LEMI-118
Product type:
Induction coil magnetometer
Product description:
The LEMI-118 induction coil magnetometer is intended for the study of magnetic field fluctuation in the frequency band 1Hz to 70,000 Hz. It can be used both as a part of a magnetic measuring system and autonomously with any state-of-the-art registration unit.
Application description:
The LEMI-118 induction coil is used for passive and active geophysical measurements like CSAMT in a wide frequency range. The band of frequencies the sensor operates in is suited for shallow applications like hydro-geophysics or mining.
Highlights:
Wide frequency band
Low power consumption
Low noise
