All about Oxygen O2 Analyzers, including DIY

[joens]

when I got nitrox before I had my analyzer I would check it myself with the one the shop had . two weeks ago I had 2 tanks filled and I didnt verify the mix as I was getting my analyzer kit and wanted to check up on the LDS. as the 2 tanks came from the shop they were labeled as 36 and 40 [what I had asked for]
when I checked them with my analyzer the 36 was 35 and
the 40 was 36. next project fill whip.

Ha! You didn't turn them upside down, roll them across the floor and tap twice with a plastic screwdriver handle. That would have unstratified the stratification that occurs during storage :doctor:

I don't want to hijack this thread, but after the 'stratification' thread, I've talked to a few chemists who thought I was nuts for even thinking it could happen.

Some dive shops are great, some are...less great. In any event, it's nice to be able to test fills in the field - sooner or later the need arises and you'll be able to respond appropriately the first time someone says, "I think that one is 36%..."

It's also a geek thing - build your own little toy to befuddle the world with!



My el Cheapo II has an external sensor.

I can understand the joys of DIY. Note to Padipro- don't just show us the pictures. We need a complete list of what, where and how for the light.

get the 'Divelight Companion', it's FULL of useful info on building your own light. I did a NiMh that is still going strong!

Justed wanted to second (or third) the comments about the El Cheapo II and Patrick Duffy. I have built two in last two weeks. The first I acquired all the parts myself and bought just the sensor from Patrick. When I ran into problems I contacted Patrick and he walked me through the problems and got me up and running -- This was above and beyond given that I did not buy the parts from him. The second time I bought the kit -- the only way to go from now on. I have compared the readings against an OMS at my local LDS as well as one other commercial analyzer and they were identical. The toughest part to the whole process is designing and cutting the case and this is not very difficult. I highly recommend the El Cheapo II.

What do these kits come with. Any soldering involved? Do the have PCB w/everything soldered on them? Is this something you could get the schematics for & buy the parts @ say... Radio Shack?
