An EMF meter is a handheld device that detects and measures electromagnetic fields (EMFs) in your environment by sensing changes in electric and magnetic fields or radiofrequency (RF) energy. It translates invisible energy waves into readable values so you can see how strong various EMFs are around electrical wiring, appliances, wireless devices, power lines, or other sources. Some meters measure a single type of field or direction, while more advanced tri-axis models capture multiple axes at once for a more complete picture.
People use EMF meters in technical, research, and home settings to explore where EMFs are strongest, compare different sources, or troubleshoot specific areas. An EMF meter can help you understand the electromagnetic landscape around you by showing where signals or fields are relatively higher or lower.
