Geophysical instruments

Since 1994 we have been developing and applying instruments for Induced Polarization (IP), Resistivity and Excitation-at-the-mass methods of electrical exploration.

Improvements of these instruments are still at progress. Our geophysical instruments are produced at up-to-date technological level, with application of microprocessor techniques and high technologies.

Case histories of application of these instruments in various climatic and geological conditions have shown their high reliability and efficiency.

The instruments are properly certificated and produced in small series. We can produce and sell these instruments to other companies under special contracts. During last years, we had sold several units of instrumentation and software to partner companies in Armenia and Uzbekistan, and users responded that our products proved to be easier to use and more reliable that similar products from other producers.

IP Time Domain Measuring Instrument TLR-IP-003

IP Time Domain Measuring Instrument TLR-IP-003

TLR-IP-003 is an instrument for field geophysical IP prospecting. The signal measured should be shaped as alternate polarity impulses (APL-2). During measuring process, this instrument makes one measurement per impulse. The pause time interval is divided into several sub-intervals (strobes), and a separate measurement is made for each strobe as the strobe average. At each point of measurements, a cycle of measurements is performed, and relative error is calculated for each sequential cumulative set of measurements. The procedure is terminated automatically when the ordered precision is achieved. Measured data are stored in memory of the device and then can be transferred to computer.

Electric generators of TLT series

These generators have been especially developed and produced for electrical prospecting by means of Induced Polarization (IP), Resistivity and Excitation-at-the-mass methods. Currently, three versions of these generators are available, differing on launch power: TLT-45 (45 W), TLT-1000 (1000 W), TLT-1400 (1400 W) and TLT-5000 (5000 W), that allows applying them to solving of wide range of geophysical problems in geological engineering, hydrogeology and mineral exploration.

These generators produce alternate polarity impulses to transmit them into grounded electrical supply line АВ. The current forms in the line АВ alternate polarity impulses with pauses between them (mode RPI-2) or without pauses (mode RPI-1). A value of the current can be automatically stabilized.
