Thereby ensuring that ozone generator 100 is operating properly.
It should be noted that the first conductive electrode 20 and the second conductive electrode 30 are connected to the ac voltage ± (4-5) kv. The first and second conductive electrodes 20 and 30 do not distinguish between positive and negative electrodes.
