At some point you have to trust someone.A lot going on here.
I'm just a diver who wants clean air. I'm a simple guy. Thanks to you guys, I
No longer trust my dive shop, the next dive op I'm going to dive with, or for that matter...I don't trust you guys either. It is as it should be, alas.
I am forlorn and lost in a world of distrust. Nonetheless, I will press on. Ive now learned that I must check my own air for CO and O2 content. I'd like to test it for polyolefin, methacrylate degradation byproducts and phenols but don't know if that's gonna happen. I don't even know what those are...but don't tell me, cuz I ain't gonna trust you anyway.
So, what do you guys use to test your air? I have a nitrox measuring device but that's it. (you can answer my question but I'll still "trust but verify" you dirty lying sumbitches.
I decided to trust the manufacturers of my CO test equipment. Formerly analox, now divenav. I did confirm that the divenav cootwo and the analox CO tester gave the same results on good and contaminated tanks.
So to answer. In my opinion. Get a cootwo, and when you test oxygen levels you also test carbon monoxide with no extra effort. Or get a seperate CO tester.
I, too, wish I could truly analyze my gas for all contents. I mean who knows if the tank monkey at my LDS farted into the compressor's intake?!? Unfortunately it's too expensive and time consuming so I have to live with analyzing only O2 and CO levels.
