I don't know, do you think there is a risk in this area separate from CO? Fill Express has published a lot about gas qualities: From Fill Express -- Quality of Breathing GasesDon
What about a methane tester???
Total Volatile Hydrocarbon Content -- Breathing hydrocarbons can interfere with oxygen intake, and short-term exposures are associated with mucus membrane irritation, nausea, vomiting, diarrhea, and confusion.
Several thousand types of organic gases and vapors can potentially be present in Air. Volatile organic contaminants can be manmade (e.g., gasoline vapor, exhaust fumes, cleaning solvents) or from natural biological activities (e.g., methane from organic decay). Because it is impractical to measure each type of organic contaminant present, they are measured as a group described as a Total Volatile Hydrocarbon Content (TVHC).
25 ppm Allowed maximum for CGA G-7.1 Grade "E"
Less than 1 ppm Test results for Fill Express gases, excluding methane

Oh, there were many waiting on the new Model 300 to come out I think. I sent an email to the address on the Support page pocket_support@kwjengineering.com advising of an approaching trip (actually my Instructor's trip) and they expedited my order. Ordering a full month in advance of one's next trip would be prudent, tho.Note: Due to recent high demand, your order may be backordered 2-3 weeks.
Look what you've done Don. Just copied that from their website.

I am not expert, but I will offer some observations - and hope others will too...Since the unfortunate death aboard the Baani Adventurer, and as my wife and I had spent a week on that boat in August last year, I have been paying a lot of interest in your threads regarding CO testers. I have found a tester in the UK with a 5 second response time and weighing only 3.5oz (100grams). It costs a little more at £135 ($270) and I have no info other than that available on their webstite and I thought that with your experience investigating this type of equipment you might like to take a look and let me have your opinion.
