TrifieldĀ® EMF Meter Model TF2
229,00 €
The TriField EMF Meter is an AC gaussmeter, AC electric field meter, and radio power density meter in a single unit, that combines all the features needed for fast, accurate measurements of electromagnetic fields (EMF). In addition to standard AC measurement modes, a special frequency weighted mode will properly scale the magnetic and electric measurements to indicate the full magnitude of currents produced by each type of field inside the human body.
EMF Shielding Techniques
Radio waves and microwaves can be reflected off a metal sheet in exactly the same way that light reflects from a mirror. The metal sheet can be very thin and can even have holes in it (as long as the holes are small: smaller than the wavelength that is to be reflected). Therefore, aluminum foil, aluminum screen door material (or metal mesh), or even Mylar space blankets* will reflect radio waves. Aluminum siding also works. If an outdoor cell tower is transmitting microwaves, and you hang a metal sheet on the wall between the cell tower and you, the direct microwave radiation will be reflected back outdoors. Of course there still may be some microwaves getting indoors because of reflection off of structures in back of you (think of it this way: if you were outdoors and stood under an umbrella to shield yourself from direct sunlight, some indirect light would still be present).
