I got nitrox certified about 5 years ago and imediately went out and bought an O2 tester. well I have never used it, because when I get Nitrox at a shop I use their tester.
I assume that it is now trash or at the very least needs a new sensor. since I have never used it, I guess it will just sit in the box forever.
what would you do with it? not thinking ebay is very nice without a large bold warning. Am I wrong about the sensor?
