and other combustible gas in various industries. It is the ideal controller to ensure property and personal safety.
