Hello all,
New to the forum, so I’m sorry if I posted thread in wrong section.
Just built a new “
Michael McFadyen” style Nitrox Stick and I’m having a bit of a mind boggle with its operation.
Also bought two new NRC Analysers (I know they’re cheap, but work). I’ve testested them both with ambient air and pre-filled 32% Nitrox tanks, both read 21% with ambient air and 32% off the air in tanks.
Here’s the query:
- Turn On compressor with bung in analyser port and fills tanks correctly. Then (without oxygen ON, or even connected to stick), take out bung, insert analyser, and get 21% oxygen reading...everything good at this point.
Then without even plugging in oxygen line the analysers will both read 21% oxygen for about 20 seconds then start climbing 1% oxygen about every two seconds until the max out...at about 97-98%...
How is the oxygen rising in the mixing stick to the output without an oxygen supply?!?!
It’s built to specs, two new NRC Analysers, and still this issue persists.
Any assistance much appreciated!
Thanks mates!
