Defining and measuring the harmful electrical pollution is analogous to defining and measuring harmful drinking water. The problem is not the water; it is not (in general) the 60 Hz electric power we all enjoy in our homes and offices; it is what comes with the water, and what comes with the 60 Hz power! The pollution is the problem!
Just as a water meter is not an appropriate instrument to measure water pollution, normal meters are not appropriate instruments to measure electrical pollution. There is a subtle but fundamental difference between measuring the volume of polluted water or polluted electricity and measuring only the amount of pollution present. Most electrical meters measure the amount of polluted electrical energy; the new GS emf meter measures the actual amount of harmful electrical pollution.
The animal or human is the ultimate “meter” in the sense that we are only concerned with what is harmful and what the harmful levels of electrical pollution are. Empirical evidence, buttressed by theory, shows that electric current enters the body more readily at higher frequencies, and that current through the body (body current) is increasingly harmful at higher frequencies. Therefore, these higher frequencies are the electric "pollutants" with which we should be concerned.
The GS meter reflects this frequency dependence in its measurements. The GS meter measures the sum of the voltages for frequencies above (but not including) 60 Hz, weighing the higher frequencies to reflect their greater impact on humans and animals. Thus, this innovative emf meter measures electrical pollution on the home or office power lines.
