Air Ion Tester untuk mengukur konsentrasi Ion Negatif dan Positif pada udara atau pada tekstil. Dengan alat ini kita bisa test apakah Air Purifier yg dipakai berfungsi dengan baik

This Air Ion Tester is designed to test high level concentration of + or - air ion.

It is effective to test the electric charge on the surface of textile.
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.
