LEMI-121
Product type:
Induction coil magnetometer
Product description:
The LEMI-121 induction coil magnetometer features high sensitivity and low noise combined with a very small form factor. The optimized feedback design ensures an excellent signal-to-noise ratio for exact measurements. Strengthened rugged housing and output connector prolong sensor active lifetime and increase overall reliability. Low power consumption and wide frequency range allow long-term measurements at remote sites.
Application description:
Its small dimensions and lightweight makes the LEMI-121induction coil magnetometer the ideal sensor for magnetotelluric studies in remote locations. Intended for the study of magnetic field fluctuations in the frequency band 0.0001-500 Hz it can be used in areas where the use of LEMI-120 induction coil magnetometers is not a possible or as vertical sensor in locations where deep holes are not an option. LEMI-121 induction coil magnetometer can be used both autonomously with any state of the art analog registration unit or as a part of geophysical equipment, e.g., magnetotelluric stations.
Highlights:
Wide frequency range: 0.0001 Hz to 500 Hz
Low power consumption
Only 560 mm long
Weights only 4 kg
