Air Ion Counter

The Air Ion Counter Model AIC is a handheld meter designed to measure ion density – the number of ions per cubic centimeter (ions/cc) 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 unit comes as a dual-range model; AIC2-R1 has selectable maximum ranges of both 2 million and 200 million ions/cc. For comparison, a typical outdoor environment has 100 to 1000 ions/cc, both + and -. The 200 million ions/cc range is suitable for measuring close to electric ionizers or strong radioactive sources.
Features
Large Backlit Graphic Display
Peak Level Capture
Quiet High Q Fan
16-Hour Battery Life
AC Power Adapter (included)
Data Recording
Data Transfer via USB
Data Plotting via Included PC Application
Data Recording USB:
The USB Port in conjunction with AlphaApp provides real time ion level data and plotting as well as the ability to upload and plot recorded ion levels. Recording of an ion level can be initiated manually by the user or automatically at intervals of a half a second to 120 seconds. At a 5 second interval, up to 420 hours if data may be stored in the meter nonvolatile memory.
