MF EASY, DC-400 kHz, MAGNETIC FIELD EXPOSURE ASSESSMENT SYSTEM
The MF EASY is a scalable and flexible multichannel measurement and assessment system for magnetic fields in the frequency range DC – 400 kHz. It is available with 5 or 10 (on request up to 15) fully isotropic measurement channels enabling simultaneous magnetic field measurements on 5 or 10 (15) measurement positions.
Different standard probe types (sizes and shapes) are available for the MF EASY. Customized probes are available on request. Iso-centrically arranged coil and Hall sensor enable a measurement frequency range from DC to 400 kHz and a measurement sensitivity suitable for assessing human exposure.
