Ray H I dive with nitrox, din and yoke tanks, does the DIN adaptor and yoke fitting need to be O2 cleaned to just measure tank pressure?
STEVEN C I have never seen one o2 cleaned although if concerned by two and use one strictly for nitrox testing.
MICHAEL G yes it dose work's good.
Dan M Can't tell you for certain but I don't think so. I use the same tank pressure checker for my din tanks and regs. I dive nitrox, too. Like most modern gear, it is probably fine up to 40% O2 but beyone that, my guess would be that it would need to be O2 clean.
STEPHEN B No not at all. The one I got was clean and free of all oils and works great.
DARRYL R No, it does not need to be O2 cleaned up to 40%. anymore than your regulator would need to be cleaned
ARTHUR C No. Pressure is pressure.
