O2 Analyser or just check on the boat..?

[GLOC]

I started this thread in the 'I learned about diving from that' sub forum and it is worth looking through as to why you should analyse your gas before every dive.

2 Examples of Why You Should Always Anaylse Your Gas

Some of the examples in there are quite scary. I know what you are saying Rob, but I would rather check than assume.

I hope 201 goes OK


Way to relaxed an attitude for me. I always check my mix even/especialy when i ask for air.


If you regularly dive nitrox then Id recomend geting your own analisor.


Analisers on livaboards have a hard life.

Out of interest? is the 02 cell in the bit you stick on the tank?

If so how do you regulate the flow to stop the presure of the gas giving a false reading?

No idea Mark. I haven't got one yet, but will be ordering one at the end of the month when i get paid. I'm waiting on an email from them, but am pretty sure it comes with a restrictor that isn't shown. As soon as it arrives my "oh, it's fantastic Crapalox O2EII" will be confined to the bin. Not that it works anyway. It's the fourth one i've had.

Dive Budda has one, so he may be able to give you a better answer...

Should analyse your gas on liveaboards even when you've ordered air.

Once in the Red Sea my O2 cylinder on the RB was filled with 90% Heliox.

I've also stopped someone in the UK from using the 12l of 18/50 trimix I was decanting from as a single cylinder. (He was just about to attach his reg to it when I stopped him).

Just checked the conrad site - they supply a T piece of plastic which analyser sits in the middle of, it looks like you flow gas through the tube and the analyser picks up the mix.

If you check out their site as well, there's a £3 off voucher when you first logon, bringing the delivery down to £2.99 instead of £5.99.

My £££ situation is low for a month or so now so I may have to borrow on this occasion.

Based on your thoughts - analysing is the way to go.

Thanks for your input.
