Do you check your gas for CO?

[rob.mwpropane]

Although I just checked the cost of replacement sensors for the Analox... I may just get a Palm CO tester and save myself USD$100 per sensor change (if I can even get the Analox sensor again in two years). At USD$295 for the Analox sensor the complete USD$395 Palm tester is only USD$100 more. So the first time I replace the Palm sensor at USD$199 I'll be even and ahead USD$100 every two years after.

I jumped at the used Analox without checking availability and cost of replacement sensors... my mistake.

Edit... Oxycheq is WAY cheaper. same unit cost at USD$400 but the sensor is only USD$140 and last 3.5 years instead of Palm's 2.

Expedition CO Analyzer w/ Alarm

I'm missing something. Is there something wrong with what @Curious_George posted a link to? I'm looking to get one soon for my compressor and this is what I had planned on.

Inspector (CO) INS2-CO-01

I know there have been a few people on SB who like them.

I had missed the price. Good deal even if you have to replace the entire unit every couple of years (no serviceable battery or sensor).

Also, as far as I can tell, these are atmospheric units so you have to bag the whole unit and fill the bag from the cylinder or rig up a tube system similar to the calibration rig. The scuba centric units take readings straight from the cylinder, a little handier if your on a rolling boat checking new tanks from a shore side delivery (Cozumel cattle boats etc).

Currently I only get my tanks filled by one company and they have sensors on their compressors, so I don't test. I have debated on buying a tester but don't currently have a "need" to do so. I do own my own for EANx though.

Can’t believe that @DandyDon has not entered this conversation. Your cue maestro!

I want to think (hope) that I'll be able to 3D print an adapter to fit on it and put it up to the tank. I can't imagine it would be too difficult, but I don't know how the device works either. I'm thinking something like what comes with the Expedition. Something like this;
Gas Difuser by plexer

In reality, I'd probably never take it on a boat, it would just stay with the compressor. Would still be nice to use it on individual tanks. @rhwestfall has his tied inline, that's pretty nice.

Whatever happens, I know I'm not spending $400 on an analyser

What device are you using? I've got the Palm CO in the cart at Dive Gear Express.

I use the ANALOX EII CO detector. The sensor lasts for more than 4+ years for sure if you take care of it.

I have detected CO in one of my tanks filled by a local shop in the US. It was only 1ppm. Shop cleaned my tanks, did whatever shops do to work on compressors, and apologized profusely.

1ppm is still below the error range for CO detectors. Anything 3ppm or less is OK. The limit in the UK is 5ppm and the US is 10ppm which is way too high. Your breath as a non-smoker will show somewhere around 2ppm. A smoker I have seen it, >8ppm and as high as 17ppm.

Not in my tank. I would not dive any tank with greater than zero. The reading was consistent. When I got it, I tested all 12 of my tanks. One tank consistently scored 1ppm. The other 11 scored zero. It definitely had CO in it. You can dive 3ppm CO all day long if you like. I won't be doing that ever.

I am concerned now, he hasn't said anything here so far. Where is he? I hope that he is OK. Can somebody check on him??? This can't be.

Yes & No re CO testing.
Yes: I test every tank I pump air/Nitrox into from my compressor.
No: I do not test commercial operators air.
