Methods and instruments for this kind of analysis are here given in the form of a project: a "Ions meter", to reveal and characterize the properties of the air ions, and "APEC 300", an advanced electronic device, both instruments are with a HPR (high power of resolution). APEC 300 can give the response to the possible health effects by measurements of two electrocuteaneous parameter: the potential level and the impedance. The power of resolution of APEC 300 is much higher than that of other usual devices, for instance, the EAV ones (electroacupuncture), this instrument will be completely ready within few weeks.展开更多
