MiniMag — is the most advanced and lightest Overhauser magnetometer in the World. The instrument is intended for high-precision measurements of the Earth’s total field. MiniMag could be deployed as both rover hand-held magnetometer and autonomous or remote base station (BS).Built-in and external GNSS receiver
Integrated multi-system GPS/GLONASS GNSS receiver enables automatic coordinate gridding of measurement stations and time synchronization with the base station. In cases when the connection of an external receiver is required, MiniMag can provide it using standard NMEA 0183 protocol via RS-232 connection.Reliable instrument for magnetic observatories
High sensitivity and outstanding absolute accuracy (less than 0.1 nT) alongside with high sampling rate make MiniMag an excellent tool for the equipping of magnetic observatories. Real-time data transfer can be realized via either USB or RS-232 interfaces. An external GNSS receiver installed outside can provide the accurate time synchronization in any magnetic observatory.Display and beeper
Both text and graphic data presentations are available on the built-in display of MiniMag. Convenient signal quality estimation is realized using sound beeper. Such user-friendly interface makes the magnetometer very easy to use for the real-time UXO and utility detection.Metrology – guarantee of high accuracy
Each particular MiniMag has its own Certificate issued by authorized organization based on the testing in the entire operation range in the certified magnetic induction measure. We check such parameters as RMSE; sensitivity and orientation error. Metrological Certificate confirms the instrument quality and guarantees the reliability of collected data.Reliability and Warranty
Our R&D specialists have big experience in magnetometry surveys, that is why we understand that field instruments must be very reliable whereas the maintenance and repair must be fast and simple. All of our magnetometers are provided with 3-year Warranty and our technicians are ready to assist you if any problem arises.
You can also take advantage of our trade-in program and change your old instruments to the new MiniMag with discounts.Important details
We realize that geophysical instruments must not have useless details, that’s why we are focused on technical features that make operation as comfortable as possible.
Magnetometry survey forward modelling and data inversion may be successfully carried out with advanced ZondGM2d and ZondGM3d software packages.
