This Air Ion Tester is designed for testing high level concentration of negative or positive air ion of air ion generator/ionizer, Nefful Negative Ion clothing, power balance wrist bands or other strong negative ion sources such as waterfall. With this tester you can know whether the air ion generator or air purifier is working in good state so you know when to change the filter of ion generator. The reading of the tester is correlative to the air ion concentration, but not exactly the number of it. In factor, this tester can only provide you a rough measurement to the air ion source. Please don't take it as an precision instrument.
For the resolution, refer to the sensitivity of the meter. Meter reading of 1 means that the concentration of ions in air is 1x10^4 or 10,000 ions per cc (cubic centimetre) of air. The meter is therefore not suitable for ion source that emits only a low concentration of ions.
In the case of negative ions from Nefful negative ion clothing fabric, frictional energy is imparted to the fabric through contact with our body. It is thus necessary to brush gently on the fabric surface to produce negative ions. The amount of ions generated depends on several factors including surrounding humidity, fabric surface area such as smooth, rough or uneven surface.
