LEMI-152

   

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.
