Ion counts show you
"How far negative ions travel".
You cannot evaluate performance of negative ion generators without negative ion count information.
It is possible that some million negative ion molecules are detected at the blow off point
but very few can be detected at 50/100/200cm away.
If only less than 2,000-3,000 (pcs/cc at 1m) negative ions can be detected,
the performance of the ion generator is not good and it is only good for mobile or other special use.
Not only ion counts in the blow off direction but also those in angled directions (found on the next page) are an important factor.
