About The Company
GF Instruments is a private owned geophysical company settled in The Czech Republic (EU).
The company's two main activities are:
- Development, manufacturing, sale and rental of measuring instruments for geophysical, geological, environmental and laboratory use including gamma-ray spectrometers and dose rate meters, DC resistivity systems, electromagnetic conductivity meters, magnetic susceptibility meters, metal detectors, laboratory instruments and special equipment based on above mentioned methods designed to the user’s request.
- Providing of development of methods for near-surface geophysical survey as well as consulting and services in the field of geology, engineering geology and UXO survey.
Multidepth conductivity meters CMD-E and CMD-ME have created new world standards for shallow EM survey. They
allow the calibrated evaluation of depth conductivity gradient in one measuring pass. We have increased our
production capacity so their current delivery time is under two weeks.
Permanent interest of our customers allows us to keep the gamma-ray spectrometer prices on a stable low level.
Discover their wide offer containing many models equipped with a variety of detectors
(using both natural and artificial way of spectrum stabilization) designed for classic and special
We have introduced our new magnetic susceptibility meter Multikappa that allows depth graded field
survey suitable for archaelogical and geological studies. Measured values in the range from
10-6 to 1 are calibrated in SI units.
Resistivity and IP
To meet the requirements of our clients, we have extended the selection of multielectrode cables (see section
Resistivity and IP – Recommended sets). Passive and active cables are offered in a range of complete sets based
on powerful ARES and ARES II units, all at a significant price reduction. The sets with short delivery time are
suitable for a wide spectrum of tasks (from common single channel survey to large 10-channel, water, borehole
and other special surveys).
We recommend to pay attention to our methodical guides for electromagnetic conductivity survey
as well as for resistivity and IP imaging. Those brochures contain both theoretical introduction and many typical examples of applications.
In the year 2014 you can meet us at our booth at the following main exhibitions:
DGG - March 10 - 13, Karlsruhe, Germany
SAGEEP - March 16 - 19, Boston, Massachusetts, USA
EAGE Near Surface - September 14 - 18, Athens, Greece
