Helmholtz coils

Our Helmholtz coils are designed to test the immunity of electronic equipment to magnetic fields, for instance according to European standards (CE) or to MIL-standards. The field is homogeneous for most of the volume and is sufficiently precise to calibrate magnetic field probes. Special versions are designed to test the immunity of watches to DC magnetic fields, for instance according to ISO 764 or to NIHS 90-10. Very high DC or AC fields can also be tested with some of these Helmholtz coils.
