Emf Meter is a great tool to detect and analyze the strength of the electromagnetic field in your environment. It can be used to detect ghosts, monitor pollution levels, or just to browse the Internet with a whole lot more privacy.
It works by measuring the magnetic field with an embedded sensor. The sensor is designed to be as accurate as possible, and the results are displayed in micro Tesla (µT).
The sensor is built into the device, so it doesn't need to be connected to an external device. This makes it perfect for use in your home or in a public place.
The sensor can be used to detect ghosts, monitor pollution levels, browse the Internet, and a whole lot more.
