Induction magnetometer LEMI-118 for the study of magnetic field fluctuation in the frequency band 1 – 70000 Hz

Description

Induction coil magnetometer LEMI-118 is intended for the study of magnetic field fluctuation in the frequency band 1 – 70000 Hz in field environment. It can be used both as a part of magnetic measuring system and autonomously with any analogue or digital registration unit.


LEMI-118 magnetometer

Main technical parameters
