Overhauser magnetometer MiniMag


Item ID: MiniMag


The product was successfully added to basket
Main features:
  • Overhauser magnetometer
  • Built-in GLONASS / GPS module
  • Range: 20 000–100 000 nT
  • The most compact in the world

MiniMag is one of the most advanced versions of high-precision Overhauser magnetometers on the market. It enables one to measure the modulus of full vector of geomagnetic field with the highest accuracy. The device can be used as a field hand-held magnetometer or stand-alone base magnetic station with a programmable measurement cycle. Automatic coordinate referencing of observation points and time synchronization of the field magnetometer and base magnetic station are provided by the receiver built-in in the GLONASS / GPS console and the MagGPS software.

Areas of MiniMag application:
  • Mining of solid mineral deposits
  • Engineering surveys
  • Regional geological exploration
  • Geological exploration for oil and gas
  • Archaeological surveys

Distinctive features of the latest generation of MiniMag magnetometers compared with its previous versions:

  • Built-in GLONASS / GPS module
  • Communication with PC via USB interface
  • Additional built-in memory with MagGPS installation software that provides for downloading, processing, visualization and saving data in convenient formats
  • New convenient rugged case
  • Cables of new design with reinforced connectors
  • New ergonomic harness for even more comfortable work
  • New firmware provides enhanced gradient tolerance and noise immunity
