Recommendations for O2 and CO analyzers

[Hojo in SC]

Can somebody explain the process for testing a tank with the Oxycheq? Do you need a flow restrictor, or do you just barely crack the valve on the tank and use the nozzle they show in the picture on their site? How long do you have to test to get a reading? etc...

Yes, I would like to know too, I think I read some are putting a good plastic bag with the monitor in it, over the tank and purging the tank into the bag, close and then take the reading.

Warning! If you do, crack the valve first, then place the bag. I send a bag and unit overboard once the other way.
