The single-gas detector  can continuously monitor gad density. It is applied for explosion-proof, toxic gas leak detection, rescue, and also applied in the surroundings such as underground pipe and mine, to keep the workers safe from invasion of the toxic, deleterious gas and avoid damage to equipment. The detector inspects oxygen density by natural diffusion and adopts imported electrochemical sensor(catalytic combustion sensor for flammable gas), having good sensibility and excellent repeatability. The device has embedded micro control technique and Chinese user menu, making the operation easy. Complete function and dependability makes the whole device a leader in the nation. The cover of the detector is refined from high-intensive engineering material (compound elastic rubber), which made the detector touches well, waterproof and explosion-protection. Application: The detector monitors the oxygen density and is widely used in metallurgy, electric factory, chemical, mines, tunnels, underground pipes etc, effectively prevent toxic accident.
