Good question. I just looked at the manual that came with it (which is essentially some pages stapled together). The front of the unit has a knob that allows you to adjust the ozone with 10 increments. But the manual does not give a calbibrated ozone output chart. They do have a chart that shows how the air flow rate effects the concentration. But it would be similar to the Synergy in this regard.
Now, I always just used it on full throttle for rectal insufflation. I would guess that ear insufflation would be where you'd want the ability to turn it down to a lower level.
