There is a Trifield available that is supposed to have 100 times the electric 
field sensitivity of the regular Trifield, but even that is not very good.   I 
have one, and the needle just begins to move at 15 volts per meter electric 
field strength.   Not good enough, since people experience symptoms from a .01 
volt per meter field (if it contains the high frequencies).   
     Set to read radio and MW frequencies, the Trifield needle barely wiggles 
when I am two blocks away from a "tower farm" of radio and tv broadcasting 
towers.   The Electrosmog Detector, in comparison, makes a noise like six buzz 
saws in this same location. 
     The various meters described at 
www.lifeenergies.com/products/products.htm#hardware         are the ones I use and recommend.    (There are electric 
field meters that indicate specific frequency, but they are more pricey.)
     Most of the electrical pollution is in the 4 to 100 KHz range, with the 
greatest concentration at about 25-50 KHz.   The Graham Stetzer filters were 
specifically designed to remove these frequencies.
     The Graham Stetzer Microsurge meter was designed specifically to measure 
the level of electrical pollution present in any circuit you plug it into and 
give a digital readout.    
     It is not true that nobody really knows how much of a hazard all our EM 
exposures are.   A great deal more is known about this than most people 
realize.   Please see "The Health Effects of Manmade Electromagnetic Frequencies" at 
www.lifeenergies.com/pollution/hemef/index.htm .
     It has been presumed that field strength or power density would be the 
most important factor regarding biological effects of EMF/EMR, but this has not 
proven to be the case.   With some frequencies, there is more biological 
effect from weaker signals than from stronger ones.    In addition, different 
frequencies are related to different biological effects.   Even the time of day of 
the exposure, and the strength of the geomagnetic field at the particular 
site have an effect.   
     In short, we are now all part of a huge experiment.

     We borrowed the oscilloscope to look at what we had here, so I don't 
recall very clearly.    It was, however, even worse than the dirty current you 
can see at www.electricalpollution.com/images/MNschool.jpeg/.    This is a 
"snapshot" of 1/60 second of the electrical current in the circuit.   The nice even 
wave you see that makes one full wave across the screen is the 60 Hz.   (60 
Hz is 60 waves per second,   or one full wave per 1/60 second.) That is all 
that should be present.   The jagged lines, that are densely packed from side to 
side of sceen, are the electrical pollution.
     The image on the oscilloscope screen here at our home before we 
installed filters looked like a child had taken a pencil and scribbled up and down, up 
and down, across the screen, pretty much filling it.    As we plugged in the 
Graham Stetzer filters, those lines began to disappear, and we ended up with a 
remarkably cleaner wave form.   Not entirely clean, though.
     We now moniitor our power quality with the Graham Stetzer meter, which 
gives a simple digital reading.   20 GS units is a symptom-free level.   
Whether we can attain that depends on the loads on the line at a given time.   
Unfortunately, we are on the same substation line as a cheese factory, which has a 
lot of high-frequency producing equipment.

     The height of the waveform on the scope screen can indicate different 
things, depending on how the operator has the scope set.    In this case (the 
images I gave the url for), the amplitude (height) of the high frequency waves 
is milliVolts. 
     The more amplitude/height a wave has, the more energy it has.   
     Amplitude and amperes are not the same thing.
