La description

carbon monoxide(CO) detector is a portable detector with intrinsic safety, which continuously monitors carbon monoxide(CO) concentration. 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 carbon monoxide(CO) concentration 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.The cover is refined from high-intensive engineering material,the detector touches well, waterproof and explosion-protection.
