product description:
The TriField Natural EM Meter was designed to do field measurements for special research. It detects changes in extremely weak static (DC or "natural")
electric and magnetic fields, and signals with both a tone and the movement of a needle-type gauge if either the electric or magnetic field changes
from previous levels.
A radio and microwave detector is also included, which reads radio power directly. Because man-made AC electric and magnetic fields are very common
and could interfere with readings of static fields, the meter has been designed to ignore AC fields. Normal construction materials don t block magnetic
fields, so the meter can be placed indoors and will work equally well, and due to the built-in tone, it can be used in the dark, and will sound the
tone at whatever level of field the user sets.
Operates on a standard 9-volt battery. Can detect geomagnetic storms caused by unusual solar activity interacting with the ionosphere (which results in
rapid changes of up to 10% in the Earth s magnetic field), as well as the electrical activity of ordinary thunderstorms. Includes custom made aluminium case
which fits Trifield Natural EM Meter as well as additional accessories. This carrying case allows to to protect your Trifield device and keep all the parts
and components organized.
