This is a Carbon Monoxide tester

[DandyDon]

For the record: PADI requires all registered Operators to have quarterly fill air tests with an accredited lab - there are several labs that serve the need worldwide - and keep records available, but there seems to be no enforcement unless a complaint is filed and if you ask to see the records before booking or on arrival, it seems unlikely there will be any.

How Important Is Trusting The Air Supply...?

This is a Carbon Monoxide tester: $90 US plus shipping

It will last for 5-20 tests, unless you get a positive hit: $6.66

They will ship worldwide...

CO-Cop, Carbon Monoxide Detector - Air / Gas Analysis

How about we pass the word to All Operators worldwide that they must have one of those available and let us watch a test of a randomly selected tank everyday, and that we are willing to pay 10c per tank more or whatever the real cost would be - or we're not going...?!

I guess if I want one, I have to buy my own, huh...?

They generally don't care and getting them to start caring would require industry wide pressure. The general reply I get is "We've had no problems." I've had no house fires since I moved; should I ditch my smoke detectors...?


Some here will argue that quarterly air tests mean little. It's a Padi rule, not mine - so what do we think of Ops who ignore safety rules? And what about maintenance records open to the customers?

Why do we shop more based on price, comfort, food but so very few even ask to see compressors themselves, to see maintenance records and air tests, etc? True, deaths from bad air are fairly rare - but they happen, and those are all from Operator negligence.

Do you think that this tester is reliable?

Do you think that this tester is reliable?

Well, I think it is more reliable than not testing. You could ask the company how reliable...?

My search settings are geared for US searches. You may well have such labs in Europe, too.

I never hear of this tester in Europe. It is a good idea and I will ask my dive shop.

Maldives is a destination very popular for Europeans divers, less for Americans because of the long distance. I never thought that in Maldives, the air could be bad. I am suprised.

Ok, so it is good for 5-20 tests, are there any indications that it is a dead test plug? IE color change? Do you have one of these? I don't remember you using one in Coz, but I wasn't paying attention and it was only one day...

5-20 seems like quite a big range?

I like your view and the responses are well?
"We've had no problems."

Nah I don't carry one. My real views are in the last two paragraphs of post #1.

BTW, I did ask Del Mar Aquatics about their air test records before going. They have their own compressor but have never ran a test that anyone remembered.

But if I was traveling over seas to dive, I probly would own one.

The 5-20 range is because the filter life is dependent upon the quality of the air you are testing. Better quality air, the longer the life of the filter.

What levels of CO correspond to the colours in the diagram?

Maybe all PADI operators should be required to have one of these ?
