Hello,
in a home, there are several dangers lurking at you.
You can not see them, you cannot hear them and you cannot taste them, but
they are there.
With a building biology search, many items are looked after.
But many people want to investigate for themselves and consider what meters
they need.
I want to give here my personal impression, for people in the USA.
Others may have another opinion, but this is for starters.
1. We have the high frequency from mobile phone masts and DECT telephones.
For shielding, it is neccessary to know how much is coming from where.
My advice is the Gigahertz HF Analyser 35C or the more sophisticated 58B.
In a few months the 59B is coming, but that one is more expensive, and for
professionals.
This meter starts at 800 MHz till 2.5 GHz. All frequencies below 800 MHz are
filtered out.
That means, that radio and television waves do not interfere with the
signals you want to measure.
This meter does not have a AGC, automatic gain control, other meters do
have.
So the signals you pick up, are not amplified, but real, and right with the
value on display.
In my opinion, the value/price for this meter is right.
Lessemf has it in its programm.
One uses this meter regularly, to check for changes.
2. Electrical alternating fields are not so a great concern to me.
The magnetic alternating fields are.
Gigahertz has a nice meter for it. ME3030B. You may measure electrical
alternating fields as well as the magnetic alternating fields by pressing a
button. (See Lessemf)
But, for measuring magnetic fields, ons must measure the X-, Y-, and Z-axis.
Those values must be quadrupled, added, and taking the quare root of it. One
needs a calculator for it.
I use a 3D Teslameter, who calculates that himself. Just point and read.
The 3-axis AC digital AC Gauss meter from Bell. See Lessemf.
3. Magnetic static fields.
That is a meter for DC magnetics, which occur in metal parts that have
become magnetic. Like pipings under the floor, metal support beams, metal
parts on beds, earth beams, etc.
I have a simple Magnetometer according to Cromm, which is no longer in
production.
Perhaps the DC Magnetometer from AlphaLab (Trifield) is a choice.
On the other hand, this is not something one measures everyday, but it can
be an enormous pest.
