Air Ion Counter, Model AIC2, Dual Range
Air is drawn in at the top of the meter, measured, and exits at the bottom. The display shows the ion count within 1 second and it continues to display the ion density in the air, showing any changes within 1 second after they occur. The "Ion Polarity" selection determines whether positive (+) or negative (-) ion density is measured. The meter operates on four AA batteries or an external 6V to 9VDC supply.
Please note: solids do not produce ions unless there is an energy source (such as radioactivity, high voltage or heat above about 600° C). For example, neither tourmaline nor "diodes" produce any ions at room temperature unless radioactive material has been added. However, liquids evaporating can produce ions.
The Air Ion Counter Model AIC2 is a handheld meter designed to measure ion density - the number of ions per cubic centimeter (ions/cm³) in air. It measures this number separately for positive and negative ions (+ and - ions are usually present simultaneously). This instrument is a true ion density meter, based on a Gerdien Tube Condenser design, and it contains a fan which draws air through the meter at a calibrated rate. The meter features two measuring ranges of 2 million and 200 million ions/cm³. For comparison, a typical outdoor environment has 100 to 1000 ions/cm³, both + and -. The 200 million ions/cc range is suitable for measuring close to electric ionizers or strong radioactive sources.

Measuring range: 2 million / 200 million ions per cm³
Resolution: 10 / 100 ions per cm³
Accuracy: ±20% of reading at 2 million, 1000 per cm³ at 200 million ±2% repeatability
The unpredictable nature of ion self-destruction in the air just outside the meter makes more accurate
(some ions are lost as air is redirected, positive and negative ions neutralize each other spontaneously,
Noise: 10 ions per cm³ (2 second averaging)
