Low-frequency EMF refers to the very bottom end of the electromagnetic spectrum, well below radio frequencies.

In our daily lives, low-frequency EMF is very pervasive, for one reason: our mains electric power falls within this range, with a frequency of 50 or 60 cycles per second (depending on country).

Low-frequency EMF has one peculiar quality: the magnetic portion and the electrical portion behave differently, and can be measured separately.

Some EMF meters measure both magnetic and electrical fields, others just measure the magnetic field. The latter are sometimes called Gaussmeters, because Gauss is one unit of measure for magnetic fields. (The other unit is Tesla.)

The magnetic field is thought to have more relevance for our health because it is capable of penetrating a person’s body, whereas the electric field has no penetrating power.

Low-frequency magnetic fields will pass through just about anything, including rock, concrete, brick walls and steel, so they have no trouble going through a human body – bones and all.

There are a number of very cheap meters in this category, but their sensitivity is usually poor, and accuracy may not be great either.

We have selected a few that we think are of good quality, and in the case of the Tenmars TM-192, we have used this meter for professional work and can recommend it.
