The product was successfully added to basket
Main features:
  • Mobility and high efficiency
  • Possible to operate on water areas and any road surface
  • Capacitive coupling type
  • Depth of investigation up to 30-50 m

Radiomagnetotelluric sounding (RMT) in motion is used on water areas and land and uses signals of radio stations in 10-1000 kHz frequencies range as transmitting signal. A compact vehicles are used to perform soundlings: cars, off-road vehicles, boats.  Graphs of resistivity and phase of the impedance distribution are shown as a result of measurements.

RMT is used:

  • To perform rapid geological investigations,
  • To search for mineral deposits,
  • Hydrogeological investigations,
  • Engineering investigations,
  • Ecological investigations.

The main features of the system are:

  • Possibility to record time sequences or magnetic and electric fields’ spectrograms;
  • Fast data quality control;
  • Possibility to save observed data to built-in memory or external PC.

The use of capacitive line allows to perfoerm investigations at any time of the year on any surface, including snow, ice, soil, asphalt, concrete, pebbles etc. Mathematical model of plane wave permits to interpret data in 1-2 up to 30-50 m depth of investigation range. With the speed of surveying 8-10 km/h and step 20-30 m between soundings, RMT-M system allows to get 40-50 km of data (profiles) per day.
