Device description

SP12C7 is an united gas detector measuring four (4) major gases, which result the most of the industrial accidents, to protect workers from the disasters caused by the oxygen deficiency, toxic gas poisoning and gas explosion. Measure continuously four (4)ㅡgases (O₂, CO, H₂S and Combustible Gas(CH₄)) and display their concentrations and raise an alarm when the risk occurs.
