GF Instruments, s.r.o. products

Geological and geotechnical survey, agriculture, archaeology, groundwater protection, environmental monitoring, raw material prospecting, metal object and network detection. Large family of CMD electromagnetic conductivity meters is designed for survey depth ranges from 0.15 to 60 m. Used contactless method allows fast measurement of conductivity and inphase under all field conditions (including very dry and icy ground). Probes are equipped with 1, 3 or 6 receivers with excellent temperature stability. This way makes high resolution depth graded mapping as well as imaging of sections possible and useful for wide range of walking and moving applications.

Groundwater exploration, geotechnical investigation, monitoring of dams and dikes, environmental studies, geological survey, mineral prospecting, archaeology, detecting of cavities and buried objects, underwater, marine, borehole and cross-hole measurements. ARES II represents a well equipped resistivity and IP imaging system. Its advantages can be applied especially for large 2D and 3D surveys (operating up to 65,000 electrodes), for continuous survey from water level and for programable monitoring of structures. Its variability, easy field operation (without PC), feeding from a standard 12 V battery or from a generator, rich support of standard and special electrode arrays and compatibility with widespread interpretation software makes ARES useful tool for working groups and research teams.

ARES II remote controlhelps you in all cases where measuring conditions make the work difficult. You can operate ARES II system from a comfortable place with full access to the measuring parameters and to the actual results; it is possible to check the measured apparent / model section at any time during the measurement, and to remeasure its chosen part. Remote control support is a standard part of ARES II software. For the basic USB connection no additional cost is required.

ARES represents a well equipped resistivity and IP imaging system. Its variability, easy field operation (without PC), feeding from a standard 12 V battery or from a generator, rich support of standard and special electrode arrays and compatibility with widespread interpretation software makes ARES a cost effective and useful tool for working groups and research teams.

Groundwater explorations in arid and semi-arid areas, deep geological surveys, mineral prospecting, structural studies.Geoelectric Power Sounder GEPS-2000is a device for data acquisition and interpretation of deep VES (vertical electrical sounding) as well as for 8 channel profiling (resistivity and IP sections). It can be used for measurements up to 1000 – 2000 m depth allowing both high voltage and high current injection of transmitter current according to real measuring conditions.

Land Gravity Meter LG-1 Galileooffered as a new product of GF Instruments is ready to match all needs of up-to-date field gravity survey. Its shock resistance is supported by lightweight sensor based on temperature balanced quartz core. Stable measuring features are completed with advanced technology of signal processing. The detachable control unit allows to adjust the leveling and to observe the data quality during measurement. Significant cost effectivity (purchase, operational and service expenses), together with traditional resourceful consulting, make LG-1 another useful family member of geophysical measuring tools made by GF Instruments.

SGR represents a handheld, ruggedized and simply operated instrument for field and industrial use. This unit is equipped with an acoustic output (pitch response). These features are completed with water tightness and resistance against mechanical shocks. The unit is powered by standard, exchangeable, single use or rechargeable C cells.

Multi Kappa instrument serves for fast field survey allowing both spot measurement and mapping by means of several probes. Together with GF Instruments traditional pocket magnetic susceptibility meters cover wide range of demands for accurate susceptibility measurement on ground surface, outcrops and samples of rock and soil. Original efficient way of temperature stabilizing allows profiling without frequent zero setting. Fast sampling rate with GPS positioning can be appreciated at moving applications. Exchangeable coils with various diameters make choice of appropriate depth range and horizontal resolution possible.

The SM-20 magnetic susceptibility meter is very useful tool for a number of geological and geophysical applications where the unique sensitivity of 10-6 SI units together with its small, shirt-pocket size and low weight are appreciated. The SM-20 is designed especially for field geologists and for fast laboratory assays for analysis and classification of rock types or drill core samples. Those measurements allow basic differentiation of rocks (diamagnetic, paramagnetic and ferromagnetic) and their precise susceptibility quantification.
