The induction coil
magnetometer LEMI-152 is intended to be used for the study of magnetic
field fluctuations in land conditions in the frequency band 0.001-10000
Hz. It can be used both autonomously with any analog registration unit
and as a part of a magnetotelluric station. Extremely high sensitivity
ensures excellent signal-to-noise ratio for ground measurements.
Low power consumption and wide power supply range allow for long period
measurements at remote sites. A rugged and waterproof housing combined
with a waterproof output connector prolong the sensor’s active lifetime
and ensure overall reliability. |
