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 :-(
