EMF Meter
An EMF Meter is a device used to measure electromagnetic fields (EMF) in the environment. These fields are produced by various sources, including electrical appliances, power lines, and wireless devices. EMF Meters can help identify areas with high levels of electromagnetic radiation, which some people believe may have health implications.
There are different types of EMF Meters, including analog and digital models. Analog meters use a needle to indicate the strength of the EMF, while digital meters provide numerical readings. Many people use these devices for personal safety, scientific research, or even paranormal investigations, as they are often associated with the presence of ghosts or spirits.
