Introduction:
The Precis-Ion™ Air Ion Counter Model AIC3Pro
is a true ion density meter, based on the Gerdien
Tube condenser. During operation, a fan draws air
(and the ions in that air) in through the top intake
grill. The AIC3Pro counts and displays the number
of air ions and the air exits from the bottom outlet.
Do not block the air
intake. This will affect
meter function!
Do not use plastics,
adhesives, labels or
stickers above this
point. These Insulating
materials may hold a
static electric charge
and repel ions,
especially at higher
ion concentrations.
Do not block the air
outlet. This will affect
meter function!
