To be honest I have never tested it. Dident want to fork out the big cash for a quality meter.
I've thought about doing this before but couldn't ever get my hands on a couple of decent priced concentrators, I would love to see some pics of this in action. I've since converted to organic dirt so I won't be using this anytime soon but I've been thinking of running a DWC system with an O2 concentrator in the rez...very cool
I used to work for a company who made Concentrators... spare parts came home....lol... as far as pics "in use" the system is mounted in the basement and I have hoses run through the walls to hose barbs in the room.. just use it as your air to power your stones.

As far as C02... I built a Natural gas burner plate w/ reg and run Cool Tubes and thermo control so heat is not an issue.
