Oxygen Meter Portable Oxygen(O2) Concentration Detector

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 instrument is a natural diffusion method for detecting gas concentration, using high performance electrochemical sensor, with excellent sensitivity and excellent repeatability.The instrument adopts embedded micro control technology, simple operation, complete functions, high reliability.   
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.
