This Air Ion Tester is designed for test high level concentration of negative air ion of air ion generator. With it you can estimate whether the air ion generator or air purifier is working in good state. 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

The technician wants you know the air ion concentration in the atmosphere is effected by physical properties of the earth's environment, the time variation and atmospheric pollutants, climate, seasonal changes. Air concentration, ion polarity, size is an important criterion for evaluation of environmental quality, environmental pollution, weather and the effects to human. Usually, a high value of the negative ions means a good quality of the air.So it is normal , if it keeps jumping all over and never gives a steady reading.
