Testing for Carbon Monoxide May Save You

[DandyDon]

Unless you are using a defective analyzer. You should be using two different brand analyzers.

CO testers are easy to test, to at least see that they work. Breathe into it, or better - get a smoker to blow. It should react with either tho. How accurate they are depends on calibration, but then even if not - it should still react to dangerous levels.

Why use different brands?

.... Two of the tanks jumped up to 25ppm and started flashing a TOO HIGH! ...

Hope other divers read your post and it scares them to start asking questions about CO.

Like you, I test every tank.

Unfortunately serious. I now only do my own fills or use a "trusted" source. Haven't adopted analyzing every tank yet.

"Trusted" sources have almost killed a diver less than a year ago 50km away from where I live.

If one brand/model has a hardware/software issue, you want a different brand to make sure that you aren't getting false readings from both units because of hardware/software issues that will effect all units from the same manufacturer with the hardware/software issues.

Then which one do you believe ?

Whichever one is closest to your third model.

If any of them says there is high level of CO in the tank, just don't use that tank. So, the one that reports the highest CO level. ...


For me it feels that one analyser is better than none. ...

When the compressor station has an inline CO detector, I still use a handheld one to make sure that there are no issues with either analyzer.

Sure. It's probably not the owner running the fill station, but some employee who wants to get his work done quickly - so some ignore warnings.

I guess you were joking, but we actually heard from a couple who survived the infamous Maldives CO tragedy years back. As sick as they got, and even witnesses death from the toxic tanks, he still was diving without a CO tester. His wife quit diving with him tho, last I heard.

More information on this incident, please.
