Electronic magnetic field indicator EMFI-1

The electronic magnetic field indicator EMFI-1 has been designed for detection of the presence of magnetic fields and detection of residual flux density of ferromagnetic elements, e.g. steel elements magnetized as a result of their mechanical working in a production process or steel elements of measuring devices (watt-hour meters, water meters, gas meters, etc.) magnetized through strong magnetic fields, e.g. coming from neodymium magnets.
