do you have an analyser?

[Ian B]

I use an Oxyspy. It was fairly cheap compared to most, with the disadvantage that apparently the sensor doesn't last quite as long as some. However, its quick and easy to use.

Yeah.... cost me £4,000

Yip, got a O2II aswell, great bit of kit.

I guess I really know the answer already...so I'll be looking around at the dive show...

I won't go into the in's and out's , but the big mistake i made was.....

Leaving my twinset in a LDS and asking for a 38% mix.
Collecting the following day on shop leaving time and not checking the contents.
Doing a a dive knocking well into deco.
Diving on my computer set to 36 %.
Doing 6 hours in the pot, due to diving on AIR

Yep, me to.

It's easy to forget a mix sometimes if you've not used it for a while or if you forgot to change the sticker on it, just buy one to be safe, it's only money.

Do you have the instructions on how to make one from a multimeter

I originally got an Analox to say 'thanks for the free Nitrox' to my LDS but it has become invaluable and wouldn't go on a dive without it! Shared between myself and my bestest bud, Yipee Diver, and never rely on a shop analysis as you need to give the gas a good few hours to mix proper and to cool down before an accurate reading can be taken, as I find that the readings between shop and dive can vary!

Hi..

(no disrespect to Andy....)
I bought one when I started doing diving away from my local LDS (they always had an analyser at the sites ). I believe that if you dive with a gas, then it's your responsibility to check it before diving to make sure it is what you think it is.

I dive it, I analyse it... it may seem petty, but I like to do the actual analysis myself as opposed to watching someone else do it.

I have the OMS Analyser... good piece of kit...

Cheers

Essential bit of kit in my opinion.

If anyone is doing a homebuild, I have a couple of Inspiration cells up for grabs, one now and another couple in a month or so. A self addressed stamped Jiffy and the offer of a beer if we ever meet is all it takes.
