BM-SCAN - Magnetic field strenght meter

1 - Role of the measurer

The field measurer has been designed to ensure that magnetic loop systems are installed and
certified according to the new IEC 60118-4 standard. When these standards are respected,
the comfort of the user will be identical wherever he is using his prosthesis equipped with the
T position.

The BM-SCAN makes it possible to commission an installation and certify its conformity.

You can then complete the certificate of compliance.
