Cells for Mr. NotDeadYet's Analysers

[Janos]

Well I was one of the lucky receipient of Mr. NotDeadYetAndAVeryNiceBloke's analysers and having not found any at the DiveShow I'm going to get off my bottom and buy a cell for it.

Looking though NDY's posts, I'm planning on contacting these chaps - Omni Products in Coventry and buying a D-01 cell through them. I think they're around £20 + VAT but will give them a ring early next week to establish exactly how much they are.

If anyone else wants one, then I'm happy to order a cell for you. I live and work in London but it maybe possible to use the marvel that is the "YD postal system" to deliver it. I will be at various South Coast dive sites (and probably stoney at least once more) this year.

EDIT: Forgot the link - if you're at the other end of the country from me you may want to order them yourselves from here

Janos,

Thanks for the info. I don't know how I missed this post of yours when checking on "new Posts".

The price looks pretty good so I think I will be lazy, take your findings and order one direct.

Do you get Diver mag and have you read the April issue yet (my "subscribers copy" arrived last week). There is a widget in there that attaches to your O2 cell (like a plastic T piece) and directs the flow properly. Apparently, the only way to get accurate readings is to measure the O2% at one atm. The widget enables one to do this + is supposed to lengthen cell life! It is about £17.50 (+P&P?).

Let me know if you don't get Diver and I will post the info.

Janos,

Stuart's quote ref which cell we require is:-
The analysers were designed for R17Ds, exactly the same but with a jack socket (hence the cable) same as the Vandagraph.

Crikey!!! How much????

Have a look at the accessories page at www.oxycheq.com, $7 for a cheap t-piece.

All you need is some plastic pipe, just get a suitably sized t-piece for a couple of quid at most. If you want fancy then you can glue a 5/8" BSP male nipple on the end to screw into a DIN valve.

I've never used one, I just stick the cell in the flow of gas from the valve. Not very scientific but it works.

Cheers Stuart,

I'm going to order myself as I live in another part of the world from Janos. Cheers for all your help.

Any idea where to get 5/8" BSP nipples from? Buggered if I can find any.
Then again when I use my OxyGuess home made analysor it gets within 1% of the reading from a real proper one but I have modified the cell by fitting a cap to it with 2 small holes drilled in it so the pressure created by the gas flow does not affect the reading. And I have lots of welding O2 at work so can callibrate it dead easily against 100%.

Stuart,

The article states that "to get an accurate reading the measurement should be taken at one atm."

It appears that once you get a steady reading with a constant gas flow you turn the cylinder off and then wait for the reading to remeasure the trapped gas. I assume this capability is what the money is for.

I have no idea how significant the change in the measurement is + given the best estimate/not the same for everyone effects of nitrox it may not be worth the money. On the other hand, I suppose getting the most accurate reading possible is a very good thing.

Thanks Bryan,

Been a bit busy but I'll be sending off my cheque to them today...

Laters,
Janos

PS - Woz - what about Woz pipes!. Or Woz caps (for the sensors)

It's like everything, use what you are happy with.

Placcy bag and a 2nd stage works just as well though!
