This small, lightweight, portable ion meter can measure positive (+) or negative (-) ions in the air, and can also measure the electrical (ionic) charge on textile materials like clothing, curtains, sheets, or any other fabrics. It covers a good middle range of ion concentrations from 10000 ions/cc up to 20,000,000 ions/cc.
To measure high ion concentrations, you can move the ion detector farther away from the source and extrapolate near-field ion concentrations by the ratio of the distance cubed (r3).
To measure low ion concentrations, you can move the ion detector closer to the source and similarly extrapolate far-field ion concentrations with the same distance cubed (r3) formula.
(For very sensitive and precise ionic measurements, our IOD40 is recommended.)
