The ozone levels are completely adjustable and controllable by simple adjustment of the following two controls (different than the EXT50 Ozone Generator):

1. The Oxygen Flow Rate: This is the speed at which the oxygen enters the ozone generator. Increase the flow rate and the oxygen spends less time in the ozone generator, therefore producing less ozone. Slow down the flow rate, and the oxygen spends more time in the ozone generator, therefore producing more ozone.

2. The dial on the Ozone Generator: This dial from 1 through 10 on the ozone generator, speeds up and slows down the speed at which the electrical field flashes on and off, around the double walled glass tube. Increase the frequency of the flashing (by turning the dial up from 1 towards 10) and you increase the amount of ozone that is produced. Decrease the frequency(by turning the dial down towards 1), and you decrease the amount of ozone that is produced. By using this dial on the ozone generator, you may choose between 10 different ozone concentrations at each oxygen flow rate. This provides you with precision contro, outstanding safetyl, and 50 ozone concentrations from which to choose!
