this will probably be my last inquiry before I ctb with scuba. Do you any of you know how to test nitrogen purity in simple terms? I read some use a gas flow restrictor but is that the same as a regulator? I bought an oxygen detector that was recommended just waiting on it to deliver and have a 40 cuft cylinder though am a tad afraid of using too much for testing.
