The key indicators of ion fan quality?
Key indicators for measuring ion fans:
1) Ion balance: The number of positive and negative ions produced by the ion fan is the same* best, that is, the smaller the ion balance, the better
2) Discharge time: the time to eliminate static electricity, the faster the better
3) Ozone concentration: high-voltage corona discharge will produce ozone, which is harmful to the human body. A poor ion fan can smell obvious peculiar smell, and the ozone produced by a good ion fan is lower than the concentration of the atmosphere itself.
How to detect ion fan?
The electrostatic field tester (supporting electrode plate and high-voltage generator) or desktop charging plate monitor (CPM) can be used to detect the ion balance and discharge time of the ion fan
