DI is not 10 Mohm?  Am I wrong?  What is in there?

Enough to drop the 10 mega ohm water to 500 ohms??

Richard,
Its needs a catalyst to form FAST, but even without it some is there, just
not much.

Yes, but it needs a catalyst. So there would not be any during a quick probe
measurement, at least not enough to affect the readings significantly.

Carbon dioxide dissolving in the water CO2 + H2O -> H2CO3

Paul, care to expand on that? Where would carbonic acid come from?

Sounds like you were getting a little carbonic acid with the water
collecting in the probe...

We used a conductivity probe and meter.

Ok guys... remember your chem. & physics....

It doesn't matter what you put in the air stream as particulates, remember
these
are particulates not moisture vapor...The individual particles will charge
in a
moving air stream when there are different potential voltages around because
the
surface of the particular charges...

Thunderstorms... updrafts sweep chargeable mass to collection areas prior to
discharge via lightning...

Also if I remember correctly ~300v/m atmospheric potential in a free open
environment...

And Mike... how did you measure that...

If you don't remove the minerals from the water, then the nozzle
apertures will eventually clog.

Steve:
It ain't clear that the DI is doing it, but it does make sense, since
the DI is SO much less conductive, lacking any ions in it, that it could
hold a charge a lot better than tap water.
Maybe you want to consider using soft water, to eliminate the chlorides,
but retain the ionic strength?

This may be an off the wall question but here goes.



We have some misting fans that we use for humidification that we've just
recently put in a deionized water source for.



Now it seems that there's a static charge being generated at the fans
that
I've never noticed before. Could it be possible that we're generating a
charge at the fans because of the DI water?
