I was filling up a bag with my O2 detector in it and has I was filling it up the O2 levels were dropping and it dropped to around 15 percent before I let O2 in because I was doing it at night and the detector was beeping super loud so I didn't wanna wake anybody.
My question before I try to fully fill the bag on a day where nobody is home or when its pretty noisy and test out the mixture levels of my party helium tank that says 100 percent helium on the tank. The O2 levels going below 20% is a good sign right? anything under 20 percent O2 you CTB right? Obviously Im hoping that the party tank company didnt lie on their tank and it is pretty close is 100% helium, but if its still under 20% lets just say hypothetically 90/10 mixture or something CTB is still possible right?
