Precis-Ion™ Air Ion Counter Model AIC3Pro is a lightweight, handheld Gerdien condenser meter that measures the number of positive or negative air ions. The meter can display both polarities and their sum. It also features a Li battery and data/time stamped data recording via a removable MicroSD card.

The Precis-Ion™ AIC3Pro Air Ion Counter
measures ions over a wide range without
sacrificing precision by providing two operational
scales:
• 10 to 2 million ions per cubic centimeter (for
measuring low-level and ambient conditions)
• 20,000 to 200 million ions per cubic centimeter
(for measuring air ion generators)
Dual-Read Mode with SUM:
• displays both positive and negative ions at the
same time
• SUM displays the total number of ions present
Long-term Recording of ion levels directly on to
included, easily accessible, external MicroSD
card.
Rechargeable LiPol Battery charges via USB-C
port with included charger, or from any laptop or
PC or external USB power pack.
Durable, Aluminum, Lighweight Handheld Case:
• measures 6.5” x 3” x 1.5”
(165mm x 76mm x 38mm)
• weighs less than 13oz. (368 grams)
Peak Hold Feature displays the highest ion level
until reset or power down.
Selectable Averaging can be set to none, or from
1 to 15 seconds for stable readings.
Selectable Automatic Re-zeroing for long-term
unattended operation and data capture.
Data Streaming, Recording and Display via
AlphaApp Windows PC software.
Versatile 3-in-1 combo accessory:
• easily slides on as a fold-out kickstand
• mounts to a standard tripod
• or attaches to a wall with included hardware
On-board temperature and humidity sensors, data
included on display and when streaming/recording.
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.
