Analox O2 EII ???

[mrtechbench]

I have been very happy with my o2eii and because they did a great job with the O2 tester I searched for that analox co tester when I was finally interested in buying one. I couldn't find it and ended up getting palm co.

Have used an O2eii for ten years. I like its simplicity. I also have a trimix analyser so it is good to have a separate analyser for validation.

I have purchased the last three replacement sensors for the O2eii from Vandergraph (link in post #3) for around £60/$70 and they work well.

Similar to Wibble, I've had my analyser for 10+ years and just update the sensors from Vandagraph at intervals of 2-3 years. Use my trimix analyser as a comparator these days, but stick to the Analox for nitrox trips because it's easy to use and small in the case.

What joy, my trimix analyser’s not right — the helium sensor is reading wrongly — 27% when the gas is 46% and 65% when it’s 87%.

Now to source a replacement He cell, or find another analyser :-(

Been using O2 EII for several years. on my 4th or 5th sensor. Overall quite satisfied. My source of sensors is OxyCheq. I use a sensor plug to manage sensor life, and change the battery before every trip. The only downside is the calibration knob is too sensitive, and too easy to accidently move out of adjustment.
I've found discrepancies on 3 trips where my O2E doesn't match the LOB Nuvair, and my meter was the more accurate - 4% discrepancy. Once time my meter read lower than the LDS but changing to my spare sensor resolved the issue, and the LDS and my meters matched.
For now, I'll keep using the O2E.

Is there an equivalent sensor from OxyCheq for the R-33DE sensor? I don't see the exact sensor that's called for in the Analox O2 EII documentation.

The Analox number is 9100-9220-9B. That crosses over to the AST-40D. But I've never used that sensor. Maybe others on here have and can offer their review.

Does anyone know the size of the o-ring for either the insert, or the cap for the original OEII?
