INDUCTION MAGNETOMETER LEMI-118


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.
