MFS-07e High Frequency Induction Coil Magnetometer

The high-frequency induction coil magnetometer MFS-07e has been developed for applications in Audio Magnetotellurics (AMT) and Controlled Source Audio Magnetotellurics (CSAMT). Nevertheless, it covers a wide frequency range from 0.001 Hz up to 50 kHz and can also be used for standard MT applications. The MFS-07e shows outstanding low-noise characteristics, very low temperature drift of input offset voltage and offset current and a very stable transfer function over temperature and time. The MFS-07e is the result of more than 35 years of experience of metronix in the design, manufacture and application of induction coil magnetometers.

Metronix takes special care of the initial calibration of all MFS-07e magnetometers as part of the ISO9000-2000 certified production process. Tests have demonstrated an excellent long time stability of the transfer function.

The integrated calibration facility makes it easy for the user to perform an online calibration or test of the magnetometer´s transfer function. A differential test signal can simply be injected into the CAL input of the sensor.
