This is a Carbon Monoxide tester

[scuba70]

My LDS actually has an inline version of this in their fill station. It will also change color if any CO is detected. I know that they also have their air tested quarterly because they have the framed certificate next to the fill station. It's kind of a nice safety feature.

A lot of places use these guys for scheduled analysis. They supply you with a vacuum cylinder, you take your sample, close the cylinder and they send you back a report with everthing that is in your air and whether it passes the requirements for that grade of air. I just noticed at their website that they are also the supplier of the detector that Don mentions in his first post.

I bought that exact same unit from Scuba Toys last year and i bought 5 extra elements .I was told the elements are available from hospital supply places I don't know if that is true or not.I am sure it was a lot less than $90.00 from them.

It was funny when I bought it Joe asked why I wanted one and I told him about the coco view incident which had just been told to me "first party" by someone who was there .

I read in their website that it is good for up to 10 tests. I imagine it is a cumulative thing, the more co it is exposed to, the darker it gets? Or perhaps it reacts to some reactive component of dryair and loses its effectiveness?

So, $6 for 5 test, it is about 1 buck a test. If it is for 10 test, then it is about 60 cents a test. If you dove 5 days, and tested a tank each day, then it would add only $6 for the week of diving. Not a bad deal, considering how much one spend on a dive vacation, or simply on a tank of Nitrox.

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.

Thanks, knew you used one from the Maldives death thread.

What levels of CO correspond to the colours in the diagram?
Maybe all PADI operators should be required to have one of these ?

Most of the ones outside of the US are not following existing testing rules now, but - explain your idea...?

Sure, as all should, but you're in NC where they have to answer to the USCG, USDOT, and US Court System. How often are these mentioned or requested outside of the US?

Florida has its own laws and regulations in addition to federal. Do you have a passport?

Yeah, and the resort is going to release the results of their study someday. :dunce:

I guess my sarcasm wasn't obvious in post #1 and what I wanted to encourage was feelings of forcing Operators outside of the US to comply with the Padi rules and put their test results on their web sites if they want our tourist dive business. Doesn't seem to be working.

We shouldn't have to test our tanks. The Ops should.

Well, maybe it would help to review symptoms, toxidity, etc...?

I'm hoping this thread will worm it's way back to ALL air stations and light a fire.

Is bad air a problem?

It depends upon who you speak with and what population of compressors one examines. In Canada and the USA fire halls generally have better air quality these days than commercial dive operations, by a considerable margin. One can determine this by examining the pooled sample results submitted to the compressed breathing air laboratories which will show the failure rate frequencies for each contaminant such as CO, CO2, volatile hydrocarbons, etc.

For example, it is written in the DAN article below (and from a similar article 5 years previously in the same magazine) that of all samples submitted to the two laboratories listed in the article that about 3 percent of samples fail for carbon monoxide at the 10 ppm level. That is a very high failure rate, but also similar to the CO failure rate from the US Navy (2.5 percent if I recall correctly) for their compressed air samples from over a 5 year period.

There is a sporadic problem of CO contamination in compressed breathing air particularly when compressors are poorly installed and likely to over heat which leads to burning (pyrolysis) of the oil used to lubricate the compressor. Based on geography and average ambient temperature one is more likely to find overheated compressors in the tropics where much recreational diving is done. A less common source of potential CO breathing air contamination than from pyrolysis of the compressor oil, would be carbon monoxide which has been entrained into the compressor from an external source such as exhaust from the engine used to drive the compressor, or the boat or generator exhaust

I have the CO Cop which is the same thing. I use it on out of the USA dives or when I have reason to suspect I may not be getting quality air (the guy comes in from the air fill area smoking a cig...)
