EMF Testers
EMF Testers
Electromagnetic fields are found everywhere on the planet. Whether they are caused by a cell phone, radio tower, an electric circuit or the earth itself, they surround us at all times. These fields can alter and negatively affect electrical circuits, especially once the strength of the field is increased. It is important to understand EMF strength and intensity when installing or using electrical devices close to a strong EMF source.
There are increasing worries about the negative health effects of electromagnetic fields especially of a very high intensity. There is little evidence of ill effects with low EMF strengths but many people would rather not chance exposure to something with this much potential energy. On a more practical scale, the effects have been obvious on electrical devices and the circuits must be specially designed to handle high EMF sources. An EMF Tester is a simple way to determine the strength of an EMF and make preparations accordingly. They are available in a variety of ranges depending on the circumstance.
