PROBLEM TO BE SOLVED: To provide an ozone generator monitoring method and an ozone generator monitoring system capable of calculating proper ozone concentration with time, and conducting proper notification at timing that maintenance or the like should be conducted.SOLUTION: There is provided an ozone generator monitoring method having an acquisition step for acquiring electrification time needed for generating ozone by an ozone generator and a current value thereof (Step 2), calculation steps for calculating ozone concentration of ozone generated by the ozone generator based on acquired current value (Step 3 to 6), a determination step for determining whether maintenance of the ozone generator is needed or not based on calculated ozone concentration and electrification time (Step 7), and a notification step for notifying that maintenance should be conducted when the maintenance of the ozone generator is needed as a result of determination in the determination step.SELECTED DRAWING: Figure 5
