How to prove it is oxygen?

Time:2017-1-3    Read:103

We have special after-sales service staff that can use oxygen meter to detect the oxygen concentration produced by oxygenator. Oxygen combustion can also be used to detect the oxygen by aid of a lighted cigarette, however, this detection method is not recommended because it is inaccurate and a little dangerous.
