Thnak you gemini123. I had noticed that, but I also noticed while looking at other add´s photos that the regulating knob would go from 0 up. Take a look at this add:
This one says 1.5-3 liter per minute adjustments. But I have found milliliter flow meters from laboratory supply companies in the past. So that is one option but they are not cheap.
And I could always use Hv´s recommendation of getting 3-5 bubbles per second in a glass of water, right?
That would work.
Or, better still, I could buy a paedriatic flow meter. What do you say?
It does not necessarily need to be a pediatric flow meter. Some regular medical oxygen tank flow meters will go down to very low flow rates. You would just have to make some modifications to get the flow meter in line.
I am going to buy the ozone unit that Gina found and now I want your opinion on this oxygen generator to use with it.
The price is great for an oxygen concentrator, but there are several drawbacks. First is that the oxygen concentration only goes to 90%. Generally oxygen concentrators create a higher oxygen concentration, closer to 100%.
And the flow rate will need to be reduced, so you would have to change the flow meter or use bubbling in water to get a close approximate to the required flow rate using it internally.
If the concentration only goes to 90% in what way is that detrimental to the ozone application? Would you advise me mot to buy it then?
This can still be used as long as the unit is truly a cold corona since cold corona does not generate acids. The problem is that the ozone output of these machines are based on a 100% oxygen output. As the oxygen input declines so does the ozone concentration. When using oxygen concentrators most will reach close to 100% oxygen so the difference in ozone output is minimal. The further you get away from 100% oxygen not only the less ozone that is being produced but also the more nitrogen that is present. If doing rectal insufflation this results in a lot of gas that is not readily absorbed like the ozone. So adjustments will need to be made to compensate for the ozone concentration and you may not be able to do as long as treatments due to bloating from the nitrogen.
Price wise though that it great. Most oxygen concentrators run at least a $1,000 new and the portable ones like that are in the $3,000-4000 range. So as long as the unit is cold corona I would go ahead with this concentrator and do the calculations to adjust the ozone concentration back up to where it should be.
