How to know that the oxygen generator is oxygen?
Currently, the oxygen concentration standard of the molecular sieve pressure swing adsorption oxygen generator is the factory standard, because there is no national standard , The factory oxygen concentration standard of industry standard and enterprise standard is 93+3%. The concentration of the oxygen generator will drop after a period of operation, so how much is allowed? There are no specific regulations yet. From this, the user knows about the oxygen concentration of the gas from the oxygen generator, which is very important for your oxygen therapy. The long-term absorption of low-concentration oxygen cannot achieve the desired effect on oxygen therapy. (At present, some people say that 30% or 60% of oxygen is healthy oxygen, and people can’t breathe high-concentration oxygen, which is a stealing concept.
Currently, the most accurate detection of oxygen concentration is chemical testing. But it is more troublesome, and there are other instrument tests, such as oxygen meters, but ordinary families do not have them. What should I do? I will introduce a simple test method below.
As we all know, oxygen can support combustion. The higher the concentration, the more intense the combustion reaction with organic matter. We can use a toothpick with sparks and put it into the oxygen outlet of the oxygen supply. If the toothpick burns immediately and the color of the fire is white and dazzling, the oxygen concentration is generally 90 % or more, if it can burn but the color of the fire is white and yellow, the oxygen concentration is generally around 80%. If it is difficult to burn, the oxygen concentration at this time is already below 70%, and the adsorption tower needs to be replaced. Why choose toothpicks Instead of using cigarettes or chopsticks? Because 70% oxygen can also make cigarettes burn very vigorously, while toothpicks are difficult to catch fire.
