The handheld Air Ion Meter measures ion density, which is the number of ions per cubic centimeter (ions/cc) of air in a given space. 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 (Gerdien Condenser) design, complete with “air-through” design where the internal fan pulls air through the meter at a calibrated rate. The standard model measures up to 2 million ions/cc (for comparison, outdoor air typically has 100 to 1000 ions/cc, both + and -). The 2 million range is sufficient for almost all indoor environmental use cases. If you will be measuring in very close proximity to the ionizers, models with ranges of 20 million and 200 million ions/cc are also available.

The air ion sensor is designed for ease-of-use for contractors and building owners to verify actual ion levels.

Accurate and Easy to Use Ionization Meter

The digital readout is a direct reading and special circuitry has been employed to provide high accuracy and to minimize variations in air ion readings. The meter automatically zeros itself at each startup, and every ten minutes during prolonged continuous use to avoid erroneous readings caused by static buildup. The air ion sensor has a rechargeable battery and provides about 6 hours of continuous operation – more than enough to survey even large buildings. The charger plugs into a standard wall outlet.

Plasma Air Ion Meter

The Plasma Air Ion Meter has a digital readout which provides a direct reading. Special circuitry minimizes variations in ion sensor readings. The meter automatically zeros itself at each startup, and every ten minutes during prolonged continuous use to avoid erroneous readings caused by static buildup. The meter has a rechargeable battery and provides about 6 hours of continuous operation – more than enough to survey even large buildings. The charger plugs into any wall outlet.
