Description:

The complete set of magnetometer consists of three LEMI-30 sensors and one communication unit (CAM unit), which connects the sensors to PC and provides their power supply, satellite synchronization of data sampling and digitizing.

The induction magnetometer LEMI-30 is intended for the study of magnetic field fluctuations in the frequency band 0.001 ... 30 Hz in land conditions and is ideal for ULF earthquake precursors monitoring. A novel method of strong damping of mains frequency is implemented there (see Frequency Response), what makes it convenient for using close to the populated area. All three LEMI 30 sensors are similar within 0,1 dB

• The magnetometer consists of:

- three LEMI-30 sensors

- the communication unit (CAM) which connects sensors with the personal computer and provides their power supply, satellite synchronization of data selection and digitization.
