Measuring EMFs

I would like to upgrade my diagnostic tools. I have the humble
trifield meter and I am not too sensitive so i cannot always tell.

I have heard about the body voltage meter from Graham & Stetzer. Is
that what i should start with?

BTW, four years ago a tried a bunch of GS filters and an electritian
came and measured their effects and there were none. His name was
Steven Scott, I think. Maybe he did not measure high fequencies. I was
not informed enough at the time to ask. I did not notice a difference.

Thanks.
Right now i am looking for a simple classification scheme. What I
understand is that there three kinds of readings to be taken that
require three meters. I give an example of a cheap meter in US dollars
as listed on Lessemf.com.

Low frequency: Trifield meter, $100 US.
Hi Frequency noise on the wires: Stetzer meter $100
Radio and microwaves in the air: Electrosmog detector. $90.

What else is there as a general category not covered here?

Man-made EMF sources have a tendency to lower the ratio of
negative ions (beneficial) to positive ions (harmful), so
I suppose an ion counter might be useful as well.

People also talk of longitudinal waves, but there appears
to be no meter for that.

Hello Martin,

I am sorry, but I must correct you there.

The amount of negative air ions stand apart from the amount of positive
iones.

Normally many, many years ago, we had 2.000-4.000 negative air ions/cm3.
Nowadays I find 300-400 negative air ions/cm3.
In the vicinity of phones and masts, the amount goes down to 100 even to 80
/cm3.

Somebody in Switserland measured the amount at a distance of 300 meters from
masts, and then at 60 meters.
And there, the amount was only 50 % of the amounf at 300 meters away.

The same goes for a mobile phone, as well as a DECT phone, from 1 meter to
15 cm.

We need many negative air ions.

Positive air ions are not influenced by high frequencies.
They have a coupling with radioactivity, and sure with radon gas.
So, the higher the amount of positive air-ions, the more radon gas will be
there.

Regarding longitudinal waves, there is indeed no meter for it.
