Nitrox mix changes overnight?

[all4scuba05]

Read on another thread that someone analyzed their mix upon pickup. (27%)
Next day he verified the mix with his friend's analyzer before the dive. Got 23%.
Any thoughts?

Human error in reading percentages in the first place. Aussies.

Bad sensor??

Partial pressure blending? Mix not completely blended when first analyzed?

 

[truck1]

analyzer not held close enough to the valve,not not calibrated properly or removing the analyizer before its finished.

Aussies.

No one would call for an Aussie. Especially the PADI trained Aussies.




Just so you all know, that's said completely in jest. Some of my best friends and best musicians I know are from Australia. They have a very cool sounding accent, are some of the nicest people on earth, and their only real downside is that they live so far away from the US that the plane ticket is outrageously expensive. I would gladly call on an Aussie for anything, just not on the phone becuase that'd be one heck of a phone bill!

that does sound like an error in the analysis

Take it back 23% is hardly nitrox. Just my opinion.

Off the wall, if a steel tank could have been rust sucking up some O2
