Analox O2Ell Fault or O2 Sensor?

[Graeme Fraser]

Hi All

My Analox O2Ell appears to have stopped working and not sure if it's just the o2 sensor or the unit itself. Usually when I've had sensors expire, they've gradually started giving inaccurate readings. However this one is only about 10 month's old, with low to moderate use.

Yesterday it was working perfectly but today will only read between 0.01 to 0.03 when I turn the calibration knob. Apart from that, nothing, even if I unplug and replug the sensor and battery. I also tried it on a range of mix's up to 100%.

I'm a bit reluctant to splash £100+ for a new sensor if it's actually the device that's faulty, so would welcome any input from anyone who knows what the problem is likely to be.

Many thanks. G

Did you check the batteries? The issue maybe with the batteries.

You could check the output of the sensor with a multimeter. Not sure what the reading should be but I am sure that someone on the rebreather forum could tell you.

Yes, changed the 9v battery, but no luck. Thanks anyway.

Worth a shot. I'll ask one of my more electronically minded mate's for a hand. Thanks.

That is way too much, I think that I priced it a while back for around half this figure. I'll try to find the site for you and post it here.

Here, choose the appropriate version:

Most likely this one:

R-33DE Oxygen Sensor (0110224)

Compatible with: Analox O2 EII, version with JST connector Replacement of the Analox O2 EII Oxygen Sensor 9100-9220-9B

www.vandagraph.com

or this one:

R-22DEM Diving Oxygen Sensor (0110225)

Compatible with: Analox O2 EII, version with 2-pin Molex Connector. This sensor is for the original design O2 EII. Most O2 EII analysers require the R-33DE Oxygen Sensor (0110224). If you are unsure which sensor you require, please call or email us. Replacement of the Analox O2 EII Oxygen Sensor

Thanks @BoltSnap that's a lot easier to swallow. I'm going to switch out a mate's sensor today, just to make sure it's not the device, then go ahead with the one from Vandagraph.

Will be waiting to read your results. Very curious about the cause of the issue. Good luck to you.
