At present, the oxygen concentration of molecular sieve pressure swing adsorption oxygen generator is the factory standard. Since there is no national standard, the factory oxygen concentration standard of industry standard and enterprise standard is 93 ± 3%. The concentration of oxygen concentrator will decrease after running for a period of events, so how much is it allowed to decrease? At present, there is no specific provision. Therefore, it is particularly important for your oxygen therapy that users know about the oxygen concentration of the gas from the oxygen generator. However, it is not ideal to absorb low concentration of oxygen for a long time.
At present, the most accurate detection of oxygen concentration is chemical test, but it is troublesome. In addition, there are instrument tests, such as oxygen meter, but ordinary families do not have it. What should we do? Let me introduce a simple test method.
As we all know, oxygen can support combustion. The higher the oxygen concentration, the more intense the combustion reaction with organic matter. We can use a toothpick with Mars to put it at the oxygen outlet of the feeder. If the toothpick burns immediately and the color of the fire is white and dazzling, the oxygen concentration is generally more than 90%; If it can burn but the color of the fire is white and yellow, the oxygen concentration is generally about 80%; If it is difficult to burn, the oxygen concentration is below 70%, and the adsorption tower should be replaced.
