Hello:
Does anybody have an idea how a corona discharge type ozone generator that is preset to 300mg/hr could be modified so to reduce the output?
Do you have a circuit diagram of it?. All you need to do is reduce the voltage it generates, but that depends on how it works.
Failing that, you could simply use 'burst fire' power control - turn it on for 10 seconds, then off for 10 seconds = 150mg/hr. Adjust the on/off ratio for your required output.
