The portable oxygen detector is a kind of essential safety instrument which can continuously detect the oxygen concentration in the working environment.It is suitable for explosion-proof, toxic gas leakage, underground pipelines or underground mines and other places, can effectively ensure the safety of the staff's life is not infringed, the production equipment is not lost. This O2 detector is applicable to the concentration of oxygen in the ambient air detection, are widely used in metallurgy, power plant, chemical, mine, tunnel,underground pipelines and other places, effective prevention of hypoxia and oxygen poisoning.
OT131 gas detector is a pump-suction ultra-high sensitivity gas detector. Electrochemistry sensor is more suitable for locating and detecting leakage gas. It is compact, easy to operate, easy to carry, and can also be attached with a flexible probe, comfortable handle. It also can show a unique concentration curve.
